I've faced a couple of problems while sharing my Windows 8.1 control via Visual Studio Gallery.
First of I could not upload the VSIX as a control. The website complained: "Your extension type does not match the VSIX type. It should be uploaded as a Tool."
I am unable to find out how to make the VSIX recognizable as a control.
So I've uploaded the VSIX as a Tool. Everything works fine when downloading and installing VSIX through the Visual Studio Gallery website, but it is not findable via the Visual Studio "Extensions and Updates" search.
I suspect these 2 problems are connected. Any insight would be very appreatiated.
