.NET agent v5.20.61.0

New Features

• Async mode: Added System.Web.Script.Services.WebServiceMethodData support to .NET Async mode. All transactions named from this instrumentation will now use the more appropriate naming format of: WebService/{ServiceClassName}/{MethodName}.
• Async mode: Added OpenRasta support to .NET Async mode. This instrumentation now appropriately names transactions using the {Controller}/{Action} format.
• Moved System.Web.UI.Page.PerformPreInit, System.Web.Compilation.AssemblyBuilder.Compile and System.Web.Compilation.BuildManager.CompileWebFile instrumentation configuration elements from the CoreInstrumentation.xml file to the Asp35.Instrumentation.xml file.

Fixes

• Async mode: Resolved an issue where the agent incorrectly handled HttpClient async requests that timed-out or were manually cancelled. These would show up as wrapper errors.
