Start by reproducing the problem on Windows with C# extension 2.140.9 and VS Code 1.127.0, using the supplied C# log as the initial evidence. Determine which reported diagnostic or code-action failures are the actual user-facing problem and add reproducible steps and expected behavior. Done requires a confirmed cause and a verified fix.
