Cannot load assemblies ( windows 7 visual studio 2010 )

I loaded some old assemblies in my project yesterday and now when i cannot load them, they appear with a yellow mark on them in the references. I have no idea what the hell i开发者_Python百科 am doing wrong. I really need some help.

when they appear with the yellow mark it means they cannot be found, look at their properties and check that they exist in the place they should. if they dont then re-reference them from another place they exist

If you open the Property Toolwindow and click (select) the assmeblies in referneces that show up with a yellow mark, you will see an entry in the property toolwindow for Path. This is the path that Visual Studio is using to locate the assembly. If the assembly doesn't exist there - you'll get this kind of error.

To fix the problem, either:

1. place a copy of the assembly at the location where VS is searching ... or
2. remove ad re-add the reference from the correct location.
