Real questions. Useful conversations. Find the people who know your stack.
When Visual Studio Test Explorer fails to discover .NET unit tests, the cause is usually a workload, adapter, platform, or cache mismatch. Follow ordered checks to isolate and fix the issue.
Learn how to configure and use Hot Reload in Visual Studio to apply C# code changes to running applications without restarting the debugger.
Stop guessing why your .NET app is crashing with OutOfMemoryExceptions. Learn how to use Visual Studio's Diagnostic Tools to capture memory snapshots and find the root references causing leaks.
Hot Reload in Visual Studio lets you apply code edits to a running .NET debug session without restarting. Use it as a default inner-loop practice for UI and small logic tweaks, but check supported edits and verify with the Output window to avoid false confidence.
A decision guide for rolling out C# nullable reference types in an existing Visual Studio solution: compare enable vs warnings vs per-file modes, then implement and validate a warnings-first migration.
Code Lens brings test results, commit history, and reference counts into the editor margin, but requires configuration and has edition and performance caveats.
Hot Reload applies edits to a running .NET process without a restart. Here is how to set it up, verify the process did not restart, and recover from rejected edits.
CodeLens puts reference counts, Git authorship, and test status directly above your methods in Visual Studio. Used as a decision filter before refactoring, it tells you the blast radius of a change without leaving the editor.
MSBuild incremental builds skip targets whose outputs are newer than their inputs. Learn how the timestamp check works, what silently breaks it, and how to verify only changed projects recompile.
