Debugger should use larger string truncation limit when evaluating from the Debug Console

[gregg-miskelly]

Steps to reproduce

1. Create a new C# Console app
2. Replace the content with below
3. Set a breakpoint where indicated
4. Start debugging
5. From the Debug Console, evaluate 'longString'

Expected behavior

The full value of longString should be displayed (up until a fairly large truncation value)

Actual behavior

longString is truncated after 1024 characters

Work around

Right click on the value in the Debug Console and invoke 'Copy'

Content of the app

    public static void Main()
    {
        string longString = "[" + new string('*', 1024) + "]";
        Console.WriteLine(longString); // breakpoint here
    }
