UI unresponsiveness message shows in our custom extension

Question

installed our custom extensions like project template in VS, created project from that extension. After creation of project the report message on top "Visual Studio Stopped responding for 9 seconds. disabling the custom extension it might help "

Also shows in  UnResponsive UI tab from help->Visual Studio Performance Manager 

How to avoid this report while install our extensions? How to remove from Ui Unresponsive tab?

Answer 1

The obvious answer is, don't make the UI unresponsive.  ;)

Is your extension performing some long activity, either CPU bound or waiting for I/O or network?  If so, then you need to run that as a background task, so you can free up the UI.

Hi PKarthick,

Welcome to the MSDN forum.

This step is actually VS automatically recognize your plug-in and then automatically categorize. Perhaps, as Tim says, does your plug-in need to load a large number of events, and if so, he will have to conflict with other vs events, resulting in a stuck-in unresponsive situation. There is also the possibility that your plug-in code has a lot of synchronization events instead of using asynchronous operations, resulting in overlapping VS load events and a lot of CPU, I/O blocking.

To solve it, you should optimize your code. For example, use more asynchronous operations to adjust the code. 

>> You can refer to this document:https://docs.microsoft.com/en-us/visualstudio/extensibility/how-to-provide-an-asynchronous-visual-studio-service?view=vs-2019

Or you can use AsyncPackage to load extension.

For the unresponsive UI approach to diagnosis, you can refer to this.

Best Regards,

Perry

Any update on this.

Answer 6

I would hazard a guess that you should probably try and identify what was your extension is doing for that 9 seconds on the main UI thread. That's the key question you need to answer. The following articles might help get you pointed in the right direction:
