There should be other posts online from ESRI on how to setup the SDK to work with VS2010.
I personally just use VS2008 and all of the objects and controls are there.
There is a procedure to get the controls to appear in VS2010, if you find it and you get it to work, please post the solution.
I may do this myself, but my goal is in 2014, not this year.
Cheers.
