Background: I am a novice in C#, and use Visual Studios 2010 Express.
I have a class (let's call it myclass) which I want to use in multiple projects. I used to add classes with Project->Add Existing Item... Which creates a copy of myclass.cs.
Now I just found out that when I build the original myclass.cs it creates a myclass.dll and places it in the release folder of my project.
But when I try to use this DLL, I get the following error:
The type or namespace name 'myclass' could not be found(are you missing a using directive or an assembly refference?
Which is weird to me, because I already have referenced it (it is also in the Reference folder of my Solution Explorer). And I already have added this to my code:
using myclass;
So what am I doing wrong?
Update: When I tried my old method (add existing item -> myclass.cs) the error message goes away. So it's not a matter of spelling things correctly.
