Note: However, you cannot install a weak named assembly into the GAC. Before we proceed with the installation of the above 2-3 methods, we must ensure that the project has a strong name.
Adding a name to a project requires the following three steps:
1. After the project has been debugged, use the Sn.exe tool to generate a key. Sn-k "The full path of the generated key".
As in the command line input: Sn-k d:/mykey.snk
2. Associate the key with the project's assembly: Project Properties--sign----------Select the strong name key file for the assembly.
In addition, there is another way to modify the properties of the "AssemblyKeyFile" in the project's AssemblyInfo.cs file.
such as: [Assembly:assemblykeyfile ("D://mykey.snk")]
3. Rebuild the project set.
