Question

I have a Class library project. I am installing this dll produced by the project into the GAC by the command “gacutil /i [Path of the dll]”. This dll is used by a windows application. When windows application runs, it successfully accesses the functions and properties of the dll.
Now I have made some changes to the dll. I have uninstalled the original dll from the GAC and will install the newer dll with the required changes. Now when the windows application uses this dll, the new changes from the dll are not getting reflected in the application. The new changes should reflect into the application as I installed the new dll into the GAC.
The Name, version and Public key token is the same for both dlls. I think it won’t matter as the i have uninstalled the previous dll and installed the new dll into the GAC.

Am I doing something wrong?? Please suggest a solution.

Thanks and Regards,

I would suggest for debugging purposes that you version your dll, then print the version to your application to be sure its being updated. Include the System.Reflection namespace and the code would run look like the following:

Assembly assembly = Assembly.LoadFrom("unknown.dll");
label.Text = assembly.GetName().Version.ToString();
