Description Adam McKenney 2013-06-25 03:05:21 UTC
When creating a simple console application on my Debian Wheezy (stable) and Debian Jessie (testing) you run into an error.

In Visual Studios, when you do "Imports System.Console" you can type Title = "Foobar" without a problem. Even Mono Develop doesn't mark this as an error until you try to compile. Using vbnc, even when you import System.Console, you will get this message:

<long path>/t.vb (5,10) : Error VBNC99997: You've encountered something in the compiler which is not implemented. Please file a bug (see instructions here: http://mono-project.com/Bugs)
<long path>/t.vb (5,10) : Error VBNC30451: Could not resolve the name 'Title'
There were 2 errors and 0 warnings.
Compilation took 00:00:01.5417320

To fix it you have to add Console.Title which is a pain if you have around 20 lines that require it.
This bug works for other things in System.Console like ForegroundColor and BackgroundColor.

If you do not import System.Console, then you get this simple error:

<long path>/t.vb (5,10) : Error VBNC30451: Could not resolve the name 'Title'
There were 1 errors and 0 warnings.
Compilation took 00:00:01.5512160

Test Application's Code:

Imports System.Console
Class Test

        Shared Sub Main
                Title = "Test"
                Console.ForegroundColor = ConsoleColor.Cyan
                Console.Write("==> ")
                Dim inpt As String = Console.ReadLine()
        End Sub
End Class
