DLL Mixed Mode

This is a Mixed Mode Assembly, it allows a native payload from Metasploit to be executed from within what is the bare minimum requirements of a valid .NET assembly. The DLL source code is the same as the standard DLL template, the primary difference from a file perspective is that this DLL has the necessary manifest information to be loaded as a managed assembly.

Building

Use the provided build.bat file, and run it from within the Visual Studio developer console. The batch file requires that the %VCINSTALLDIR% environment variable be defined (which it should be by default). The build script will create both the x86 and x64 templates before moving them into the correct folder. The current working directory when the build is run must be the source code directory (dll_mixed_mode).
