Custom WebApi controller not triggered

I'm going blind, and a bit crazy over what should have been a quite easy task.
Trying to add a custom WebApi to my Dynamicweb 9.13.4 solution, but it just wont work..

This is what I got. The source code is attached.

WebApiEnabler.cs

Controllers/GeneralController.cs

This just show a 404 if I try to open the page.

Also, no message is being logged through the LogManager.
However, if I comment out everything in GeneralController.cs I do get log messages in the event viewer.

Looks like the notification subscriber is not been hit whenever I use my controller code.

What am I missing?!

Try to use

var request = authenticateArgs.Application.Context.Request;

Instead of httpcontext.current. This is so early in the request that current.request is not set.

Then I get:

'IApplication' does not contain a definition for 'Context' and no accessible extension method 'Context' accepting a first argument of type 'IApplication' could be found

Ah - it is private!

Try with Dynamicweb.Context.Current.Request

And check that request.path has a value!

Still the same result. It really does not look like the WebApiEnabler is the problem.
Whenever I comment out all the code in GeneralController.cs:

I do get this in my event viewer:

Mening that this code, has been triggered:

When I uncomment the code in GeneralController.cs I do not get any events in my event viewer...

Your browser shows localhost:9001 yet your logs image shows a DW machine called DW-D026. Are you sure you are testing the correct thing?

Yes, I get the same result in localhost. I just tested it quickly on another solution earlier today. But that has nothing to do with the real issue here.
I get the same result on both localhost and hosted solutions.

But does it look like my code (full project attached in main post) is correct?
Do any of you make it work on your local solutions?

Hi Martin,

Have you checked if your notification subscriber 'WebAPiEnabler.cs' is present in the list of notification subscribers? If it isn't, that may be why the notification subscriber does not get hit

I'm currently trying to see if I can figure out why it is not working, by using your code from the attachment. I'll return with more info as soon as I've had a look at it

/N.W.P.

I got it to work on my local solution with the following code:

What I noticed from my testing was, that whether the notification subscriber shows up in the list of notification subscribers or not seems to be connected to: the type of project, the version and which packages are used in the solution (assuming the code looks ok). I'm not 100% sure yet what exactly causes the notificaiton subscriber not to be shown when a controller is present (without debugging the source code) but I got it to work by creating a new Class library (.NET Framework - version 4.7.2) and adding packages to my newly created solution from a working custom webapi's packages.config file. I've attached my working project in case you want to have a look at it

Thanks Nicholai!

I can confirm that it is working here too. But it does not look like the code is the issue.
Tried to copy the same code as you had into my project, but it did not work.

When I added your prosject into my solution it worked as expected. Think there is something with how the project was created in Visual Studio.
I was missing a few files and folders which you had in your project.

Anyway, it is working. Thanks for your time helping me out :)

You're welcome :)

Yes, the issue here seems to be related to the project-setup and the packages used in the solution
