Repro Steps & Context

Firstly, the regression required you use a version of VS with this dotnet/project-system change: dotnet/project-system#9470

Second, it might not have a user observable regression. It's a perf regression only. If it's observable, then the timestamp on the project.assets.json file in the obj folder will change, even if the contents do not.

But the repro steps are to open a solution with SDK style projects, and then "rebuild" (not just "build) the solution. In NuGet.Commands.dll's RestoreCommand.CommitAsync, it will think the assets file has changed, but it should not have.
