Running xLim under Mono 1.2.6

There’s a small update to the last post on xLim portability. The situation is a bit better than it seemed to be.

XPO + Mono (SUSE SLED)

XPO runs under Mono. It can’t work with the the Microsoft SQL Provider since the MS SQL support under Mono is far from perfect for obvious reasons. MySQL provider does work but, as developers have found out, you’d need to change

string[] strArray = (string[])new ArrayList(dictionary.Keys).
  ToArray(typeof(string));

to

string[] strArray = new string[dictionary.Keys.Count];
dictionary.Keys.CopyTo(strArray, 0);

in the XPO sources in order for the distributed caching to work. That’s because dictionaries in Mono do not have full support yet.

Autofac + Mono (SUSE SLED)

There are 6 unit test failures:

BugFixture.IncorrectExceptionThrown1
Builder.ConcreteRegistrarFixture.RegisterThreeServices
Builder.ConcreteRegistrarFixture.
  RegisterTypeAsSupportedAndUnsupportedService
Component.Registration.ContextAwareDelegateRegistrationFixture.
  CreateFromStrongFactory
ContainerFixture.IntegrationTest
DisposerFixture.ReferenceNotHeld

Additionally there is an issue while using binary remoting across the platforms (from SLED+Mono to .NET Windows and vice versa). DateTime cannot get through, for some reason.

Theoretically, Autofac, XPO and the design with the portability in mind is all you need in order to create xLim server and engine functionality that works on Mono. So we’re in good shape here for the xLim 3 server prototypes by summer.

Web UI has got some chance of being implemented quite soon in a performant manner as well (Silverlight grid, as stated in “DevExperience Roadmap 2008″, could be delivered on summer). Additionally there is some chance that existing ASP.NET controls would work under Mono as well.

The picture for the xLim Desktop UI under Mono so far is still the same - there are no DevExpress controls any time soon, unless Silverlight grid would be capable of running on desktop. But that’s just a tiny fraction of the required UI bits.
