The WSDL tool is a handy tool to generate a proxy class to consume a web service. There is plenty of information out there about it, so I will not go into detail. I will provide some links though. One bit of advice is to add a new Environment Variable to your machine. Here is an example, I named mine Path.
Variable name: Path
Variable value: %PATH%;C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin
You may need to verify that path on your actual machine, it should be the location of wsdl.exe.
Something that is probably over looked from time to time unless you are just always that secure is encrypting your ViewState. While SSL may prevent some things you will may want to make it a bit harder for an end user to see the information stored in ViewState.
Luckily this is very simple. You can set it in the @Page directive (<%@ Page Language=”C#” ViewStateEncryptionMode=”Always” %>) or in the web.config file (<pages viewStateEncryptionMode=”Always” />).
Of course, like many things .NET there are many ways to do this depending on your specific situation. For that amount of detail you should read the ViewState Overview.
If you are making the change to IIS 7 and you use your web.config file to control access there are a couple things you need to know.
This is known as URL Authorization and has changed a little from the older versions of IIS. In the past we could just make sure the site was set to integrated authentication and then set our web.config authentication mode with authroization allow/deny settings and be happy.
I have been learning the hard way there is a bit of a change for those using IIS7 or better. To explain it best I will simply use a couple links to the information I have found.
