Run C# .NET Framework (x86): try-catch causes SharpLab to become a blank page
Problem
When the undermentioned code snippet is run, you get a blank page (empty <main> tag). Happens with latest Firefox, Chrome and Edge. The try-catch in the code seems to cause this issue, as it only occurs when I add the try-catch clause.
Steps to reproduce
- Open a fresh sharplab.io page
- Set the platform to .NET Framework (x86)
- Set Results to Run
- Paste the following source code:
using System;
X.Ev += () => throw new Exception();
X.Run();
public class X {
public static event Action Ev;
public static void Run() {
try {
Ev?.Invoke();
} catch { }
Console.WriteLine("Hello");
}
}
