Question

We use a software from another company for one of our products. A developer from that company is kinda 'old' and works in C (no offence). We work in .Net 3.5 (C#).

He asked me if it is possible, with the same source code (presumably in C, maybe C++), to create an assembly that he could compile both a managed and unmanaged version.

Are there any good reason to do this?

Was it helpful?

Solution

In order to compile to managed assembly the code needs to be written using Managed C++ Extensions. Please note that C is not an OO language so you cannot compile to a managed assembly.

The primary reason for doing this is if you have an existing code base written in C++ that you want to use directly in .NET application without resorting to P/Invoke.
