Azure Stream Analytics—Extensibility with C# custom code UDFs
Updated: 05 November, 2019
Developers creating Stream Analytics modules in the cloud or on Azure IoT Edge can now write or reuse custom C# functions and invoke them right in the query through user-defined functions. This enables scenarios such as complex math calculations, importing custom machine learning models using ML.NET and programming custom data imputation logic. Full-fidelity authoring experience is made available in Visual Studio for these functions.
