Hi,
This is a question related to a previous question I have asked but I think it required reformulating.
In the past, Express edition didn't use to support extensibility. It seems to be different in 2012 versions though I struggle to find any clear information about this.
I have installed a Visual Web Developer Express 2012 to run some tests and it certainly includes an Extension Manager, and I even have successfully installed extensions (NuGet Package Manager, for instance).
However when I tried to install an extension that I have developed, it would show up in the Extension Manager but the extension menu would not appear under the Tools menu, as it is supposed to (it works on other editions of Visual Studio).
The extension doesn't do anything that shouldn't work on an Express edition. So is it that only extensions developed my Microsoft (or possibly approved by Microsoft) can be installed on Express editions? Or is it that my code is somehow incompatible with the Express editions? (in this case, where could I find documentation about making the coding compatible ?).
Thanks
