Over the last few months, Anthony, one of our PMs on the Visual Studio Ecosystem team has been quietly putting together a central location for Visual Studio extensions. Right now, we're at 351 extensions and counting. Our partners have been adding content the last month and we're all super excited to finally have a single place we can point developers to!
Even Soma (our Senior VP in the Developer Division) has a blog post on it!
Anyways, if you want to make your VS development experience more productive or wished there were certain extensions inside of VS that are missing, check out the Visual Studio Gallery. You might be pleasantly surprised. And ofcourse, if you don't find what you need, go write a Visual Studio Extension and share it with the world! :)
