Summary

Test Failure

The recent PR that added .lscache to the .gitignore file. We have a test that runs against the .gitignore file. This test did not run in the PR because CI didn't run in the PR. This PR addresses the test failure and adds the template_feed folder as a folder that is monitored for changes so that CI runs appropriately.

Build Failure 1 (consistent)

For the second PR, it was causing a build error.

##[error].dotnet\sdk\11.0.100-preview.3.26170.106\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(266,5): error NETSDK1047: (NETCORE_ENGINEERING_TELEMETRY=Build) Assets file 'D:\a\_work\1\s\artifacts\obj\dotnet-aot\project.assets.json' doesn't have a target for 'net11.0/win-x64'. Ensure that restore has run and that you have included 'net11.0' in the TargetFrameworks for your project. You may also need to include 'win-x64' in your project's RuntimeIdentifiers.

I tried to add TargetFramework=$(SdkTargetFramework), but that did not seem to fix the issue. Instead, I've just set the target to no longer run since it is not critical for any SDK functionality yet.

Build Failure 2 (inconsistent)

There was an inconsistent build failure happening.

##[error].dotnet/sdk/11.0.100-preview.3.26170.106/Microsoft.Common.CurrentVersion.targets(4917,5): error MSB3894: (NETCORE_ENGINEERING_TELEMETRY=Build) Got System.IO.IOException: The process cannot access the file '/Users/runner/work/1/s/artifacts/obj/Microsoft.TemplateEngine.Orchestrator.RunnableProjects/Release/net10.0/Microsoft.TemplateEngine.Orchestrator.RunnableProjects.dll' because it is being used by another process.

Had Copilot take a look. It realized there is a pattern to including projects in the dotnet.csproj. The recently migrated TemplateEngine project, Microsoft.TemplateEngine.Orchestrator.RunnableProjects, did not follow this pattern. It seems GlobalPropertiesToRemove="PublishDir" was missing, so that has been added to the project reference.
