Resolve code issues in live apps running in Azure Kubernetes Services with the Snapshot Debugger

Snapshot Debugger is built for production so you can set Snappoints and Logpoints in code, like debugger breakpoints and tracepoints.

Introducing Time Travel Debugging for Visual Studio Enterprise 2019

The Time Travel Debugging (TTD) preview in Visual Studio Enterprise 2019 provides the ability to record a Web app running on a Azure Virtual Machine (VM) and then accurately reconstruct and replay the execution path. TTD integrates with our Snapshot Debugger offering and allows you to rewind and replay each line of code however many times you want, helping you isolate and identify problems that might only occur in production environments.
