Sebastian recently reported a scenario where an operation in Visual Studio took an unreasonable amount of time (15minutes) on a large Unity project (477 individual csproj in the solution).

Sebastian was kind enough to reach out and share a way to reproduce the issue.

What's happening

When all the projects of a Visual Studio solution are in an “unloaded” state.
