Using IWeb is very simple. You install the IWeb module and then you start adding you own methods. You will automatically have security for your methods that can be administered from the configuration screen. The only problem is you have to write the methods in VB.
We hoped to allow you to have VB and C# methods in IWebCF (the Windows Communication Foundation based version of IWeb that is also on it's way). So far we haven't figured out a way to do that. So, we decided to make a C# version of IWeb for those who want to write their methods in C#.
The module is called IWebCSharp and can be installed side-by-side with IWeb (also IWebCF can also be installed side-by-side with the other versions of IWeb).
Note: the entry point for IWebCsharp is different then the normal IWeb so you will have to use the client that comes with it not the normal IWeb client connector.
