[filzrev]

This PR intended to fix #3191.

What's changed in this PR

1. Cherry picks other PR commits

Following PR contents are included

• chore: Add validator to check .NET SDK as minimum requirements #3194
• feat: add custom props/targets to customize project build #3195

2. Remove DllGatherer related logics

After this PR changes, DllGatherer logics seems not be needed.
So I've removed DllGatherer related logics.

3. Add settings for Autogenerated project.

Modify BenchmarkDotNet.Build.props.txt template.
And enable following settings for Autogenerated project.

• OutputPath
• PublishDir

4. Cleanup DotNetCliCommand.cs logics.

Previously, --output and -p:PublishDir command line parameters are used.
These settings are handled as MSBuild Global property and that causing DoubleWrite Issues.

So this PR move these settings to Autogenerated.csproj level.
other projects build outputs are placed under .artifacts directory.

4. Other Changes

1. Remove ErrorOnDuplicatePublishOutputFiles settings.
2. Add XmlDocument.SaveAsync helper method for netstandard2.0

I've re-enable <ErrorOnDuplicatePublishOutputFiles>false</ErrorOnDuplicatePublishOutputFiles> setting for WASM project.

Because it cause following errors for xunit.runner.visualstudio package related DLLs.

NETSDK1152: Found multiple publish output files with the same relative path

It seems occurred because xunit.runner.visualstudio package reference has <PrivateAssets>all</PrivateAssets> setting.

Wasm related CI tests are still failed when using ForcedNoDependenciesForIntegrationTests: false setting.

It seems that xUnit v2 is incompatible with wasm. It's probably fixed by #3232.

[filzrev]

Wasm related CI tests are still failed when using ForcedNoDependenciesForIntegrationTests: false setting.

This issue is caused commit 7f18102 is not pushed to target CI branch.

And I've added following commits to avoid issue when using ForcedNoDependenciesForIntegrationTests=false

• 75973bf (Increase timeout from 1 min to 5 min to avoid timeout)
• 20fc0fe (Increase job timeout to 720 minutes to avoid job timeout(Default: 360 minutes))
  (This setting is not works on GitHub Actions hosted runner. and timeout at 360 min)

[filzrev]

By changing some settings.
It pass CI with ForcedNoDependenciesForIntegrationTests=false setting.

CI: https://github.com/filzrev/BenchmarkDotNet/actions/runs/32571372114/workflow
(windows-latest CI is cancelled because it execution time overs 360 minutes (GitHub Actions hosted-runner limitation))
