Visual Studio crashes when adding a parameter to a function #40451
Description
This issue has been moved from a ticket on Developer Community.
[regression] [worked-in:16.4]
I have a method with two overloads:
Private Function MonthToActualYearMonth(ByVal theMonth As MyEnumType) As Integer
Public Shared Function MonthToActualYearMonth(ByVal theYear As Integer, ByVal theMonth As MyEnumType) As Integer
And a line of code calling the wrong method:
Dim aBla = MonthToActualYearMonth(myMonth)
I get a squigly red line underneath the method call with the following error (which is correct):
Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class.
I want to add the missing parameter to use the shared method instead of the private function. I add my cursor after the first parentheses and start typing to add the missing parameter. When I finally type the "," Visual Studio crashes.
In the Event Viewer in Windows I find the following back:
Application: devenv.exe
