Enabling CORS in a .NET Core Server-Side Application
Tags: core, net, cors, csharp
Published: 2023-12-30 19:00:23

## Step 1: Install the Microsoft.AspNetCore.Cors NuGet Package


Open your .NET Core project in Visual Studio or your preferred code editor. In the Package Manager Console or the terminal, run the following command to install the CORS package:

```bash
dotnet add package Microsoft.AspNetCore.Cors
```

Alternatively, you can use the NuGet Package Manager in Visual Studio to search for and install the package.

## Step 2: Configure CORS in Startup.cs

Open the Startup.cs file in your project. In the ConfigureServices method, add the CORS policy configuration using the AddCors method:

```csharp
public void ConfigureServices(IServiceCollection services)
{
    // Other ConfigureServices configurations...

    services.AddCors(options =>
    {
        options.AddPolicy("AllowSpecificOrigin",
            builder =>
            {
                builder.WithOrigins("http://example.com") // Add your client-side application's origin here
                       .AllowAnyHeader()
                       .AllowAnyMethod();
            });
    });

    // More ConfigureServices configurations...
}
```

Make sure to replace "http://example.com" with the actual origin of your client-side application. If you want to allow any origin, you can use builder.AllowAnyOrigin() instead.

## Step 3: Apply CORS Middleware in the Configure Method

In the Configure method of Startup.cs, add the CORS middleware using the UseCors method:

```csharp
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    // Other Configure configurations...

    app.UseCors("AllowSpecificOrigin");

    // More Configure configurations...
}
```

This middleware should be placed before any other middleware or routing configurations.

## Step 4: Run and Test Your Application

Now that CORS is configured, run your .NET Core application. Make requests from your client-side application to the server and verify that CORS is working as expected.

Additional Tips:
For development purposes, you might want to install the Microsoft.AspNetCore.Mvc.NewtonsoftJson NuGet package and configure JSON serialization to allow circular references using AddNewtonsoftJson in the ConfigureServices method.

```csharp
services.AddMvc().AddNewtonsoftJson(options =>
{
    options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
});
```

Remember to handle CORS settings carefully in a production environment, and only allow specific origins that are necessary for security reasons.

Let AI generate Pull Requests from your GitHub issues!
Tags: githubactions, ai, automation, llm
Published: 2023-12-30 17:53:27



It's time we all stop wasting time on those small and medium-sized tasks that make our day miserable. Create small issues and let AI deal with them.

My (probably) last gift of 2023 for you all is a GitHub action + workflow which generates Pull Requests from your GitHub issues!

Check them out:
- [aider-github-action](https://github.com/mirrajabi/aider-github-action)
- [aider-github-workflows](https://github.com/mirrajabi/aider-github-workflows)

[Aider](https://aider.chat/) is a coding assistant that handles all the prompting and communication with OpenAI.

## Getting started

Follow [the instruction's to add the 'aider-issue-to-pr' workflow to your project](https://github.com/mirrajabi/aider-github-workflows/blob/main/docs/issue-to-pr.md).

And that's all the setup you need to do!

Now let's test things out.

1. Create a GitHub issue and assign `aider` label to it.
1. An action automatically runs when the label is added and commits requested changes to the source code on a new branch. Lastly, it creates a pull-request for you to review.
1. You review the code, possibly tweak it and merge it!

## Example

I've created an example repo to demonstrate the full flow. See the [readme of this repo](https://github.com/mirrajabi/aider-github-workflows-test)

## How does it work under the hood?

[aider-github-action](https://github.com/mirrajabi/aider-github-action) runs aider in a container and runs a single prompt on it, commits, and pushes its changes on a branch that you pass to it as an input.

[aider-github-workflows](https://github.com/mirrajabi/aider-github-workflows) uses [aider-github-action](https://github.com/mirrajabi/aider-github-action) to facilitate the creation of pull requests and new branches.

For more information see the documentation and the source code of these repos. They are currently very small and simple to review!

## How much OpenAI credit does it cost?

I was positively surprised when I first started using [Aider](https://aider.chat/)! I had 10 chats about some quite large changes and it only cost me less than $0.5 even though I was using the latest GPT-4 Turbo model (`gpt-4-1106-preview`). Aider optimises the prompts and only [works with diffs rather than generating whole files](https://aider.chat/docs/unified-diffs.html). It also [sends a map of your project](https://aider.chat/docs/repomap.html) to GPT instead of whole files. All of these nice features make it a great tool to use on larger code bases with really low cost.


## Future of the project

I'm pretty sure GitHub will very soon make their own better version of "Issue to PR" tool available to those with either a GitHub copilot or Pro plans but until then, I think it's nice to have this open-source alternative.

