Seems like the 6.1 release of Entity Framework and Devforce 7.2.2 do not get along.  If I change nothing else and use NuGet to upgrade from EF 6.0.2 to EF 6.1, I can no longer build my code-first model project.  I turned on detailed build logging and here is the error:

C:\Projects\WithEF6.1\Fsl*gL\packages\IdeaBlade.DevForce.Aop.7.2.2\tools\IdeaBlade.DevForce.Common.targets(61,5): error : An error occurred during metadata generation and a metadata file could not be created.  Error: Object reference not set to an instance of an object.


Anyone else run into this?

Hi jbiddle61,

As far as I'm aware of, we haven't received any reports on this.

If you could narrow down in your model where this issue is causing, and provide a small sample solution, it'll greatly help us in our debugging.

John, thanks for the sample.

We used reflection heavily when building a CF model and it looks like a particular reflection API has changed within the new EF 6.1. assembly.

Let me discuss this with the lead engineer to find out what we can do to fix this.

I have the same issue (Win Store 8.1 App, DevForce Universal, VS 2013 Prem, EF Code First).

Additionally I can't upgrade 'Microsoft Composition (MEF 2)' via nuget because of ' ...incompatible version of IdeaBlade.DevForce.Core...' (see attachement).


May we expect some DevForce minor fixes soon? Including the latest PostSharp update compatibility, too?

Thanks in advance.

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.

I also have this issue (DF 7.2.2 and EF 6.1).
