I was trying to run the WilsonORMapperExample2005 using firebird embedded version and having problems.

When I run the winform app it just hangs for few minutes and then throws this error.
"The CLR has been unable to transition from COM context 0x1a3008 to COM context 0x1a3178 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations."

So when I debug the Firebird ADO.NET source, it is throwing an exception in the FbCommand.Prepare method. The exception that I see is
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
The same ADO.NET provider works fine when I create a simple .net app without using ORMapper.
Anyone faced this issue before ?
2/10/2006 6:24:42 AM The current version (v4.2.1) has broken some 3rd party database usage, so check out the next version (v4.2.1.1) when it comes out -- later today hopefully. If that doesn't work then let me know and I'll reinstall Firebird and test it -- I know it used to work, but I haven't tested it myself in the last release.

Thanks, Paul Wilson
