+- Install Visual Studio (documented version: 17.12). You can install the necessary components in one of 3 ways:
   - Follow Microsoft's instructions for [importing a configuration](https://docs.microsoft.com/en-us/visualstudio/install/import-export-installation-configurations?view=vs-2022#import-a-configuration), and import the .vsconfig file located at the root of the solution.
   - Alternatively, you can open the ILSpy solution (ILSpy.sln) and Visual Studio will [prompt you to install the missing components](https://docs.microsoft.com/en-us/visualstudio/install/import-export-installation-configurations?view=vs-2022#automatically-install-missing-components).
   - Finally, you can manually install the necessary components via the Visual Studio Installer. The workloads/components are as follows:
-    - Workload ".NET Desktop Development". This workload includes the .NET Framework 4.8 SDK and the .NET Framework 4.7.2 targeting pack, as well as the [.NET 8.0 SDK](https://dotnet.microsoft.com/download/dotnet/8.0) (ILSpy.csproj targets .NET 8.0, but we have net472 projects too). _Note: The optional components of this workload are not required for ILSpy_

       - _The VC++ toolset is optional_; if present it is used for `editbin.exe` to modify the stack size used by ILSpy.exe from 1MB to 16MB, because the decompiler makes heavy use of recursion, where small stack sizes lead to problems in very complex methods.
