Robert, you are wrong, when you state that uint should be used for SIZE_T.
SIZE_T is an unsigned integer with the size of void* that is UIntPtr.
Paul, you are right, this is a bug in mcs, I reported it:
http://bugzilla.ximian.com/show_bug.cgi?id=76256
If you declare dwNumberOfBytesToMap as IntPtr and cast BUFFERLEN to IntPtr
it will compile on mcs as well, and you will get the same result.

Hi,
According to MSDN, MapViewOfFile should be
LPVOID MapViewOfFile(
HANDLE hFileMappingObject,
DWORD dwDesiredAccess,
DWORD dwFileOffsetHigh,
DWORD dwFileOffsetLow,
SIZE_T dwNumberOfBytesToMap
);
I have some code which looks like this
dataView = MapViewOfFile(dataMap, FILE_MAP_WRITE, 0, 0,
(UIntPtr)BUFFERLEN);
Are you using that declaration?
http://www.pinvoke.net/default.aspx/kernel32.MapViewOfFile
It has a bug. This is the correct DllImport:
[DllImport("kernel32.dll")]
static extern IntPtr MapViewOfFile(
IntPtr hFileMappingObject,
uint dwDesiredAccess,
uint dwFileOffsetHigh,
uint dwFileOffsetLow,
uint dwNumberOfBytesToMap
);
dataView = MapViewOfFile(dataMap, FILE_MAP_WRITE, 0, 0,
(uint) BUFFERLEN);
