Sorry to bother anyone with this question, but I\'ve been researching this for hours, with no resolution yet:
I am porting a rather massive application to the 10.0 C
In my case what helped was changing the TargetFramework in the .VCXPROJ to :
v4.0
But as you've mentioned you need to compile against 3.5 I am not sure what you can do in that case.
