Strange error for referencing dll

Hi all,
I have created a .Net control for myself, and put it inside the folder
"framework\v1.1.4322".
Then, I create a new project, reference the dll and draw the control on the
window form.
I am fail running the project and the error is encountered at the line
"InitializeComponent" in the form, claiming that some dependency is missing.

However, once putting the dll outside the folder "framework\v1.1.4322",
everythings go normal.

Do anyone have idea for that?

Thanks in advance!

Don't even try to put it in that folder.

..net assemblies are referenced from two places. #1 the folder in which the
application is stored and #2 the Global Assembly Cache or GAC.

If you're DLL is specialized for your application and unlikely to be useful
to other applications and deploy it into the folder where the executable is
to be stored. If your DLL is likely to be shared by several applications or
requires some strict version management then put it into the GAC. The
assemblies placed into the global assembly cache must be strongly named.

Your control probably falls into the latter category.

Don't even try to put it in that folder.

Why not? The IDE looks for assemblies there, and it can make things a lot
simpler if one does not use strong naming.

You can add a new key under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio \7.1\AssemblyFolders to
point to your own folder for things to appear in the Add references dialog.

If I do want to put it into GAC, how strong should it be named?

Do you have any reference for me?

Thank you very much!

The assemblies in that folder are also duplicated in the GAC. To my
knowledge, none of the .NET assemblies are copied local and all run from the
GAC copy. The references made to assemblies in that or any other folder will
do one of two things. #1 If the assembly is strongly named a copy will be
assumed to be distributed to the GAC of any target machine and the assembly
will not be copied local to the application. #2 If the asssembly isn't
strongly named a local copy of the referenced assembly will be created and
that will be assumed to be distributed along with the application.

There are articles in MSDN pertaining to strong-naming of assemblies.
