We already suggest a code fix for string.Format (on CC0048) to use string interpolation. Let's suggest one for Console.WriteLine.

Should work with:

• WriteLine(String, Object)
• WriteLine(String, Object[])
• WriteLine(String, Object, Object)
• WriteLine(String, Object, Object, Object)
• WriteLine(String, Object, Object, Object, Object)

This:

Console.WriteLine("some {0} text", adjective);

Becomes:

Console.WriteLine($"some {adjective} text");

Category: Style
Severity: Info
Diagnostic id: CC0095
