Any ideas how to force a GAC DLL into referenced?

Here is my issue, I constantly use a 3rd party DLL that registers itself into the GAC, and when I use it in my project, it reads it from the gac, and when I deploy, I'm always forgetting to add the DLLs since it is not located in the Bin/Referenced folder.

Anyway to force Visual Studio to add the DLL instead of from GAC?

回答1:

Right click on the assembly reference, select properties, and change "Copy Local" to true. That will cause it to copy the assembly into the deployment directory

回答2:

Copy Local only works if the GAC'd assembly if one reference level deep. For instance, if you have a project that references the GAC'd assembly, and that project if referenced by your web project, then while yes, the GAC'd assembly will be copied to the first project's bin folder, but it won't be copied to your web project's bin folder.

The solution, then, is to directly set a reference in the web project to the GAC'd assembly, and specify Copy Local. Even though the web project doesn't directly use the reference in this case, it will copy it to the web application's bin folder.
