namespace error

Hmmm. That was the 1st Q I asked and you mentioned YES & YES

It was a blunder as i assume that interfaces are by default public as they are not providing any implementation and visual studio would consider them as public by default , but that was not teh case in my case i need to write the public identifier in front of interface and concrete class and now all works fine :) 

thanks again  

1. Did you declare your interface with "public" accessibility explicitly?
2. Did RegistrationConcrete class implemented the interface "IRegistration"?

YES & YES , on hover over the namespace it says un-necessary namespace as its color shows that it did not get added as viual studio shows the added reference in birght white color . 

 

Solution : I just delete my both class library one for Concrete DB operation and one for interfaces as i just started the project and then re-create and add the referneces and now it works fine i do not know what was the cause ?  

Hi Mark

 

Have you added reference of your interface project  in your CMS_Montioring_Student project and check if your interface is public

 

If not please add and check if issue resolve. 

We really want to know what these highlighted warnings in code is telling about on mouse over? Can you please share?

 

Meantime please check below common scenarios to address related to Interface.
