Summary

Due to restrictions on the kinds of assemblies that can be loaded, it is not possible to use the adTempus client from a SQL Server CLR assembly

More Information

The adTempus client depends on Microsoft's WCF framework for communication with the adTempus server. Some of the .NET framework assemblies that WCF depends on are mixed assemblies (containing native code), which SQL Server does not allow to load. Therefore the adTempus client cannot be used from SQL CLR assemblies.
