No need for these to be instance methods on ABstractSyntaxFacts | ./docs/features/ExperimentalAttribute.md | ExperimentalAttribute
=====================
Report warnings for references to types and members marked with `Windows.Foundation.Metadata.ExperimentalAttribute`.
```
namespace Windows.Foundation.Metadata
{
[AttributeUsage(
AttributeTargets.Class | AttributeTargets.Struct | AttributeTargets.Enum |
AttributeTargets.Interface | AttributeTargets.Delegate,
AllowMultiple = false)]
public sealed class ExperimentalAttribute : Attribute
{
}
}
```
## Warnings
The warning message is a specific message, where `'{0}'` is the fully-qualified type or member name.
```
'{0}' is for evaluation purposes only and is subject to change or removal in future updates.
```
The warning is reported for any reference to a type or member marked with the attribute.
(The `AttributeUsage` is for types only so the attribute cannot be applied to non-type members from C# or VB,
but the attribute could be applied to non-type members outside of C# or VB.)
```
[Experimental]
class A
{
internal object F;
internal static object G;
internal class B { }
}
class C
{
static void Main()
{
F(default(A)); // warning CS08305: 'A' is for evaluation purposes only ...
F(typeof(A)); // warning CS08305: 'A' is for evaluation purposes only ...
F(nameof(A)); // warning CS08305: 'A' is for evaluation purposes only ...
var a = new A(); // warning CS08305: 'A' is for evaluation purposes only ...
F(a.F);
F(A.G); // warning CS08305: 'A' is for evaluation purposes only ...
F<A.B>(null); // warning CS08305: 'A' is for evaluation purposes only ...
}
static void F<T>(T t)
{
}
}
```
The attribute is not inherited from base types or overridden members.
```
[Experimental]
class A<T>
{
[Experimental]
internal virtual void F()
{
}
}
class B : A<int> // warning CS08305: 'A<int>' is for evaluation purposes only ...
{
internal override void F()
{
base.F(); // warning CS08305: 'A<int>.F' is for evaluation purposes only ...
}
}
class C
{
static void F(A<object> a, B b) // warning CS08305: 'A<object>' is for evaluation purposes only ...
{
a.F(); // warning CS08305: 'A<object>.F' is for evaluation purposes only ...
b.F();
}
}
```
There is no automatic suppression of warnings: warnings are generated for all references, even within `[Experimental]` members.
Suppressing the warning requires an explicit compiler option or `#pragma`.
```
[Experimental] enum E { }
[Experimental]
class C
{
private C(E e) // warning CS08305: 'E' is for evaluation purposes only ...
{
}
internal static C Create() // warning CS08305: 'C' is for evaluation purposes only ...
{
return Create(0);
}
#pragma warning disable 8305
internal static C Create(E e)
{
return new C(e);
}
}
```
## ObsoleteAttribute and DeprecatedAttribute
`ExperimentalAttribute` is independent of `System.ObsoleteAttribute` or `Windows.Framework.Metadata.DeprecatedAttribute`.
Warnings for `[Experimental]` are reported within `[Obsolete]` or `[Deprecated]` members.
Warnings and errors for `[Obsolete]` and `[Deprecated]` are reported inside `[Experimental]` members.
```
[Obsolete]
class A
{
static object F() => new C(); // warning CS08305: 'C' is for evaluation purposes only ...
}
[Deprecated(null, DeprecationType.Deprecate, 0)]
class B
{
static object F() => new C(); // warning CS08305: 'C' is for evaluation purposes only ...
}
[Experimental]
class C
{
static object F() => new B(); // warning CS0612: 'B' is obsolete
}
```
Warnings and errors for `[Obsolete]` and `[Deprecated]` are reported instead of `[Experimental]` if there are multiple attributes.
```
[Obsolete]
[Experimental]
class A
{
}
[Experimental]
[Deprecated(null, DeprecationType.Deprecate, 0)]
class B

class C

static B G() => null; // warning CS0612: 'B' is obsolete
}

/// <list type="bullet">
/// <item>
/// 'IsXXX' where 'XXX' exactly matches one of the same named syntax (node, token, trivia, list, etc.) constructs that
/// both C# and VB have. For example 'IsSimpleName' to correspond to C# and VB's SimpleNameSyntax node. These 'checking'
/// methods should never fail. For non leaf node types this should be implemented as a typecheck ('is' in C#, 'typeof ... is'
/// in VB). For leaf nodes, this should be implemented by deffering to <see cref="ISyntaxKinds"/> to check against the
/// raw kind of the node.
