CS error generating Project files

Just added my first C++ files to my project, and when i try and generate project files, so I can see the C++ files in the content browser, I get this error.

While compiling G:\Projects\bball\STR_StrongStyle_v2\Intermediate\Build\BuildRules\STR_StrongStyle_v2ModuleRules.dll:
g:\Projects\bball\STR_StrongStyle_v2\Intermediate\Source\STR_StrongStyle_v2.Build.cs(3,14) : error CS0101: The namespace '<global namespace>' already contains a definition for 'STR_StrongStyle_v2'
g:\Projects\bball\STR_StrongStyle_v2\Intermediate\Source\STR_StrongStyle_v2.Target.cs(3,14) : error CS0101: The namespace '<global namespace>' already contains a definition for 'STR_StrongStyle_v2Target'
ERROR: UnrealBuildTool Exception: Unable to compile source files.

Not sure what this means. I googled around for similar issues, but i’ve only seen this happen with plugins. Any ideas?

Deleted Intermediate and Saved folders. Fixed it.
