Request handler for a .NET Core function in Cloud Functions

A request handler is a method used to process each .NET Core function call. When creating a function version, you must specify the entry point, i.e., the name of the class containing the handler, e.g., FunctionNamespace.Handler. The handler file name must not contain any . before the extension or at the beginning of the handler directory name, e.g., .handler.cs or .test/handler.cs.

Note

At any given time, a single function instance processes only one request. This allows you to use global variables without the need to ensure data integrity control.

Depending on the programming model, the handler can accept and return different types of data. For more information about this and available ways to set a request handler, see this guide.
