When a renamed project has dependents, Visual Studio keeps a file handle on each referencing .csproj (workspace, file watchers, design-time build). Writing through XmlDocument.Save would frequently fail with 'The process cannot access the file because it is being used by another process', leaving the rename in a partially applied state. Each referencing project is now unloaded via IVsSolution4.UnloadProject, rewritten, and reloaded in a finally block. If the unload cannot be performed (no GUID, service missing, HRESULT failure), we fall back to the previous direct-save behavior so this change never regresses.
