Questions tagged [mixed-mode]

A mixed-mode application is any application that combines native code (C++) with managed code (such as Visual Basic, Visual C#, or C++/CLI that runs on the common language runtime).

From MSDN:

A mixed-mode application is any application that combines native code (C++) with managed code (such as Visual Basic, Visual C#, or C++/CLI that runs on the common language runtime).

Mixed assemblies are capable of containing both unmanaged machine instructions and MSIL instructions. This allows them to call and be called by .NET components, while retaining compatibility with components that are entirely unmanaged. Using mixed assemblies, developers can author applications using a mixture of managed and unmanaged functionality.
