Does not work with IdentityDBContext (ASP.NET Identity framework)
When attempting to generate EDMX diagram:

Could not load type 'System.ComponentModel.DataAnnotations.Schema.IndexAttribute' from assembly 'EntityFramework, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Please fix it

Thank you

The best EF tool, forever

Should I be using the new 'Entity Data Model Wizard' for code first generation of an existing database ( http://msdn.microsoft.com/en-us/data/jj200620 ) instead of this tool ?

Hopefully can support VB project.

Works fine for me in VS 2012 Ultimate; however, the context menu for
"Entity Framework" does not appear when installed for VS2013 Web Express.

Fails with EF 4.4. Multiple exceptions. What versions does this even support?

try supporting this by adding virtual to the DbSets: http://msdn.microsoft.com/en-us/data/dn314429.aspx

by Gutek | March 03 2014

as for a product created by EF Team and MS, it should handle DB with dash in name.

I'm adding one start as this is completely unusable for me.

I've send a pull request for this issue:

Useful tool ever since first version. But why is the model "Read-only?"
Is the underlying XML re-generated constantly and read-only for that reason.
Guess I'm just remembering the old modeler for SQLCE in a Winforms project being a complete editor.
Was a pretty handy GUI tool.

BETA doesn't apear to have to fix for Reverse Engineer Code First when using SQL CE.

Unbelievable, only in C #?
The VB made ​​Microsoft what it is today, putting the software development within companies without "bit and bytes"'s specialists .
It is a shame that there is no longer a direction to a simple development where it's required so.

I don't know why Reverse Engineer function gives below error.

"System.ArgumentException: The modelEntityContainerName parameter 'asdf-dbContext' contains characters that are not valid.
at System.Data.Entity.Design.EntityModelSchemaGenerator.Initialize(EntityContainer storeEntityContainer, IEnumerable`1 storeFunctions, String namespaceName, String modelEntityContainerName)
at System.Data.Entity.Design.EntityModelSchemaGenerator..ctor(EntityContainer storeEntityContainer, String namespaceName, String modelEntityContainerName)
at Microsoft.DbContextPackage.Handlers.ReverseEngineerCodeFirstHandler.ReverseEngineerCodeFirst(Project project)"

Azure SQL and MSSQL VM on Azure both occurred.

Great tool, saves a lot of time, however:
1) it needs to be working as a background operation to prevent disabling visual studio for long periods of time.(2400 tables > 9 hours)
2) should have a dialog to allow the selection of target tables.
3) there is a bug with oracle composite foreign keys, the columns order is wrong, items need to be shifted 1 spot to the left( not always).

I ran into the error "There was an error loading the include file 'EF.Utility.CS.ttinclude'" today.

I was able to fix it by uninstalling and reinstalling the EF Tools off my Visual Studio 2013 install disc. E:\packages\EFTools\EFTools.msi

I've got the same problem as others... I want to connect to a database (testing connection is successful), but when I click OK in the connection dialog it shows me the following message:

Wrong paramter Exception (HRSULT:0x80070057(E_INVALIDARG))

I tried it at Visual Studio 2012 and 2013. It doesn't work. :( Hope you can help or fix it soon.

I'm trying to pre-generate views, but it only shows "Exception has been thrown by the target of an invocation" message on VS 2013.
On VS 2012 it works perfect with the same project.

Is there something that it's needed to be done for pre-generate views on VS 2013?

Thank you!
