Run a program directly after building in VS Code

Whenever I have a program that is just a generator of some kind I like to have that program execute directly after having built the program successfully. I'm going to show how to run the program via the dotnet cli but this trick can easily be applied to regular .NET programs or any program which is built using MSBuild.

Add the following to your csproj file:

<Target Name="ExecuteAfterBuild" AfterTargets="AfterBuild" Condition=" $(ExecuteAfterBuild) == true ">
    <Exec WorkingDirectory="$(OutputPath)" Command="dotnet $(AssemblyName).dll" />

This instructs MSBuild to execute the dotnet cli in the output directory of the assembly if the property ExecuteAfterBuild is set to true. This can be accomplished via the dotnet cli:

dotnet build MyProj.csproj -p:ExecuteAfterBuild=true

Or if you're using VS Code you can set it as a parameter in your tasks.json:

    "version": "2.0.0",
    "tasks": [
            "label": "generate",
            "group": "build",
            "command": "dotnet",
            "type": "process",
            "args": [
            "problemMatcher": "$msCompile"

Then you can use the build shortcut Ctrl + Shift + B to build your project and execute it directly.
