I have a WCF solution that I use svcUtil to create a client for. The first time I created the client it had two public methods.
I referenced that dll from my VS2015 asp.net 5 web application and intellisense showed both methods, everything worked fine.
I added three more methods to my WCF and regenerated the client.cs. Looking at the client.cs I can see the additional 3 methods.
I removed the reference from my VS2015 asp.net 5 web application and added it back using the browse button and selecting the dll
which had the proper time and date. The additional methods do not show up in intellisense.
