For our Visual Studio Code extension, we implemented a debug adapter for our Unity debugger.

Part of the job is translating data structures from our debugger (say a UnityThread), to a DAP Thread. We're using a library that uses List<T> to represent collections.

I originally wrote:

UnityThread[] threads = ...;
List<DAPThread> dapThreads = threads.Select(CreateDAPThread).ToList();

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.
