Compile errors on upgrading to 4.10

Hi friends

I’ve recently attempted to upgrade my 4.9.2 project to a 4.10 engine version and found myself stuck at a compile error.

I’ve never had this problem before and what is weirdest is that I have almost no C++ code in my project.
The only code class I’ve added is an extension of the AInfo class, I made a blueprintable version.

But it does not implement any data types or functions proper, still I get this build error:

And here is the output log for detailed info:

Any help would be incredibly appreciatted <3

Have you upgraded to Visual Studio 2015? I think it may be required for 4.10

Did indeed upgrade to 2015 to no avail, still have the same errors =/
