Unified Communications Managed API 6.0 Runtime

UCMA provides a flexible managed-code platform for unified communication and collaboration that allows developers to implement communication- and collaboration-enabled middle tier services which take advantage of the fact that you have made investment in Skype for Business Server. It allows you to enable same/similar or better UC scenarios as we could do.

An administrator who is preparing to install a third-party UCMA-enabled application on a deployment computer must download and install UcmaRuntimeSetup.exe. Installing UCMA 6.0 Runtime provides all of the UCMA-related functionality needed by a UCMA-enabled application.

Supported Operating Systems

When a customer application is uninstalled, the application uninstall procedure must not automatically uninstall any of the required components (such as .NET Framework 4.5, Visual C++ 14 Redistributable Package, or UCMA 6.0 Runtime), because other applications might require them.
