UI unresponsiveness message shows in our custom extension RRS feed

  • 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?

  • 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.

  • 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:
