How do I create a standard DLL library (not an assembly housed in a DLL) in C#, so that it can be used by unmanaged applications?

That is not possible, C# code will always been managed code however you can call methods from unmanaged code. Take a look at these articles:

Thanks! So one can access managed components from unmanaged applications...

Then I may need to create a dll based on the "class library" C#/vs.net project type.

But then, how do I call its functions from an unmanaged app?

You will have to write your C# class library as a COM object as is shown in the links jonorossi wrote above. Then from your unmanaged application you can access your C# project as any other COM object.

The problem is I don'y have access to the source code of the unmanaged app. It's just prewired so that it accepts dll shared libraries, not COM objects. What can I do?

Well the only way I can think of is to write your C# class library as a COM object and then create a native DLL (not in C#) which the unmanaged app can load, and make your native dll call your C# COM object.

So you would have the unmanaged app, your managed C# COM object, and an unmanaged dll interfacing between them.
