I got a ton of errors as I re-compiled a Silverlight 4 project in VS 2010 Ultimate. The errors like that "the type or namespace name xxx does not exist in xxx". Actually, all of the needed dlls are in the References. I have struggled but got no solution.
From some forum discussion, I have realized that this type of problem is due to version conflict. Of the several dozens of errors, I could not find the one that is the source one.
Hopefully, someone can help me for this issue.
If it is so hard, should I upgrade to SL5 in VS 2010? Or SL5 in VS2012? Thanks.
