[Addin] Multiple ToolWindow

Hello,

It’s my first post in this forum,
I’ve work with VisualStudio and use VB.net programmation.

After several searches, I have not found my solution.

In fact, I want to open my toolwindow previously closed, but that is in the Window menu as shown in the screen below:

This would prevent me to accumulate the same toolwindows.

I remain at your disposal for any additional questions,

Best regards

Armand,
