This issue has been moved from a ticket on Developer Community.

When typing the following start of a line of C# code, VS crashes reproducibly (bold is what I type, italic has been added by auto closing of braces):

foreach ((var i, i))

As soon as I enter the second 'i', VS stopps responding and crashes a few seconds after. I tried this at multiple locations in the code. The result remained the same.
