assembly not found NEWBIE issue

Just starting out with C# (using VS2008) - am an experienced Java, C++, VC++, VB programmer.

I downloaded an assembly (I guess) from codescales.com; it's a dll.

In my (new) C# project, I added this dll as a Reference -- by browsing to it. I got intellisense working for it, and coded-up a simple example to test it, but everytime I hit the VS "Debug", I get the following Exception. Do I need to "register" or do something to this downloaded DLL to use it properly in my project? (VS seems to copy it to the output dir automatically on build.)

Thanks in advance, AJ

There's a name mismatch, not sure how that happened. Remove the assembly reference. Rename the DLL you downloaded from CodeScales.Http.V0.14.dll to CodeScales.Http.dll. Then add the reference back.

You need to change Framework. Go to 'Properties' and the change '.Net Framework 4 Client profile' to '.Net Framework 4'.
