text: # Workshop (with examples in NServiceBus)
  
  ## Prerequisites
  
  - Windows 8.1 or Windows 10
  - Visual Studio 2017 or Visual Studio 2019
  
  **Please ensure you have prepared your machine well in advance of the workshop. Your time during the workshop is valuable, and we want to use it for learning, rather than setting up machines.**
  
  If you have any difficulty preparing your machine, or following this document, please raise an issue in this repository ASAP so that we can resolve the problem before the workshop begins.

  ## Preparing your machine for the workshop
  
  - [Install the pre-requisites](#install-the-pre-requisites)
  - [Get a copy of this repository](#get-a-copy-of-this-repository)
  - [Set up the databases](#set-up-the-databases)
  - [Build the exercise solutions](#build-the-exercise-solutions)
  
  NOTE: you can optionally also [prepare your machine in advance for the advanced exercises](#preparing-your-machine-for-the-advanced-exercises).
  
  ### Install the pre-requisites
  
  To complete the exercises, you require a Windows machine and Visual Studio. You must be using a Windows client edition, such as Windows 10, rather than a server edition, such as Windows Server 2016. The Particular Platform Installer does not support server editions of Windows.
  
  Although specific versions of the pre-requisites are mentioned here, later versions may also work. When we confirm that the exercises work with later versions of the pre-requisites, we will update these instructions to refer to those later versions.
  
  #### Visual Studio
  
  Install [Visual Studio](https://www.visualstudio.com) (Preferably 2019, but 2017 is also possible. Either Community, Professional, or Enterprise) with the following workloads:
  
  - .NET desktop development
  - ASP.NET and web development
  
  If you are not running the latest version of Visual Studio 2017, you may need to install the .NET Core SDK seperately. Install [version 2.0.3 or newer](https://www.microsoft.com/net/download/all).
  
  #### LocalDB
  
  - Visit the [SQL Server 2017 Express Edition](https://www.microsoft.com/en-us/download/details.aspx?id=55994) website.
  - Scroll down to the title "Choose which SQL Server 2017 Express to download"
  - Select "SQL Server 2017 Express LocalDB"
  - Download and run `SQLServer2017-SSEI-Expr.exe` from the download location
  - In the installer, select the "Download Media" option
  - Select "LocalDB", let the installer download it and the press the "Open folder" button
  - Run `SqlLocalDB.msi`
  
  #### SQLCMD
  
  - Install [ODBC Driver 13.1 for SQL Server](https://www.microsoft.com/en-us/download/details.aspx?id=53339) (this is a pre-requisite of SQLCMD).
  - Install [Command Line Utilities 14.0 for SQL Server](https://www.microsoft.com/en-us/download/details.aspx?id=53591) (often referred to as "SQLCMD").
  
  ### Get a copy of this repository
  
  Clone or download this repo. If you're downloading a zip copy of the repo, ensure the zip file is unblocked before decompressing it:
  
  - Right-click on the downloaded copy
  - Click "Properties"
  - On the "General" properties page, check the "Unblock" checkbox
  - Click "OK"
  
  ### Set up the databases
  
  Open an **elevated** command prompt, navigate to your copy of this repo, and run:
  
  ```Batchfile
  powershell -NoProfile -ExecutionPolicy unrestricted -File exercises\scripts\Setup-LocalDBInstance.ps1
  ```
  
  When you no longer need to run the exercises, you may optionally run `Teardown-LocalDBInstance.ps1`.
  
  ### Build the exercise solutions
  
  The exercises are contained in eight Visual Studio solutions under [exercises](exercises). All the solutions require NuGet package restore. This may be possible at the workshop venue (you can verify with the workshop organizers if internet access is available at the venue) but to ensure you can build the solutions during the workshop, we recommend you restore all NuGet packages and build all the solutions before the workshop starts. The simplest way to do this is to open a command prompt, navigate to your copy of this repo, and run `.\build.cmd exercises`. (For a full list of build targets, run `.\build.cmd -T`, or `.\build.cmd -h` for help.)
  
  **You can safely ignore any compiler warnings**.
  
  TIP: For a faster build, specify the `--parallel` (or `-p`) option to build all the exercise solutions in parallel. This can result in a 50% reduction in build time! Bear in mind that the console output from all the solutions will be mixed together, which could make it more difficult to diagnose failures. If the build does fail, it may be best to re-run it without the `--parallel` option before diagnosing the problem.
  
  ## Running the exercise solutions
  
  Before running an exercise solution, you need to set the startup projects.
  
  One way to do this is to use the *SwitchStartupProject* Visual Studio extension. After installing the extension, open the exercise solution and choose the "Exercise" startup configuration.
  
  - [SwitchStartupProject](https://marketplace.visualstudio.com/items?itemName=vs-publisher-141975.SwitchStartupProjectforVS2017) for Visual Studio 2017
  - [SwitchStartupProject](https://marketplace.visualstudio.com/items?itemName=vs-publisher-141975.SwitchStartupProjectForVS2019) for Visual Studio 2019
  
  The startup projects are also listed in the instructions for each exercise. If you need to, you can configure them manually:
  
  - In Visual Studio, right click the solution in the Solution Explorer
  - Click "Properties"
  - Ensure that, in the left hand pane, "Common Properties", "Start Project" is selected.
  - Select the "Multiple startup projects" radio button
  - Set the "Action" for each project listed in the instructions for the exercise to "Start".
  
