Answer 1

I have had this problem with VS2015 while building locally in Windows.

In order to solve it, I deleted my build folder (Output Directory as seen in Properties/General) and rebuilt the project.

This always seems to help when strange things happen during the build.

Answer 2

I’ve encountered this error many times in VC++. Do the following steps. They’ve sometimes helped me with this issue:

1. Take a look at the exact location, pointed out by compiler error.
2. Find any external types or classes used there at that location.
3. Change the order of “include path” of those files found in step 2 and rebuild the solution.
4. I hope that help !!!!

Answer 3

I am getting same error with VC2012. Setting up the project properties Optimization to Disabled (/Od) resolved the issue.

Answer 4

In my solution, i've removed output dll file of the project, and I've made project rebuild.
