Why is Assembly.GetCustomAttributes suddenly throwing TypeLoadException on build machine with Silver
- by andrej351
A short while back i had to display the current version of our Silverlight app. After some googling the following code gave me the desired result:
var fileVersionAttributes = typeof(MyClass).Assembly.
GetCustomAttributes(typeof(AssemblyFileVersionAttribute), false) as AssemblyFileVersionAttribute[];
var version = fileVersionAttributes[0].Version;
This worked a treat in our .NET 3.5 Silverlight 3 environment. However, we recently upgraded to .NET 4 and Silverlight 4. We just finished getting our build machine working and found that the unit test for this code was throwing the following exception:
Exception Message:
System.TypeLoadException: Error 0x80131522. Debugging resource strings are unavailable. See http://go.microsoft.com/fwlink/?linkid=106663&Version=3.0.50106.0&File=mscorrc.dll&Key=0x80131522

I have never seen this exception before and the link in it points nowhere. It is only throwing on the build machine and not on my development box, so i'm going through a process of trial and error to see any differences between the two.
Any idea why this might be happening??
