About DLL

First of all, when we are sure about that now the time has come to release this DLL to others where they can only use it not able to see the code behind the functions which they use in their pages. For that we need to build the class library project in release mode , on successful build you get a release folder in both Bin and Object folder of your class library project but you need to take the DLL file of Bin folder but you need to take care to that it also makes a .PDB file. A program database (PDB) file holds debugging and project state information that allows incremental linking of a Debug configuration of your program. A PDB file is created when you build your class library project.

So you need to take the DLL file in a separate  folder and whenever you require to use that DLL you simply need to reference that DLL from that separate folder but you can still found that while debugging with F11 you see the code of your DLL file and its because your DLL maintains a link your class library project but it only happen when you referencing that DLL at your local machine where you build your class library project and if you use it at any other machine then DLL won't able to link to code and during Debugging it simply pass through the function without going into the code of that function.......

you must have build your DLL in debug mode in VS. Please build it in Release mode and then copy the same DLL from release folder under bin.

Also when you are referencing the DLL in another project, please check that you havent' added the project reference of class library.
