Code fix for adding null-check in a nullable context

[marinasundstrom]

Something I miss in a context where variables are nullable is a fix to either add an if-statement or a .? (if applicable) when null could be expected.

It would minimize the number of key strokes.

The exact behavior should be discussed. But preferably, it should be a suggestion.

I have identified 2 different fixes:

1. Put an if (x != null) statement at a particular occurrence.
2. Surround the rest of the code block. Find the place in the current scope where the nullable variable is first dereferenced. Put an if (x != null) statement around the remainder of the code in that scope.

The type:

public class Foo 
{
    public Bar? Bar { get; set;  }
}

Before fix:

var bar = foo.Bar;

if (bar.X == 0) 
{
    Console.WriteLine(bar);
}

After fix:

var bar = foo.Bar;

if (bar != null) 
{
    if (bar.X == 0) 
    {
        Console.WriteLine(bar);
    }
}
