First off, I'd like to say that this is a really nice extension and is something I've been wanting in Visual Studio for a while. The fuzzy searching works just as I'd expect. I need a feature similar to this for my C++ app and I'll probably try and learn from this if I can.

Anyways, I'm getting a crash when using the "Implement pure virtual functions for base" feature in Quick Actions. This is in Visual C++, by the way. I'm not sure why this would affect that, but I tested it was this extension by disabling it to see if the crash still happened.

can i reset shortcut?
for example
alt + M ===> alt+\

I have no idea what's involved in supporting a new Visual Studio version, but boy would it be great to have this extension in VS2019!

Synchronous packages are now deprecated in VS2019. Conversion is not really complicated and should be relatively straight forward.
Just follow the instructions on the following page:

Thanks
