Methods in a .NET 2.0 assemblyExisting native UDFs can still be used

Some V1 design restrictionsNo Excel OM (interface with the sheet – thru UDF call)More restrictive than Excel addins with

Type conversion and supported typesError handling (any exception #VALUE)

Simple load / runtime behavior

UDFs need to be thread-safeUDF security – controlled by server administrator

Registers trusted UDF assemblies with Excel ServicesCan restrict Code Access Security (CAS)
