By the way, not sure where the VB.Net comes into play. You don't mention that at all.

Solution 1

Your question is not very clear, but I suspect you are trying to debug with a non-debug version of the DLL. Try rebuilding it with DEBUG enabled.

I have done.Assembly is not loaded during debuging.

Sorry but this does not really help, I am still not sure what is happening or what your program is trying to do.

I think what he's trying to say is his breakpoint is telling him that it's not reachable when he tries to run the debugger (the breakpoint symbol goes from solid to just a circle with an exclamation symbol).

Assembly is loaded only when needed.

Solution 2

You usually get this warning when the executable you've marked as your main entry point does not load the dll at all or alternatively, when you made changes to the DLL code and didn't recompile.

There could also be an error causing your executable not to load the dll, in which case, you'd get the same effect of not loading the dll at all.

By the way DLL can be delay-loaded in some situations so you won't really know if you breakpoint is valid until the DLL is actually loaded.

Uhm.. yeah... Of course

what is the solution?

Check to see if your application is actually loading your dll. I've had a similar issue before where I thought there was something wrong with my dll only to notice the application was loading another version of the same dll in a different directory.
