ComAssembly Data Type (ASSL)
COM assemblies might pose a security risk. Due to this risk and other considerations, COM assemblies have been deprecated in SQL Server 2008 Analysis Services (SSAS). COM assemblies might not be supported in future releases.
The ComAssembly element contains a reference (either the fully qualified file name or the programmatic identifier) to a COM library associated with an instance of Microsoft SQL Server Analysis Services or with a specific database on an instance of SSAS.
The corresponding element in the Analysis Management Objects (AMO) object model is ComAssembly.
