Assembly Data Type (ASSL)
COM assemblies might pose a security risk. Due to this risk and other considerations, COM assemblies were deprecated in SQL Server 2008 Analysis Services (SSAS). COM assemblies might not be supported in future releases.
The Assembly data type serves as the base data type for the ComAssembly element, which represents COM libraries associated with the instance or database, and the ClrAssembly element, which represents .NET Framework assemblies associated with the instance or database. For more information about assemblies, see Multidimensional Model Assemblies Management.
The corresponding element in the Analysis Management Objects (AMO) object model is Assembly.
