Gets or sets information about the failed assembly.
Assembly: mscorlib (in mscorlib.dll)
This property contains an AssemblyName object that identifies the assembly that caused the security check to fail.
This property is not populated when a security exception occurs in a Deny or PermitOnly stack frame, because the assembly issuing the Deny or PermitOnly security action is not the assembly that failed the stack walk. In these cases, the security exception is created with a constructor that does not require an assembly name, granted set information, or refused set information.
