Proposed BuildFunc Signature

[Ryan Riley]

Where might I find the proposed BuildFunc signature? I can't seem to find it now.

[Mark Rendle]

Func<AppFunc, AppFunc>

Thought that was MidFunc?

From https://groups.google.com/d/msg/net-http-abstractions/gC9alOlvhhg/7cwe3FMK99IJ

BuildFunc = Action<Func<IDictionary<string,object>, MidFunc>>

Yes, you're right of course. I was having a brain fart.

What is the dictionary in the BuildFunc? Is that the same as IAppBuilder.Properties?

[Mark Rendle]

Yes. It's for application- rather than request-level info, where the Server can put capability info, for example.

Hmmm. I think I’m responsiuble for those names so…

AppFunc we know

MidFunc is Func<AppFunc,AppFunc>

BuildFunc would be, if we want to have feature parity with IAppBuilder.Properties, which I think would be the best option to get the blue badges to drop their IBuilder alltogether and standardize on what we come up with:

static void MyApp(this Func<IDictionary<string,object>, MidFunc> builder) {

return properties => new MyMiddleware(properties).Invoke;

}

Any ideas?

Or

static void MyApp(this Action<Func<IDictionary<string,object>,MidFunc> builder) {

builder(properties=>new MyMiddleware(propertioes).Invoke)

}

this looks not as nice but has teh advantage of making the builder a little bit more like a thing that is tangible for middleware authors.

What do we think?

Any benefit to returning the builder for chaining? (Just thinking out loud)

static Action<Func<IDictionary<string,object>,MidFunc> MyApp(this Action<Func<IDictionary<string,object>,MidFunc> builder) {

      builder(properties=>new MyMiddleware(propertioes).Invoke);

      return builder;

I've been playing around with BuildFunc extensions in Owin.Limits (yes, considering a rename), to see what the experience would be. This is what one would see, intellisense wise:

Can't say I 'like' it. 

By all means, please review the code. :)
