Hi all,

I'm trying to build API for my website which uses custom developed module for DNN 6.2 and I experienced an issue that I would like to share with you hoping that some of you would help me.

The Scenario

• I developed custom DNN module (DNN_VBU) that I already use for my website without any issues. (I'm using DNN 6.2)
• The DNN module has some business logic that uses SqlDataProvider class through DataProvider abstract class to access a database.
• Everything works perfect when I create an instance of DataProvider to call some of my methods that access database to load/save data.
• I created complete new Web API 2 Visual Studio Project which has to implement API Layer that will uses the business logic already implemented in DNN_VBU module. So, DNN_VBU has Models (DTOs) and Controllers that I want to reuse in WEB API project (VBUMR_API) which will be a kind of Facade layer that external system will access it to get the business data in JSON or XML format.
• I created simple Controller and WS method which looks like this one:
  
  Very simple, HTTP REQUEST have to call api\albums\1000 and "Get" method executes. VBU is alias to my DNN module (DNN_VBU) and call business logic wrapped in "GetAlbum" method which is another assembly (DNN module).
• The error that I receive is the following:
  
• After debugging I can see that provider configuration member is null.
  
  
• When I'm calling the same method from the assembly which is DNN module itself in which this class is included everything works fine.
  

If someone can help with this issue I would be really grateful. 

Best regards,
