The attached code seems to work identically for me between mono and .net.

Mono version 2.10.9 Build 0

Microsoft (R) Visual C# Compiler version 4.0.30319.17929
for Microsoft (R) .NET Framework 4.5

64-bit Windows 7 (SP1)

I confirm the bug, running on Windows 8.1 64-bit

Console.ReadKey just hangs on mono, while it works on .NET

I mades some tries using the code on mono github repo, apparently the record returned by

[DllImport ("kernel32.dll", EntryPoint="ReadConsoleInput", SetLastError=true, CharSet=CharSet.Unicode)]
extern static bool ReadConsoleInput (IntPtr handle, out InputRecord record, int length, out int nread);

always have EventType property 0 valued on mono, while it is 1 on .NET
