I have been customizing my DotNetNuke source code for my company and keep getting stuck at the same problem. When Reflection tries to create my SqlDataProvider class, I get Cannot Create an Abstract Class when I'm debugging. I haven't been able to get SqlDataProvider working with any of my modules. Right now I'm debugging a third-party module and I can clearly see reflection is calling CreateObject(CTV.CRM.SqlDataProvider, CTV.CRM.SqlDataProvider). This is the exact namespace & assembly name of what needs to be created. After Reflection calls CreateObject I get "MissingMethodException was unhandled by user code." I can't tell if that means the SqlDataProvider library was not found, or if there is a problem with a class in the provider. I've recompiled everything without errors and all my dlls are in the website\bin folder. Does anyone know what I could be doing wrong? 

Hi,

If I use the module template provided by the DotNetNuke team:

• controller, dataprovider, and info objects (<file>.vb) should be placed in the webdsite\App_code folder
• other files should be placed in the website\DesktopModules\<modulename>.
• No project are required
• The reflection is done as you mentionned (without the assembly name parameter)

And all things should be ok
