Can I compose a WCF callback contract out of multiple interfaces?
- by mafutrct
Followup question to http://stackoverflow.com/questions/2502930/how-can-i-compose-a-wcf-contract-out-of-multiple-interfaces.
I tried to merge multiple callback interfaces in a single interface. This yields an InvalidOperationException claiming that the final interface contains no operations. Technically, this is true, however, the inherited interfaces do contain operations.
How can I fix this? Or is this a limitation of WCF?
Edit:
interface A { [OperationContract]void X(); }
interface B { [OperationContract]void Y(); }
interface C: A, B {} // this is the public callback contract
