Hi, I'm using the EF Power Tools Beta 4 together with EF 5.0.0 CodeFirst in VS2010.

For any action on the DbContext class (view read-only diagram, generate edmx, generate DDL) I'm getting the following error:

Unable to cast COM object of type 'System.__ComObject' to interface type 'VSLangProj.VSProject'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{2CFB826F-F6BF-480D-A546-95A0381CC411}' failed due to the following error: Schnittstelle nicht unterstützt (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

My DbContext derivate is contained in a C# Project that itself is contained in a solution folder inside my solution; may that be the problem?


(PS. I rate the extension 5 stars for what it *used* to do ;)

Thank you EF Team...!

I have been using EF power tools for quite a while and was excited when beta 4 came out, however, it has a few issues.

1) It doesn't recognize Visual Studio references that are links and expects an actual file instead. This was working in the previous release. :-(

2) Pregenerated views don't handle abstraction properly when the property marked as the primary key is also an identity column, however, it works fine for properties that are marked as a primary key but don't have identity turned on.

Reverse engineer needs to be able to select a subset of tables. It also should be able to deal with views that may not have a primary key. Another issue I've been having is that if you export an image or print from the EDMX while using the dark theme, the multiplicity labels (*, 0..1, etc) are rendered as light text and effectively become invisible. The workaround is currently to switch to the light theme, export the image, and then switch back.

I've only just started using EF Power Box, but it reverse engineering my rather large database worked a treat, saved me a tonne of time!

Starting with great features to help develop database more quickly!

Desperately needs the ability to select a subset of tables / views to import, ability to generate code that adheres to common C# conventions, and ability to generate annotation-only code.

Reverse engineer worked on my database of 13 entities that was created model-first in EF 4.0. It even put IsRowVersion() on my timestamp columns!

Note that it automatically downloads the latest entity-framework, which means it will grab an unstable RC version if you didn't explicitly download one first. (The tool should probably honor the user's last settings in Visual Studio's "Manage NuGet Packages" if possible)

Many of the negative reviews complain about things which have nothing to do with this tool. One complains it crashes when you have 1392 tables. That's not what the Entity Framework is for! Another is a problem with source control. Yet another is about generating views.

Doesn't work with ODP.NET 12c .Is there any support for Oracle ?

by BobTabor | September 20 2013

Great tool -- if that's a workflow you want to enable ... can't get it installed with Visual Studio 2013 Preview yet, unfortunately.

by FLAKO69 | September 18 2013

Great tool, but the reverse engineer needs a dialog to select specific tables, I tested the tool on a data base with 1267 tables and have to wait to much time to generate the classes, and after that, delete all the unnecesary files.

by ashrael | September 17 2013

Until you can select individual tables to add, I don't find this very useful.

I am writing a small app to view To-Dos in a database of 100 tables, and have to wait for all of those classes to generate, then deleting all of unused data, is challenging and a waste of my time. Please make these changes.
