How about copying/pasting code, inserting tabs into code, inserting break points into code, how many projects you have, references, when you save, why your code wont compile.

Visual Studio is probably the primary reason I'm even bothering with Microsoft but fuck me they collect a lot of unnecessary shit. They claim its "anonymous"... Some of this doesn't seem so anonymous to me:

"Context.Default.VS.Core.User.Location.GeoId":x, "Context.Default.VS.Core.BuildNumber":x, "Context.Solution.LastSolutionBuildID":x, "Context.DebugSession.VS.Diagnostics.Debugger.DebugSession.StartupProject.UniqueGuid":"{x}", "Context.DebugSession.VS.Diagnostics.Debugger.DebugSession.UniqueGuid":"{x}", "Context.Default.VS.Core.User.IsInternal":"False", "Context.Default.VS.Core.User.IsOptedIn":"True", "Context.Default.VS.Core.User.IsMicrosoftInternal":"False", "Context.Default.VS.Core.User.Type":"External", "Context.Default.VS.Core.User.Id":"x", "Context.Default.VS.Core.Machine.Id":"x", "Context.Solution.ActiveProjectGuid":"{x}", "Context.Solution.SolutionSessionID":"{x}", "Context.Solution.SolutionID":"{x}"

Short of actual source they send everything (and details) you do in VS in real time.
