COM+ (Component Services) is a runtime and set of services that is an evolution of Microsoft Component Object Model (COM) and Microsoft Transaction Server (MTS).
COM+ (Component Services) is an evolution of Microsoft's original COM standard and the old Microsoft Transaction Server (MTS) product, which first shipped with the NT4 Option Pack. It provides services such as distributed transactions, object pooling, activation, and security.
Although the .NET Framework provides wrappers for COM+ (through the System.EnterpriseServices
namespace), the technology has been superseded by Windows Communication Foundation.
COM+ has been included in the desktop and server SKUs of Windows since version 2000.
