Productivity tools and Entity Framework conflict

Question

With Productivity Tools 10.0.10819.19 9 enabled in my Extension Manager, VS2010 Ultimate, I get an error, “The project’s target framework does not contain Entity Framework runtime assemblies” and cannot add a ADO.NET Entity data Model to my SL4 Business Application. As soon as the Productivity Tools is disabled, all works normally. Who needs to know about this??

Hi Gray,

Please review the target framework information in the project's property page. Right click your project and select property page then try to set target framwork 3.5 or 4.0 on your project.

It is 4.0! I reinstalled both the 4.0 framework andVS2010 Ultimate to no avail. Only disabling the Productivity Power Tools would correct the problem.

Answer 3

I had the same issue. To fix, I changed my framework to 3.5, saved and/or built. Then changed back to 4.0 and saved and/or built. I was able to add a new EF model at this point.

 

Interesting that I also have Productivity Power Tools. One thing I did out of the ordinary is rename my Solution and solution folder (also deleted my old <Solution>.suo file).

Answer 5

I had this same issue:  Installed Power Productivity tools, then Ria Services and EF 4.0 broke. 

To resolve, I set the target framework for the web project to 3.5.  Save/rebuilt, then changed it back to 4.0 and all is well.

Answer 6

I had the same problem but two of my assemblies were not found

System.ServiceModel.DomainServices.Hosting
System.ServiceModel.DomainServices.Server

I 'browsed' to the GAC_MSIL added them, all fine

<!-- /* Font Definitions */ @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4; mso-font-charset:0; mso-generic-font-family:swiss; mso-font-pitch:variable; mso-font-signature:-1610611985 1073750139 0 0 159 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-parent:""; margin-top:0in; margin-right:0in; margin-bottom:10.0pt; margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:Calibri; mso-fareast-font-family:Calibri; mso-bidi-font-family:"Times New Roman";} @page Section1 {size:8.5in 11.0in; margin:1.0in 1.25in 1.0in 1.25in; mso-header-margin:.5in; mso-footer-margin:.5in; mso-paper-source:0;} div.Section1 {page:Section1;} --> Changing the framework to 3.5 and 4.0 is the only solution which I found while facing similar situation. It might help you too!

Since the Productivity Power Tools are being incorporated into Visual Studio 2011, I logged this bug on Microsoft Connect.  Up vote it if you also have this problem:
