BootstrapPackage did not load correctly VS 2010

I just ins开发者_如何学Ctalled VS 2010 v 10.0.30319.1 RTMRel on 64bit Win7 Ultimate and keep receiving the following error when I try to open a web project. I have repaired and reinstall but the issue persists. I am looking for resolution suggestions. Thanks

The 'Microsoft.Data.Entity.Design.BootstrapPackage.BootstrapPackage, Microsoft.Data.Design.BootstrapPackager, Version 10.0.0.0.... did not load correctly.

This was happening to me as well. In my case I installed Visual Studio on my D drive which is not my system drive. After reading a link found in ChiliYago's blog post I found that the root cause was that files were missing from %ProgramFiles%\Microsoft Visual Studio 10.0\Common7\IDE (Which is what the error message says).

In my case, the missing files were installed in C:\ProgramFiles (x86)\Microsoft Visual Studio 10.0\Common7\IDE and not D:\ProgramFiles (x86)\Microsoft Visual Studio 10.0\Common7\IDE. My solution was to copy the missing .dlls from the install directory on the C drive to the install directory on the D drive, and the error stopped happening.

I had previously installed an Express edition of C# and un-installed it before adding Visual Studio 2010, this may have contributed to the problem for me.

In my case, I Installed Entity Framework June 2011 and then uninstalled it. After this I had this problem.

Nothing found in internet worked and when I was going to format I found in the directory: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\CommonExtensions\ these 2 files:

Microsoft.Data.Entity.Design.BootstrapPackage.pkgdef

Microsoft.Data.Entity.Design.Package.pkgdef

Here is when VS 2010 is trying to load the library that cannot load.

I have another PC with Entity Framework 4.0, and it doesnt have these files, so I have moved them out to the desktop. Now Visual Studio is loading the project succesfully.

On the other hand, my problem also was that If I choose to hide the error message then Entity Framework 4.0 didn't create the .Designer.cs of the Model. then when I tried to add the Domain Service Class to the project, the context class didnt appear (but yes in another machine with the same project and same database).

Now that I have not the error message everything looks working good.

I hope it helps others because I have had this problem during weeks.

Best Regards,

Tried the uninstall and reinstall of Visual Studio 2010… Still that had the damn annoying message about the Missing Assembly.

Looked on the C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ Directory which only showed: Microsoft.Data.Entity.Design.DLL

Installed a LOT of Windows Server 2008 files (32 Bit OS) in regards to SQL Server 2008… ADO.Net, etc… STILL didn’t solve the issue! GRRRRRRR!

So I finally fixed the issue by reading between the lines. See the details below on how I resolved this issue…

This points to the MISSING Assembly: Microsoft.Data.Entity.Design.BootstrapPackage, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/VisualStudio/10.0/Packages/{7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB}

Renamed Key to: HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/VisualStudio/10.0/Packages/{7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB}-123

Problem Solved for now in Visual Studio 2010!

Hope this helps someone else resolve this issue!

I've managed to completely remove VS 2010 from my computer using official utility and then reinstall it. Problem disapeared.

1. From tools menu in VS2010 select Import and Export Settings...
2. Select the last option, reset settings.
3. Save them, why not :)
4. Select a canned default, such as Visual C#.
5. Post your differences here, so that you know what to re-enable, and Microsoft people know what needs to be fixed.

I've had same problem, i solved it by rapairing it from "Control Panlel" clicking "Change/Remove" and tan choosing "Repair". BTW i'm using Win XP but i think that uninstallers in Visual Studio are the same. So.. Good luck!
