How targeting .NET 4.0 with Mvvmcross?

I want to use Mvvmcross to make application for several platforms.

I use Profile 104 for PCL library like Mvvmcross, but this profile target .NET 4.5. I want to target .NET 4.0 to use my application on Windows XP.

To do that, I add the xml files

MonoAndroid, Version = v1.6 +. Xml

and

VSMonoTouch, Version = v1.0 +. Xml

in the profile 143 which allows me to target. NET framework 4.0.3.

However, I have a compilation error because it can not find the ICommand interface. This interface is not in the same library between version 4.0 and 4.5, is it why it doesn't work ? Or should I recompile all Mvvmcross libraries with profile 143?

thanks,

This is a Portable Class Library limitation.

See the table on: http://msdn.microsoft.com/en-us/library/gg597391.aspx

Model-View-View Model (MVVM)

Only 4.5

This means that if anyone wants to use MvvmCross on earlier .Net platforms then someone has to build and maintain a non-PCL version.

Since the maintainer of Mvx (me!) has decided to only maintain PCL versions of MvvmCross, then any non-PCL support will have to be created by the community.

For WPF this shouldn't be too large or difficult a job - but it might be...

Alternatively, somebody might be able to do something funky to get the ICommand working... I've retagged this question with portable-class-library to try to lure in some of the MS experts.
