I've just encountered similar issues when upgrading VisualBasic forms, going from VisualStudio 2010 to VisualStudio 2013. There appear to be two ways to add existing items.

Problem: If I choose Main Window->Project->Add Existing Item and pull in only the file formname.vb, the result appears to be interpreted as code only (no designer), points to the original file (rather than taking a copy to the new project) and has other issues.

Solution: If instead, I go to the Solution Explorer window, click to select the project (as opposed to the lower level objects in the tree) and then right click in the window, the resulting menu offers Add->Existing Item. Using this version works as expected, requiring only that I locate the formname.vb file. No manually copying files, no pointing to mulitple files, no editing scripts, etc. I'd guess the same applies for forms written in C.
