Actually pass through --use-mono-runtime property

[directhex]

Closes: dotnet/source-build#4142

[tmds]

We used to pass this to all projects using (from release/8.0.1xx):

installer/src/SourceBuild/content/repo-projects/Directory.Build.props

Line 158 in 96079bf

<StandardSourceBuildArgs>$(StandardSourceBuildArgs) /p:SourceBuildUseMonoRuntime=$(SourceBuildUseMonoRuntime)</StandardSourceBuildArgs>

On the main branch there is now:

installer/src/SourceBuild/content/repo-projects/Directory.Build.props

Line 92 in a885953

<BuildArgs Condition="'$(SourceBuildUseMonoRuntime)' == 'true'">$(BuildArgs) /p:SourceBuildUseMonoRuntime=$(SourceBuildUseMonoRuntime)</BuildArgs>

Is this doing something different than before, so that this change is required?

[tmds]

If this is for making --usemonoruntime work when not specifying --source-build, then the fix may be to not make this BuildArgs assignment conditional on "'$(DotNetBuildSourceOnly)' == 'true'".

SourceBuildUseMonoRuntime affects other repos too (aspnetcore and installer).

[directhex]

Urgh, not sure how I missed the Directory.Build.Props handling of this.

[ViktorHofer]

If this property doesn't just affect source-build then the name is misleading and should be updated.

[directhex]

You're right, of course, but coordinating property renames across multiple repos is horrible.

Can you please file a tracking issue so that this doesn't get lost in /dev/null?
