LKBEN10808: Howto create an assembly key file with a strong name in .NET programming


Symptom

The strong name is used for uniqueness of the assembly and for security. It also makes shure that the right assembly gets loaded.

Cause

This is by design

Solution

Assemblies use a cryptographic signature (also call a strong name) to share an assembly among applications on the local machine.

Use the sn.exe tool to create a key file:
sn -k StrongNameFile.snk

If your path environment variables aren't set, you'll have to go to the C:\Program Files\Microsoft.NET\FrameworkSDK\Bin\ directory to run sn.exe)
The filename "StrongNameFile.snk" can be any name you want.

To use the key you can use the following in c# programming:
        
...
using System;
using System.Reflection;

[assembly:AssemblyKeyFileAttribute("StrongNameFile.snk")]
...

For more information have a look at the microsoft SDK. (= software development kit)
