Hello!

aspnetwebstack is inspiring. Thank you for this project. I appreciate you for moving it to opensource. I'd really like to contribute. I'm a newcomer to opensource development. So, I’m asking for advices from experienced colleagues.

I’ve read carefully “Ways to Contribute”. I’ve chosen Web API issue #150. I've composed a unit test to ensure the bug exists. I believe it is an easy first step in opensource development to solve this issue. Could you tell if this issue worth to be solved?

Alex,

Sounds great! To get set up, I recommend you start by looking at the instructions in this blog [0].

The change is in itself very small – changing the method IsControllerType in the type DefaultHttpControllerTypeResolver [1] to look like this:

internal static bool IsControllerType(Type t)

{

Contract.Assert(t != null);

return

t != null &&

t.IsClass &&

t.IsVisible &&

t.Name.EndsWith(DefaultHttpControllerSelector.ControllerSuffix, StringComparison.OrdinalIgnoreCase) &&

!t.IsAbstract &&

TypeHelper.HttpControllerType.IsAssignableFrom(t);

}

The bigger issue is to write tests that cover it in detail to ensure that there are no corner cases. You can find the unit tests for this class at [2].

Hope this helps!

Henrik

Henrik, hi.

This helped! Thanks for a rapid reply.

Tutorial at [0] is helpful but outdated. Pictures should be updated. “git clone https://<UserName>@git01.codeplex.com/forks/<UserName>/aspnetwebstack” is now “git clone https://git01.codeplex.com/forks/<UserName>/aspnetwebstack”.

Thank you for referencing IsControllerType. I have found it recently by myself. By the way, MVC also has IsControllerType at [1]. The change is very small as I wanted to start with simple task.

I uninstalled MVC4. I have an error and a warning while building aspnetwebstack:

How should I fix them? 

I am developing web-project in a team that based on the recent public version of aspnetwebstack v4. I had to remove MVC4 from my PC to contribute to aspnetwebstack . What the best way you can suggest to stay consistent in both directions?

Regards,

  Alex

I am not sure what the issue is. Could you please try and get the latest source and try compiling from within VS?

Thank you for answering.

Sure. Build results for the latest source is as follows:

 

    Tests: 16, Failures: 1, Skipped: 0, Time: 10,480 seconds

    Tests: 860, Failures: 0, Skipped: 0, Time: 24,818 seconds

 

*** BUILD FAILED ***

 

 

Test failure:

Same result in VS. src build is successful. Same test is failed.

 

I am still searching for the way how to contribute to the latest sources while having MVC4 RC insalled . I found the post [1]. Will it work with the latest sources? I suppose that recent build assemblies and MVC4 RC assemblies have different versions for now. So, it seems like it is now possible to contribute to aspnetwebstack and have MVC4 RC installed. But this should be temporary.

Should this class be valid or invalid ApiController?

 

    public class GenericController<T> : ApiController