/// </item>
/// <item>
/// 'GetPartsOfXXX(SyntaxNode node, out SyntaxNode/SyntaxToken part1, ...)' where 'XXX' one of the same named Syntax constructs
/// that both C# and VB have, and where the returned parts correspond to the members those nodes have in common across the
/// languages. For example 'GetPartsOfQualifiedName(SyntaxNode node, out SyntaxNode left, out SyntaxToken dotToken, out SyntaxNode right)'
/// VB. These functions should throw if passed a node that the corresponding 'IsXXX' did not return <see langword="true"/> for.
/// For nodes that only have a single child, 'GetPartsOfXXX' is not not needed and can be replaced with the easier to use
/// 'GetXXXOfYYY' to get that single child.
/// </item>
/// <item>
/// 'GetXxxOfYYY' where 'XXX' matches the name of a property on a 'YYY' syntax construct that both C# and VB have. For
/// example 'GetExpressionOfMemberAccessExpression' corresponding to MemberAccessExpressionsyntax.Expression in both C# and
/// VB. These functions should throw if passed a node that the corresponding 'IsYYY' did not return <see langword="true"/> for.
/// For nodes that only have a single child, these functions can stay here. For nodes with multiple children, these should migrate
/// to <see cref="ISyntaxFactsExtensions"/> and be built off of 'GetPartsOfXXX'.
/// </item>
/// <item>
/// Absolutely trivial questions that relate to syntax and can be asked sensibly of each language. For example,
/// if certain constructs (like 'patterns') are supported in that language or not.
/// </item>
/// </list>
///
/// <para>Importantly, avoid:</para>
///
/// <list type="bullet">
/// <item>
/// Functions that attempt to blur the lines between similar constructs in the same language. For example, a QualifiedName
/// is not the same as a MemberAccessExpression (despite A.B being representable as either depending on context).
/// Features that need to handle both should make it clear that they are doing so, showing that they're doing the right
/// thing for the contexts each can arise in (for the above example in 'type' vs 'expression' contexts).
/// </item>
/// <item>
/// Functions which are effectively specific to a single feature are are just trying to find a place to place complex
/// feature logic in a place such that it can run over VB or C#. For example, a function to determine if a position
/// is on the 'header' of a node. a 'header' is a not a well defined syntax concept that can be trivially asked of
/// nodes in either language. It is an excapsulation of a feature (or set of features) level idea that should be in
/// its own dedicated service.
/// </item>
/// <item>
/// Functions that mutate or update syntax constructs for example 'WithXXX'. These should be on SyntaxGenerator or
/// some other feature specific service.
/// </item>
/// <item>
/// Functions that a single item when one language may allow for multiple. For example 'GetIdentifierOfVariableDeclarator'.
/// In VB a VariableDeclarator can itself have several names, so calling code must be written to check for that and handle
/// it apropriately. Functions like this make it seem like that doesn't need to be considered, easily allowing for bugs
/// to creep in.
/// </item>
/// <item>
/// Abbreviating or otherwise changing the names that C# and VB share here. For example use 'ObjectCreationExpression'
/// not 'ObjectCreation'. This prevents accidental duplication and keeps consistency with all members.
/// </item>
/// </list>
/// </summary>
/// <remarks>
/// Many helpers in this type currently violate the above 'dos' and 'do nots'. They should be removed and either
/// inlined directly into the feature that needs if (if only a single feature), or moved into a dedicated service

// History of this bug: When constant folding a long sequence of string concatentations, there is
// an intermediate constant value for every left-hand operand. So the total memory consumed to
// compute the whole concatenation was O(n^2). The compiler would simply perform this work and
// eventually run out of memory, simply crashing with no useful diagnostic. Later, the concatenation
// implementation was instrumented so it would detect when it was likely to run out of memory soon,
// and would instead report a diagnostic at the last step. This test was added to demonstrate that
// we produced a diagnostic. However, the compiler still consumed O(n^2) memory for the
// concatenation and this test used to consume so much memory that it would cause other tests running
// in parallel to fail because they might not have enough memory to succeed. So the test was
// disabled and eventually removed. The compiler would still crash with programs containing large
// string concatenations, so the underlying problem had not been addressed. Now we have revised the
// implementation of constant folding so that it requires O(n) memory. As a consequence this test now
// runs very quickly and does not consume gobs of memory.

