All of the runtime files you need to execute your program must be contained the appx package. If one is missing then you'll get this error. Why VS cannot write a valid manifest for the package, so it can get built properly with all required dependencies, is completely unclear from your question. In chats about it in the Output window when you build the program that would be a start for documenting your question properly. And read up on how you edit the manifest yourself. – Antimonic

Hi, I have added dll in the project and have set the property of DLL to 'Content' in build action and also 'Copy to output directory' to '' 'Copy Allways' but even then i get this error . I have also inspected the "bin\x86\Debug" and "bin\x86\Debug\AppX" both places i find the dll but not working for me. Please help me. @Hans Passant – Role

Is this a c++ project? If not you may need to add -cclib -lstdc++ linker flags in the project settings (Other Linker Flags files) – Flawy
