We are still investigating the breaking change caused by upgrading to EF 6.1.
Zbig,
DF 7.2.2 unfortunately has a hard dependency on Microsoft.Composition 1.0.17. I don't know what it would take yet for DF to be compatible with 1.0.20. We'll also be investigating this.
We're also investigating what it would take for DF to be compatible with the latest PostSharp.
We currently don't have a timeline for when the next DevForce release will be.