// History of this bug: When constant folding a long sequence of string concatentations, there is
// an intermediate constant value for every left-hand operand. So the total memory consumed to
// compute the whole concatenation was O(n^2). The compiler would simply perform this work and
// eventually run out of memory, simply crashing with no useful diagnostic. Later, the concatenation
// implementation was instrumented so it would detect when it was likely to run out of memory soon,
// and would instead report a diagnostic at the last step. This test was added to demonstrate that
// we produced a diagnostic. However, the compiler still consumed O(n^2) memory for the
// concatenation and this test used to consume so much memory that it would cause other tests running
// in parallel to fail because they might not have enough memory to succeed. So the test was
// disabled and eventually removed. The compiler would still crash with programs containing large
// string concatenations, so the underlying problem had not been addressed. Now we have revised the
// implementation of constant folding so that it requires O(n) memory. As a consequence this test now
// runs very quickly and does not consume gobs of memory.

===
## Summary
The compiler produces the [Microsoft.Net.Compilers.Toolset NuPkg](https://www.nuget.org/packages/Microsoft.Net.Compilers.Toolset)
from all of Roslyn's main branches. When this NuPkg is installed it will
override the compiler that comes with MSBuild with the version from the branch
it was built in.
This package is meant to support the following scenarios:
1. Allows compiler team to provide rapid hot fixes to customers who hit a blocking
issue. This package can be installed until the fix is available in .NET SDK or
Visual Studio servicing.
1. Serves as a transport mechanism for the Roslyn binaries in the greater .NET
SDK build process.
1. Allows customers to conduct experiments on various Roslyn builds, many of
which aren't in an official shipping product yet.
This package is **not** meant to support using newer compiler versions in an
older version of MSBuild. For example using Microsoft.Net.Compilers.Toolset
3.5 (C# 8) inside MSBuild 15 is explicitly not a supported scenario.
Customers who want to use the compiler as a part of their supported build
infrastructure should use the [Visual Studio Build Tools SKU](https://docs.microsoft.com/en-us/visualstudio/install/workload-component-id-vs-build-tools?view=vs-2022])

## NuPkg Installation
To install the NuPgk run the following:
```cmd
> nuget install Microsoft.Net.Compilers.Toolset # Install C# and VB compilers
```
Daily NuGet builds of the project are also available in our [Azure DevOps feed](https://dev.azure.com/dnceng/public/_packaging?_a=feed&feed=dotnet-tools):

## Microsoft.Net.Compilers
The [Microsoft.Net.Compilers](https://www.nuget.org/packages/Microsoft.Net.Compilers)
NuPkg is deprecated. It is a .NET Desktop specific version of
Microsoft.Net.Compilers.Toolset and will not be produced anymore after the
3.6.0 release. The Microsoft.Net.Compilers.Toolset package is a drop in
replacement for it for all supported scenarios.
| Compiler Toolset NuPkgs
===
## Summary
The compiler produces the [Microsoft.Net.Compilers.Toolset NuPkg](https://www.nuget.org/packages/Microsoft.Net.Compilers.Toolset)
from all of Roslyn's main branches. When this NuPkg is installed it will
override the compiler that comes with MSBuild with the version from the branch
it was built in.
This package is meant to support the following scenarios:
1. Allows compiler team to provide rapid hot fixes to customers who hit a blocking
issue. This package can be installed until the fix is available in .NET SDK or
Visual Studio servicing.
1. Serves as a transport mechanism for the Roslyn binaries in the greater .NET
SDK build process.
1. Allows customers to conduct experiments on various Roslyn builds, many of
which aren't in an official shipping product yet.
This package is **not** meant to support using newer compiler versions in an
older version of MSBuild. For example using Microsoft.Net.Compilers.Toolset
3.5 (C# 8) inside MSBuild 15 is explicitly not a supported scenario.
Customers who want to use the compiler as a part of their supported build
infrastructure should use the [Visual Studio Build Tools SKU](https://docs.microsoft.com/en-us/visualstudio/install/workload-component-id-vs-build-tools?view=vs-2022])
) or [.NET SDK](https://dotnet.microsoft.com/download/visual-studio-sdks)

// params array. This is very efficient as the runtime can allocate a buffer for the string with exactly the correct length and
// make no intermediate allocations.
// 3. The WellKnownType DefaultInterpolatedStringHandler is available, and none of the interpolation holes contain an await expression.
