This knowledge base article describes how to connect to the SpiraTest, SpiraPlan & SpiraTeam SOAP web services using .NET code written in C#. The code assumes that you're using Visual Studio 2008 or later and are using the newer .NET 3.0+ Windows Communication Foundation (WCF) "Add Service Reference" rather than the older .NET 2.0 ASMX web service client.
A customer asked us for some sample code that illustrated how you can retrieve a filtered list of test sets using the Spira API. This example includes sample code using the Spira v5.0 API.
