…ed builds inside Visual Studio Work towards [AB#1337109](https://devdiv.visualstudio.com/DevDiv/_workitems/edit/1337109) For builds which are indirectly triggered inside Visual Studio from commands such as 'Run Tests' or 'Start Debugging', we implicitly skip analyzers to speed up these builds. Such builds will set a special property `IsIndirectlyTriggeredBuildInsideVisualStudio` to `true`, which guards the implicit skip analyzers logic. We display a special message to inform the users about us implicitly skipping analyzers to speed up the build. To enable MSBuild's incremental build logic and project system's fast-upto-date check logic to work correctly, we create/touch a special semaphore file to indicate the time stamp for last build with skipAnalyzers flag. This semaphore file is passed as a custom additional file input to builds without skipAnalyzers flag to ensure correct incremental builds. Additionally, we pass this file as an 'UpToDateCheckInput' item for project system's fast-upto-date check.
How about: IsImplicitlyTriggeredBuild? I'm not sure why we'd need to say it was visual studio, and I imagine this being useful for other hosts. |

That sounds reasonable, I'll update the naming. |

Restrict the functionality added in dotnet#54143 to only kick in for SDK style projects. This feature needs work in the project system for upto-date check to work correctly, and we are currently only commited to doing this work for CPS/SDK style projects.

…ed builds inside Visual Studio
Work towards AB#1337109
Overview
For builds which are implicitly triggered inside Visual Studio from commands such as 'Run Tests' or 'Start Debugging', we implicitly skip analyzers to speed up these builds.
Such builds will set a special property
IsImplicitlyTriggeredBuildtotrue, which guards the implicit skip analyzers logic. We display a special message to inform the users about us implicitly skipping analyzers to speed up the build. Note this message was provided to us by the UX team.To enable MSBuild's incremental build logic and project system's fast-upto-date check logic to work correctly, we create/touch a special semaphore file to indicate the time stamp for last build with skipAnalyzers flag. This semaphore file is passed as a custom additional file input to builds without skipAnalyzers flag to ensure correct incremental builds. Additionally, we pass this file as an 'UpToDateCheckInput' item for project system's fast-upto-date check.
Testing
AB#1337109 requires few more WIP PRs to go through to work end-to-end:
IsImplicitlyTriggeredBuildtotruefor builds indirectly triggered from these commands. I am working on these changes.I was able to locally build bits with both the above changes + changes from this PR and verify end-to-end functioning of this feature for Run Tests/Debug Tests command. Demo provided below.
