This is going to be a small post and I am going to share one problem that I faced few days back.
I received a service a web service URL that was written in some different technology other than .NET and I added the the reference of it using add service reference but when I compiled that application,I received many build errors.
Then I just realized that I am using Add service reference option and it uses svcutil.exe to create the proxy. As we know this utility was introduced with WCF and works well for WCF services.
I recalled the way the way we used to write the WCF services like writing different contracts like service contract, message contract and message contract and the way we write in asmx web services is totally different. The assemblies are different as well. So I tried to find where I can get the option to Add Web Reference ( Although I had the option to use the command line utility). I found it here
