I was running a .NET app, and all it did was say:
Request for the permission of type System.Security.Permissions.FileIOPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.
After I hit Ok, the app crashed with an exception. I didn’t write it. Others could run it, I couldn’t. What was I doing wrong?
I was running the exe from a network share. Copying the exe to local fixed the problem.
