About this tag
The c# diagnostics tag on WindowsForum.com covers practical techniques for investigating .NET application problems while they are still happening. A recent discussion looks at a C# thread-pool watcher that captures memory dumps after delays on Windows and Linux, using MiniDumpWriteDump on Windows and the runtime's createdump utility on Linux. The focus is on collecting evidence from an unresponsive process before a developer has to reproduce the fault, and on the trade-offs that come with doing so in production, including trigger conditions, permissions, sensitive data in dumps, and handling collection failures.
