Commented Issue: Don't suppress internal-only rules in source [649]

Comments: Line 234 of the C# version(D:\git\aspnetwebstack\src\WebApiHelpPage\Areas\HelpPage\SampleGeneration\HelpPageSampleGenerator.cs): [SuppressMessage("Microsoft.Web.FxCop", "MW1201:DoNotCallProblematicMethodsOnTask", Justification = "The sample generation is done synchronously.")] The same also occurs in the VB version.
