Selecting VS 2019 compiler for DocFX generator

[pwcrickman]

I am using an older version of DocFx (2.56.x) with VS 2019. I have VS 2022 installed on my system. When I execute DocFx it uses VS 2022 as the inner compiler. How do I set the DocFx inner compiler to use VS 2019?

From the source code, it appears that DocFX uses MSBuildLocator, which in turn uses hostfxr_resolve_sdk2; so presumably a global.json file could be used to specify the .NET SDK version whose MSBuild you want to use.

Oh, "an older version", so running on .NET Framework… in that case, try running DocFX from Visual Studio Developer Command Prompt of the desired version, or setting the VSINSTALLDIR and VSCMD_VER environment variables manually.

I was able to run docfx command in VS Developer Command Prompt. How do I resolve this error:

[Failure] Msbuild failed when processing the file '<csproj path>' with message: The SDK 'Microsoft.NET.Sdk' specified could not be found.

The csproj and docfx.json file are targeting netcoreapp3.1
