Removal of System.Composition.Web.Mvc and the support for .NET 4.0

Aug 23, 2012 at 9:40 AM


I'm integrating MEF2 into ASP MVC 4 with .NET 4.0.

I'm using System.Composition.Web.Mvc.CodePlex and I am surprised to see that it was remove in revision fa1ea50c2b69 from Jun 29, 2012.

There used to be a directory oob/src/System.Composition.Web.Mvc but it was deleted.


The new registration model of MEF that comes with .NET 4.5 only support .NET 4.5 but I am using shared hosting (DiscountASP) which does not support running ASP.NET 4.5 just yet so I need the support for .NET 4.0

Why did you choose to remove the support for .NET 4.0 ?

Thank you,

I am also looking forward MEF 2.0 to be supported in .NET 4.0.

Hola !


I would like to start to learn and understand MEF and I am also fixed to Net 4.

Looks like bad politics, the solution file is also VS2012 [??].

Completely disappointed ....


Best regards,
