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

Jaish Mathews yes you asked it i read , interfaces always public by default so i think vs should look into it or their templating should add

Jaish Mathews · Answer

Hmmm. That was the 1st Q I asked and you mentioned YES & YES Did you declare your interface with "public" accessibility explicitly?

Jaish Mathews · Answer

can you share IRegistration interface body in IRegistration.cs?

Thanks all who responded to my query , Yes all the reference are added and secondly Jaish Mathews I have added the references Did you declare your interface with "public" accessibility explicitly? 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 ?
