add support for dotnet watch run

I would love to see my scss files recompiled when dotnet watch --project myproject.csproj run, just like my typescript files.

Typescript is intergrated into msbuild using following reference:

<PackageReference Include="Microsoft.TypeScript.MSBuild" Version="4.5.2">

Now when I change any typescript file, it is recompiled and the output javascript is hot reloaded in my browser event without reloading a page.

BTW, I also like how typescript automatically discovers tsconfig files in my solution.

As far as I know, this is already possible and no change to this tool needs to be made. See the section on dotnet watch in the project's README.md:

https://github.com/excubo-ag/WebCompiler#compile-on-save-dotnet-watch

Please try that as a starting point and let me know if that section needs changes (I am personally not using dotnet watch at all).

Thanks

@stefanloerwald:
I need to run dotnet watch tool run webcompiler as a separate process in order to watch changes. And this command must be executed from exact directory to make relative paths work with --files, which is not very convenient.

following changes to csproj only compiles once:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
  </PropertyGroup>

 <Target Name="ToolRestore" BeforeTargets="PreBuildEvent">
      <Exec Command="dotnet tool restore" StandardOutputImportance="high" />
  </Target>

  <Target Name="PreBuild" AfterTargets="ToolRestore">
      <Exec Command="dotnet webcompiler -c webcompilerconfiguration.json  -f webcompilerfiles.conf" StandardOutputImportance="high" />
  </Target>

  <ItemGroup>
    <Watch Include="**\*.scss" />
  </ItemGroup>

When I change scss, the browser is reloaded (it shouldn't), but the compiler is not invoked. At least in .NET 6

I think in .NET 5 it triggered complete rebuild - not just scss.

Notice that Microsoft.TypeScript.MSBuild rebuilds only .ts files and it does incremental build
