Hello folks,

no need to go with .NET Framework 3.5 since 'System.Console.Clear' is present
starting with .NET Framework 2.0.

A 32-bit WINEPREFIX with .NET 2.0 will do too for reproducing.

Starting the .NET console app directly from terminal creates a bare console.
Since your app relies on extended CUI functionality (screen buffer) it needs to
be run with with 'wineconsole' which provides this.

Use 'start.exe' helper which automatically does this for you
('CREATE_NEW_CONSOLE' ensures this because app is of
'IMAGE_SUBSYSTEM_WINDOWS_CUI' type).

$ wine start ConsoleClear.exe

IMHO no bug here. In case you have a GUI project (WinForms project) and want to
do console debug/output, allocate a console with AllocConsole().

Regards
