Sorry for the simple question, but this has been killing me and I can't seem to find the answer. I'm writing a Silverlight 5.0 application in C# with VS2010. .NET 4.5.40805 SP1Rel. In the directives of the codebehind, I've added "using System.Diagnostics;" so I can use "Process()". While intellisense will complete "System.Diagnostics" for me, I can't seem to use the Process class located therein. If I try to "Add reference" via the solution explorer, System.Diagnostics is not there.
Am I using the wrong directive? (http://msdn.microsoft.com/en-us/library/system.diagnostics.process.aspx as well as the object explorer suggests I'm not) Is there somethings I'm missing for effectively adding these references? Please help me with this recurring problem. Thank you.