// The builder is a ref struct, and we can guarantee the lifetime won't outlive the stack if the string doesn't contain any
// awaits, but if it does we cannot use it. This builder is the only way that ref structs can be directly used as interpolation
// hole components, which means that ref structs components and await expressions cannot be combined. It is already illegal for
// the user to use ref structs in an async method today, but if that were to ever change, this would still need to be respected.
// We also cannot use this method if the interpolated string appears within a catch filter, as the builder is disposable and we
// cannot put a try/finally inside a filter block.
// 4. The string is composed of more than 4 components that are all strings themselves. We can turn this into a single
// call to string.Concat. We prefer the builder over this because the builder can use pooling to avoid new allocations, while this
// call will need to allocate a param array.
// 5. The string has heterogeneous data and either InterpolatedStringHandler is unavailable, or one of the holes contains an await
// expression. This is turned into a call to string.Format.
//
// We need to do the determination of 1, 2, 3, or 4/5 up front, rather than in lowering, as it affects diagnostics (ref structs not being

/// It should be thought of a generalized way to apply type-pattern-matching and syntax-deconstruction in a uniform
/// fashion over the languages. Helpers in this type should only be one of the following forms:
/// <list type="bullet">
/// <item>
/// 'IsXXX' where 'XXX' exactly matches one of the same named syntax (node, token, trivia, list, etc.) constructs that
/// both C# and VB have. For example 'IsSimpleName' to correspond to C# and VB's SimpleNameSyntax node. These 'checking'
/// methods should never fail. For non leaf node types this should be implemented as a typecheck ('is' in C#, 'typeof ... is'
/// in VB). For leaf nodes, this should be implemented by deffering to <see cref="ISyntaxKinds"/> to check against the
/// raw kind of the node.
/// </item>
/// <item>
/// 'GetPartsOfXXX(SyntaxNode node, out SyntaxNode/SyntaxToken part1, ...)' where 'XXX' one of the same named Syntax constructs
/// that both C# and VB have, and where the returned parts correspond to the members those nodes have in common across the
/// languages. For example 'GetPartsOfQualifiedName(SyntaxNode node, out SyntaxNode left, out SyntaxToken dotToken, out SyntaxNode right)'
/// VB. These functions should throw if passed a node that the corresponding 'IsXXX' did not return <see langword="true"/> for.
/// For nodes that only have a single child, 'GetPartsOfXXX' is not not needed and can be replaced with the easier to use
/// 'GetXXXOfYYY' to get that single child.
/// </item>
/// <item>
/// 'GetXxxOfYYY' where 'XXX' matches the name of a property on a 'YYY' syntax construct that both C# and VB have. For
/// example 'GetExpressionOfMemberAccessExpression' corresponding to MemberAccessExpressionsyntax.Expression in both C# and
/// VB. These functions should throw if passed a node that the corresponding 'IsYYY' did not return <see langword="true"/> for.
/// For nodes that only have a single child, these functions can stay here. For nodes with multiple children, these should migrate
/// to <see cref="ISyntaxFactsExtensions"/> and be built off of 'GetPartsOfXXX'.
/// </item>
/// <item>
/// Absolutely trivial questions that relate to syntax and can be asked sensibly of each language. For example,
/// if certain constructs (like 'patterns') are supported in that language or not.
/// </item>
/// </list>
///
/// <para>Importantly, avoid:</para>
///
/// <list type="bullet">
/// <item>
/// Functions that attempt to blur the lines between similar constructs in the same language. For example, a QualifiedName
/// is not the same as a MemberAccessExpression (despite A.B being representable as either depending on context).
/// Features that need to handle both should make it clear that they are doing so, showing that they're doing the right
/// thing for the contexts each can arise in (for the above example in 'type' vs 'expression' contexts).
/// </item>
/// <item>
/// Functions which are effectively specific to a single feature are are just trying to find a place to place complex
/// feature logic in a place such that it can run over VB or C#. For example, a function to determine if a position
/// is on the 'header' of a node. a 'header' is a not a well defined syntax concept that can be trivially asked of
/// nodes in either language. It is an excapsulation of a feature (or set of features) level idea that should be in
/// its own dedicated service.
/// </item>
/// <item>
/// Functions that mutate or update syntax constructs for example 'WithXXX'. These should be on SyntaxGenerator or
/// some other feature specific service.
/// </item>
/// <item>
/// Functions that a single item when one language may allow for multiple. For example 'GetIdentifierOfVariableDeclarator'.
