Describe the bug

When upgrading our project from net5.0 to net6.0 we have seen major regressions in build time. Our project (ASP.NET Core MVC with controllers and views) went from a build of ~19secs to ~1min 10secs. Builds were done in windows terminal (current channel) using dotnet build --clp:PerformanceSummary for all of these. Our outputs are below for what doesn't give away too much info publicly 😄

Expected Behavior

Not regress performance and developer productivity.

Steps To Reproduce

You can replicate an increase in build time by creating a new net5.0 'ASP.NET Core Web App' in VS2022 and then building that and creating a new net6.0 one and building that. This gives me a time of 1.72secs for net5.0 vs 2.95secs for net6.0.
