如何将Azure函数的入口点放在.NET DLL中？

Question

The Azure Functions samples illustrate how to put the process entry point within a C# script file .csx . However, how can I achieve the behavior with a regular C# library (DLL) instead? Can I get Kudu to compile the library first much like it is done for Webapp?

Answer 1

Joannes,

This is not currently supported, but you can publish your assembly with your function as described here and just have your function entry point call the appropriate method in your assembly:

#r "MyAssembly.dll"

public static void Run(/*...args...*/)
{
    MyAssembly.MyMethod(/*..args...*/);
}

Answer 2

As of the writing of this question, it was not supported, but now it is!

Excerpt from wiki:

{
"scriptFile": "PreCompiledFunctionSample.dll",
"entryPoint": "PreCompiledFunctionSample.MyFunction.Run",
"bindings": [
    {
        "authLevel": "function",
        "name": "req",
        "type": "httpTrigger",
        "direction": "in"
    },
    {
        "name": "$return",
        "type": "http",
        "direction": "out"
    }
],
"disabled": false
}
