Distributing Debugger visualizer packages

Question

I have a developed a few Debugger visualizer packages using the new approach with DebuggerVisualizerProvider and VisualStudioContribution as seen here: https://learn.microsoft.com/en-us/visualstudio/extensibility/visualstudio.extensibility/debugger-visualizer/debugger-visualizers?view=vs-2022. One visualizer that I already have on the Marketplace is here: https://github.com/elmahio/ExceptionVisualizer. I noticed in recent versions of Visual Studio 2022, my debug visualizer no longer shows up. I don't know exactly which minor version did this, but it worked back when I first published that extension.

I think I read somewhere that the new debug visualizer cannot be distributed as Vsixs on the marketplace. But it was working fine back then to add a new class library and include a source.extension.vsixmanifest file. The project type needed a special Sdk like this:

<Project Sdk="Microsoft.VisualStudio.Sdk.Build/17.5.4065">

When installing the visualizer linked above from the Marketplace, the visualizer no longer shows up during debugging. What could be the cause and is there any fix for distributing visualizer through the marketplace? If not, how do other people install them?

Hi @Thomas Ardal, 

Welcome to Microsoft Q&A! 

For Exception Visualizer extension, it is in Preview and owned by visualizer author. If you have any issues with the visualizer, you need to directly contact the visualizer author. 

Besides, if you have issue with custom Debugger Visualizers failing to load, you can see the similar issue. It is a known issue and will be fixed in VS 2022 version 17.12 Preview 2. Thanks for your understanding.

Sincerely,

Anna
