Load modified dll at runtime

[Nadcc]

I have developed a c sharp addin on outlook which calls a dll That I have put on a network drive mapped on all machines. the addin will be installed on 1000 machines.

When I get a bug in my application, I go to change the code in the dll and I compile it again and spread it on the mapped network drive. But how to make the client load the new version of the dll at runtime. I need to make all the changes done to the url transparent.

Do you have an idea how can i do this?

Thanks in advance

Once a dll is loaded in an appdomain it cannot be unloaded. You can do something like asp.net does create multiple appdomains and do shadow copying. A appdomain will get a dll from some location and copy it to a temp folder, if the dll changes the appdomain gets recycled and the dll gets copied over again. The application needs to talk to the other appdomain using remoting.

It is kind complicated and I would not really recommend. Maybe you can do some kind of click once or something. Email your users and tell them to restart the app to get the latest changes.
