Question

Who is Noah Richards, and why is his name in the stack track of visual studio crashing? I refer to this specific stack trace.. (on a less important tack, why would this be happening? It is 100% reproducible after adding an opening parenthesis on a protected member of a class in a 50 project solution…

the error in question is:

AlignAssignments.dll!NoahRichards.AlignAssignments.CommandFilter.Exec(ref System.Guid pguidCmdGroup, uint nCmdID, uint nCmdexecopt, System.IntPtr pvaIn, System.IntPtr pvaOut) + 0xb2 bytes

Answer 1

Noah Richards is one of the developers who worked on the 2010 release of Visual Studio. He now works at google but he does have several Visual Studio extensions available on the Visual Studio gallery (and participated in several others).

It looks like you have his “Align Assignments” extension installed and it’s running into an error while processing a key stroke.

He also participates on stack overflow
