Hi,

I need to access a couple of external assemblies for a SQLCLR assembly. AFAICS one way to do this is to:
(a) Set the permission level to 'External' in the .NET project.
(b) Grant the dbo of the relevant database 'External Access Assembly' permissions
(c) Mark the relevant database as 'Trustworthy'

I've done all three but still get a permissions error when the CLR tries to access the System.Runtime.Serialization.dll module.

Can anyone suggest what else might be required?
Regards,
Viv
