Registering a DLL. When I need to register it in GAC?

Question

As title, In order to register a DLL, when I need to register it in GAC?

I simply took an old dll, decompiled with JetBrain, modified an URL (in Setting.cs) and recompiled.

Now I would substitute the old dll with this one and test if everything is good (so my site will be able to reach the new URL).

I ask you:

• I need to register it or I can just substiute the old dll ith this one?
• If I need to register it, I must register in GAC?

Thanks anyone for your support. Have a nice day.

Answer 1

It depends how the original one was deployed. If this was in the GAC then so should your new one be, etc.
