Obviously, the new 24.2.0 has a bug in the compiled library (ToolkitPro2420vc170U.lib). The linker crashes with 

unresolved external symbol "__declspec(dllimport) public: __thiscall CXTPWinApp::CXTPWinApp(void)" (__imp_??0CXTPWinApp@@QAE@XZ) referenced in function "public: __thiscall CMyApp::CMyApp(void)" (??0CMyApp@@QAE@XZ)

Please help!

Are you using _XTP_USE_WINAPPEX macro? If yes, please make sure you have it defined for both Toolkit Pro project and your application project. Once defined for the Toolkit Pro project the libraries have to be re-compiled.

That sounds difficult: I compiled the ToolkitPro with the Deployment Routine that Codejock provided and changed nothing between 24.1 and 24.2! Probably, there is another problem. By the way, it crashes with the unicode setting, but not with the multi-byte character setup ...

The only thing that could have caused that linking error is using  _XTP_USE_WINAPPEX in one project when it's not used in another. For example, your project can have it defined in the compiler settings for the selected configuration, but ToolkitPro was built without  _XTP_USE_WINAPPEX defined for the same configuration, or vice versa. You need to carefully review settings of both projects and make use of that macro consistent or remove it completely. Don't forget to rebuild the affected projects in order the changes to take effect.
