We have a plugin created for our test framework based on http://archive.msdn.microsoft.com/UnitTestExtendSample which uses the vsip namespace, we want to migrate it to 2013 but the solution fails to build with
Error60 The type or namespace name 'Vsip' does not exist in the namespace 'Microsoft.VisualStudio.TestTools' (are you missing an assembly reference?)
I am not able to find this namespace in Vs2012 and 2013.What is the equivalent namespace for this.
