Descrizione
Version Used
VS 2022 Version 17.11.5 Roslyn 4.11.0 (5649376e0e5f)
Project info C# 12.0 .NET 8.0
Steps to Reproduce
Use the following code:
public static int Add(int a, int b)
{
{
return a + b;
}
throw new InvalidOperationException();
{
throw new InvalidOperationException();
}
{
const int x = 523;
throw new InvalidOperationException();
}
{
throw new InvalidOperationException();
}
}
Expected Behavior
In VS, the unreachable code will dim out showing that the dimmed out region is unreachable. In the above example, we expect all the code from the throw statement onwards to be dimmed out.
Actual Behavior
The resulting dimming is very different and limited to the scope that starts with non-throw statements.
