Screenshot, source code and 64-bit DLL for testing
Description of problem: When trying to P/Invoke a 64-bit native DLL file on a
32-bit Windows system, Mono's behavior is different from Microsoft .NET's.
Steps to reproduce the problem: Download the ZIP in the attachment. Compile the
CS file using "mcs PInvokeBug.cs". Run the generated EXE file on a 32-bit
Windows system.
Actual results: Mono shows 8 message boxes (all the same; see German language
screenshot MessageBox.png in the ZIP), and finally throws a
DllNotFoundException.
Expected results: No message boxes should be shown; a
System.BadImageFormatException should be thrown (instead of
DllNotFoundException).
How often does this happen? Always.
Additional information: The KeePassLibC64.dll file in the ZIP is from the
KeePass Password Safe project (the call to DeleteManager with IntPtr.Zero won't
do anything). Feel free to use any other 64-bit native DLL file for testing, if
you don't trust this one.
