# Solution: Visual Studio 2010 beta 2 extension does not load in vs 2010 RC

By Roy Osherove February 23, 2010 In [.NET](https://osherove.com/blog/category/net)

**Historical article** · Originally published February 23, 2010; technical details may be outdated.

like (I think) many others, the extension I am writing for visual studio 2010 beta did not even load on the new visual studio 2010 RC. After searching and asking around, it looks like the main breaking change for me was that I was importing an IServiceProvider type, which in the RC needs to be imported as SvsServiceProvider.

all I needed to do was change form this:

**_\[Import(typeof(IServiceProvider)\]_**

_public IServiceProvider provider;_

To this:

**_\[Import(typeof(SvsServiceProvider)\]_**

_public IServiceProvider provider;_

you can see [some other changes here](http://blogs.msdn.com/noahric/archive/2010/02/11/what-s-new-for-extenders-in-the-visual-studio-2010-rc.aspx).