  To run an exercise solution, simply press <kbd>F5</kbd> in Visual Studio. The exercise solution will now be running and fully functional.
  
  ### Note
  
  The solutions contain single page applications (SPAs) and use `IIS Express`. To prevent caching issues, before switching to another exercise:
  
  - Ensure that `IIS Express` is shut down
  - Clear the browser cache (or disable it entirely). Alternatively, the cache can cleared by refreshing the page using <kbd>Shift</kbd>+<kbd>F5</kbd> or <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>R</kbd> in some browsers.
  - When running a solution, the wrong page is sometimes displayed in the browser. Either:
    - Ensure all HTML template files are closed when the application is run, or:
    - Manually change the browser address to the root URL.
  
  ## Preparing your machine for the advanced exercises
  
  If you completed all the standard exercises, first of all, well done!
  
  You can now attempt the advanced exercises. Don't worry if you don't manage to start or complete the advanced exercises during the workshop. You can also attempt them after the workshop is finished. If you have questions, you can ask them during the workshop or in our [community discussion forum](https://discuss.particular.net/).
  
  It is likely that you will have to read documentation for the Particular Service Platform to finish the advanced exercises. Links to documentation will be provided.
  
  To complete the advanced exercises, you first need to install the rest of the Particular Service Platform:
  
  - ServicePulse: a web app which monitors your endpoints.
  - ServiceInsight: a desktop app which visualises the flow of messages within and between endpoints in detail.
  - ServiceControl: a Windows service which collects the data that drives ServicePulse and ServiceInsight.
  
  ### Run the Particular Platform Installer
  
  Run the [Particular Platform Installer](https://particular.net/start-platform-download) again, selecting ServiceControl, ServiceInsight, and ServicePulse.
  
  NOTE: When you install ServicePulse, you may see two warnings about not being able to connect to ServiceControl. In both cases, click `Yes` to proceed with the installation. These warnings appear because, although ServiceControl has been installed, no instances have yet been created.
  
  NOTE: If you are using Microsoft Edge, see [the FAQ](#how-do-i-download-the-particular-platform-installer-with-microsoft-edge).
  
  When installation has completed, click "Start ServiceControl Management".
  
  You may now close the Particular Service Platform Installation window.
  
  ### Add a ServiceControl Instance
  
  In the ServiceControl Management window, click "New" and then "Add ServiceControl and Audit Instances".
  
  In the settings for the new instance, there are two choices you must make:
  
  - "Transport": choose "MSMQ".
  - "Audit forwarding": choose "Off".
  
  All other settings should be left with their default values.
  
  Click "Add".
  
  After the instance has been added, make a note of the name of the instance. This will usually be "Particular.ServiceControl".
  
  ### Add a ServiceControl monitoring Instance
  
  In the ServiceControl Management window, click "New" and then "Add Monitoring instance".
  
  In the settings for the new instance, there is one choice you must make:
  
  - "Transport": choose "MSMQ".
  
  All other settings should be left with their default values.
  
  Click "Add".
  
  After the instance has been added, make a note of the name of the instance. This will usually be "Particular.Monitoring".
  
  You may now close the ServiceControl Management window.
  
  You're now ready to attempt the advanced exercises!
  
  ## Demos
  
  ### ASP.NET Core UI composition
  
  The [`asp-net-core` solution](demos/asp-net-core) demonstrates the use of ASP.NET Core to compose a UI with data from several services.
  
  ### ServicePulse monitoring & recovery
  
  The [self contained platform demo](https://docs.particular.net/tutorials/monitoring-demo/) includes ServicePulse, ServiceControl, ServiceControl Monitoring and a few endpoints to demonstrate monitoring and recovery.
  
  ## FAQ
  
  If the answer to your question is not listed here, consult your on-site trainer.
  
  ### How can I clear the orders list?
  
  The simplest method is to reset all the databases (see below). Bear in mind that this will reset _all the databases_ for _all the exercises_.
  
  Alternatively, if you want to clear the orders list for a specific exercise, connect to the LocalDB instance, and either pick out and run the `drop` and `create` statements for that exercise from the scripts, or manually delete, or truncate, the tables that need to be cleared.
  
  To reset all the databases:
  
  Connect to the instance and run `Teardown-Databases.sql` followed by `Setup-Databases.sql`, both located in the [exercises/scripts](exercises/scripts) folder.
  
  ### Can I use Windows 7?
  
  Yes. However, Visual Studio 2017 comes with SQL Server 2016 LocalDB, which is not compatible with Windows 7. Instead, you will need to install [SQL Server 2014 LocalDB](https://www.microsoft.com/en-us/download/details.aspx?id=42299). When prompted to choose which file to download, choose either the 64-bit or 32-bit version of `SqlLocalDB.msi`, depending on [your Windows installation](https://support.microsoft.com/en-gb/help/15056/windows-7-32-64-bit-faq).
  
  ### How do I download the Particular Platform Installer with Microsoft Edge?
  
  When you attempt to download the installer, you may be presented with this message:
  
  ![download prompt](img/platform-installer-on-edge/download-prompt.png?raw=true)
  
  If so, click on "View Downloads" to show the "Downloads" window:
