But, to better guide you to the right information -- do you have a more specific question?
Hello, generally it’s recommended to use web services in remote computing because it’s an open standard, and it’s a basic approach in SOA. Also it’s very easy to create a client of a web service in Visual Studio. Just use “Add Service Reference” for WCF services and “Add Web Reference” for other types of services. The IDE will automatically generate all the code you need to communicate with the service. Please refer to Use WCF Client and Access an XML Web Service in Managed Code.
Now move on to the client technology. If you want to use Windows Forms, you can post your questions on the Windows Forms forum. If you want to use WPF, you can begin with the corresponding topics on MSDN. There’re also a few good books about WPF such as “Windows Presentations Foundation Unleashed” and “Application=Code+Markup”. If you have further questions related to WPF, please feel free to post them here.
