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

https://github.com/Azure/azure-webjobs-sdk-script/wiki/Precompiled-functions

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
}

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...*/);
}