Favourite Tech Startup Trio: MVP, PoC, and Prototype – Crafting Your Startup Journey
Tags: startup, tutorial, productivity, career
Published: 2023-12-30 17:41:37

Good morning my dear tech enthusiasts! Did you ever wonder about the difference between an MVP, PoC, and a Prototype? I mean, they're all the same... right? Yes, but not quite..

_I bet many of you have been thinking about creating something of your own, and this guide may be the first step towards that beginning._ But before we dive in, let's remember that each of these has a specific goal, and the results are always vary. Additionally, as we explore these concepts, we'll also uncover the essential steps to build your own successful startup, guiding you from idea to execution.

### PoC (Proof of Concept)

Think of this as the "baby step" of the tech world. It tests just one specific aspect. Imagine you're baking and you're testing if the new sugar you bought actually sweetens. The result? Not a cake, but an understanding of that sugar. In tech terms, it's an architectural or analytical artifact. Outcome? Insight and understanding, but not a complete product.

### Prototype

So you've tested the sugar and now you're testing flour, eggs, and other ingredients. But still no cake. This is what a prototype does. It tests multiple aspects but doesn't give you a full-fledged product. Outcome? A clearer vision of how different components might work together.

### MVP (Minimum Viable Product)

Ah, now we're talking! This is where you get a basic, no-frills cake. It might not have the fancy icing or decorations, but hey, it's still a cake. An MVP isn't about analysis but actual implementation. It's a real, tangible product built based on upper concepts. Outcome? A functional product that users can interact with.

In conclusion, only the MVP emerges as a real, hands-on product. PoC and Prototype take a step back, acting as the foundational blueprints that yeild the architectural or analytical artifacts.

## The Startup Path from Scratch to MVP

Let's see how a typical startup journey unfolds from the initial concept to the development of a Minimum Viable Product (MVP):

And there you have it, tech enthusiasts! We've just scratched the surface of the journey from PoC to Prototype, and ultimately to MVP. Each step is a critical part of transforming an idea into a concrete product. But the insights don't end here.

👉 **Curious to know the full plan and story?** Dive deeper into the fascinating world of tech startups on my blog. I've got more detailed insights, practical tips, and inspiring stories waiting for you. Whether you're an aspiring entrepreneur or a tech enthusiast, you'll find a treasure trove of information.

using statement in C#
Published: 2023-12-30 16:40:01

The `using` statement in C# serves two primary purposes:

**1. Resource Management:**
   - One of the main purposes of the `using` statement is to manage resources, especially objects that implement the `IDisposable` interface. Objects that implement `IDisposable` typically represent unmanaged resources, such as file handles, database connections, or network connections.
   - The `using` statement ensures that the `Dispose` method of the object is called when the block is exited, whether it's exited normally or due to an exception. This helps in releasing resources promptly and efficiently.

   Example with `FileStream`:
```csharp
   using (FileStream fileStream = new FileStream("example.txt", FileMode.Open))
   {
       // Use the fileStream object
   } // Dispose method of fileStream is automatically called when exiting the block
```

**2. Namespace Aliasing:**
   - The `using` statement is also used for namespace aliasing. It allows you to create an alias for a namespace to simplify the code and avoid naming conflicts.
   - This is especially useful when you have multiple namespaces with the same class or type names, and it helps in making the code more readable.

   Example:
```csharp
   using System;
   using Alias = AnotherNamespace.SomeClass;

   namespace MyNamespace
   {
       class Program
       {
           static void Main()
           {
               AnotherNamespace.SomeClass obj1 = new AnotherNamespace.SomeClass();
               Alias obj2 = new Alias(); // Using the alias
           }
       }
   }
```
In summary, the `using` statement in C# is crucial for effective resource management by automatically calling the `Dispose` method of `IDisposable` objects and for namespace aliasing to simplify code when dealing with multiple namespaces.

Hooked Book #8 - Habit testing
Tags: design, ethic, books, resume
Published: 2023-12-30 15:15:00

_Building a habit-forming product is an iterative process and requires user-behavior analysis and continuous experimentation._

It is a process inspired by the “build, measure, learn” methodology championed by the lean start-up movement. **Habit testing** offers insights and actionable data to inform the design of habit forming products.

The are three steps: Identify, codify and modify.

**Identify** Who are the product’s habitual users? Define what it means to be a devoted user and how often should one use your product.

**Codify** Your are looking for a Habit Path. A series or similar actions shared by your more loyal users.

**Modify** Tracking users by cohort and comparing their activity with that of habitual users should guide how products evolve and improve.
