The expression "a"="a" returns False. What the heck is going on?
Edit: Sorry, I'm working in VB.NET, not C#
Update: When I copy the expression into Notepad++, it shows "?a"="a". Can it have something to do with encoding?
<strike>That expression is not legal C#.
You aren't getting an error because the FuncEval (the ability to execute code in the watch or immediate windows) uses a different parser with various issues.
These issues may eventually be fixed by replacing this parser with Roslyn.</strike>
EDIT
<strike>I suspect that the VB.Net parser used by FuncEval doesn't intern strings.
If you run this expression outside of FuncEval (eg, LINQPad), it returns true.</strike>
Second EDIT
You have an unprintable character in the first string.
Notepad++ shows it as a ? because your text file is using an encoding that doesn't support the character.