/// In VB a VariableDeclarator can itself have several names, so calling code must be written to check for that and handle
/// it apropriately. Functions like this make it seem like that doesn't need to be considered, easily allowing for bugs
/// to creep in.
/// </item>
/// <item>
/// Abbreviating or otherwise changing the names that C# and VB share here. For example use 'ObjectCreationExpression'
/// not 'ObjectCreation'. This prevents accidental duplication and keeps consistency with all members.
/// </item>
/// </list>
/// </summary>
/// <remarks>
/// Many helpers in this type currently violate the above 'dos' and 'do nots'. They should be removed and either
/// inlined directly into the feature that needs if (if only a single feature), or moved into a dedicated service

/// <list type="bullet">
/// <item>
/// 'IsXXX' where 'XXX' exactly matches one of the same named syntax (node, token, trivia, list, etc.) constructs that
/// both C# and VB have. For example 'IsSimpleName' to correspond to C# and VB's SimpleNameSyntax node. These 'checking'
/// methods should never fail. For non leaf node types this should be implemented as a typecheck ('is' in C#, 'typeof ... is'
/// in VB). For leaf nodes, this should be implemented by deffering to <see cref="ISyntaxKinds"/> to check against the
/// raw kind of the node.
/// </item>
/// <item>
/// 'GetPartsOfXXX(SyntaxNode node, out SyntaxNode/SyntaxToken part1, ...)' where 'XXX' one of the same named Syntax constructs
/// that both C# and VB have, and where the returned parts correspond to the members those nodes have in common across the
/// languages. For example 'GetPartsOfQualifiedName(SyntaxNode node, out SyntaxNode left, out SyntaxToken dotToken, out SyntaxNode right)'
/// VB. These functions should throw if passed a node that the corresponding 'IsXXX' did not return <see langword="true"/> for.
/// For nodes that only have a single child, 'GetPartsOfXXX' is not not needed and can be replaced with the easier to use
/// 'GetXXXOfYYY' to get that single child.
/// </item>
/// <item>
/// 'GetXxxOfYYY' where 'XXX' matches the name of a property on a 'YYY' syntax construct that both C# and VB have. For
/// example 'GetExpressionOfMemberAccessExpression' corresponding to MemberAccessExpressionsyntax.Expression in both C# and
/// VB. These functions should throw if passed a node that the corresponding 'IsYYY' did not return <see langword="true"/> for.
/// For nodes that only have a single child, these functions can stay here. For nodes with multiple children, these should migrate
/// to <see cref="ISyntaxFactsExtensions"/> and be built off of 'GetPartsOfXXX'.
/// </item>
/// <item>
/// Absolutely trivial questions that relate to syntax and can be asked sensibly of each language. For example,
/// if certain constructs (like 'patterns') are supported in that language or not.
/// </item>
/// </list>
///
/// <para>Importantly, avoid:</para>
///
/// <list type="bullet">
/// <item>
/// Functions that attempt to blur the lines between similar constructs in the same language. For example, a QualifiedName
/// is not the same as a MemberAccessExpression (despite A.B being representable as either depending on context).
/// Features that need to handle both should make it clear that they are doing so, showing that they're doing the right
/// thing for the contexts each can arise in (for the above example in 'type' vs 'expression' contexts).
/// </item>
/// <item>
/// Functions which are effectively specific to a single feature are are just trying to find a place to place complex
/// feature logic in a place such that it can run over VB or C#. For example, a function to determine if a position
/// is on the 'header' of a node. a 'header' is a not a well defined syntax concept that can be trivially asked of
/// nodes in either language. It is an excapsulation of a feature (or set of features) level idea that should be in
/// its own dedicated service.
/// </item>
/// <item>
/// Functions that mutate or update syntax constructs for example 'WithXXX'. These should be on SyntaxGenerator or
/// some other feature specific service.
/// </item>
/// <item>
/// Functions that a single item when one language may allow for multiple. For example 'GetIdentifierOfVariableDeclarator'.
/// In VB a VariableDeclarator can itself have several names, so calling code must be written to check for that and handle
/// it apropriately. Functions like this make it seem like that doesn't need to be considered, easily allowing for bugs
/// to creep in.
/// </item>
/// <item>
/// Abbreviating or otherwise changing the names that C# and VB share here. For example use 'ObjectCreationExpression'
/// not 'ObjectCreation'. This prevents accidental duplication and keeps consistency with all members.
