Our CI builds fails because of bug NuGet/Home#12373. It is fixed in NuGet/NuGet.Client#5010. We are waiting for it to flow to CI machines. Meanwhile this PR applies a workaround. Note: This PR needs to be reverted once it happens.

Note: This PR needs to be reverted once it happens. --------- Co-authored-by: AR-May <[email protected]> * Use AutoResetEvent as oppose to ManualResetEventSlim (#8575) Summary Customer, mainly internal like XStore, with huge repos, using msbuild /graph /bl on powerful development and build computers, might experience 15x plus regression in evaluation time. It has been identified as performance bug in our logging event pub/sub mechanism. When ingest queue reaches its bound, at .net472 ManualResetEventSlim causes way too many thread.Yields flooding the system with thread context switches. This hypothesis has been verified by PerfMon perfcounter System.ContextSwitches. Alhougt counterintuitive, AutoResetEvent , ManualResetEvent or even SpinLocking produced better behavior and with those the issue no longer reproduce. Customer Impact In case of XStore it was about 7 minutes in build time. Regression? Yes, introduced in VS 17.4. Testing Manual validation by @rokonec and automated tests. Using local repro to verify changes has fixed it. Risk Low Note It effect only VS MSBuild.exe. In dotnet build ManualResetEventSlim works better. --------- Co-authored-by: Roman Konecny <[email protected]> Co-authored-by: AR-May <[email protected]>
