Editing .sln file - WebsiteProperties

Hi,

So I have created my website in Expression Blend. Lately, whenever I press ctrl-shift-b it gives me an error:

Although when I open it in Microsoft Visual Studio 2010 it works fine. Here is what my sln file looks like:

Is because I’m using visual studio 2010 and expression blend 3 is compatible? How do I fix that?
