Documentation for the csharp-functions Generator

METADATA

Property	Value	Notes
generator name	csharp-functions	pass this to the generate command after -g
generator stability	STABLE
generator type	SERVER
generator language	C#
generator default templating engine	mustache
helpTxt	Creates Azure function templates on top of the models/converters created by the C# codegens. This function is contained in a partial class. Default Get/Create/Patch/Post etc. methods are created with an underscore prefix. The assumption is that when the function is implemented, the partial class will be completed with another partial class. The implementing code should be located in a method of the same name, only without the underscore prefix. If no such method is found then the function will throw a Not Implemented exception. This setup allows the endpoints to be specified in the schema at build time, and separated from the implementing function.
