Can not open Entity Data Model designer

Question

Hi!

I've created an Entity Data Model with Visual Studio 2010 Beta 2 yesterday and added some entities to my model. Today I tried to open the edmx file, but it gets opened in the text editor of VS instead of the designer, and i can't find any way to open it in the designer.

I found this post (http://thedatafarm.com/blog/data-access/can-t-open-the-edmx-file-in-the-designer-here-s-the-workaround/), but it didn't help.

Thanks,
DM

Answer 1

Additional info: i tried to uninstall ADO.Net Entity Framework Tools Beta 2 then i reinstalled VS2010 Beta 2. Now when i open my solution, i get the following error message:
---------------------------
Microsoft Visual Studio
---------------------------
The 'Microsoft.Data.Entity.Design.BootstrapPackage.BootstrapPackage, Microsoft.Data.Entity.Design.BootstrapPackage, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' package did not load correctly.

The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by running the application together with the /log parameter on the command line, and then examining the file 'C:\Users\...\AppData\Roaming\Microsoft\VisualStudio\10.0\ActivityLog.xml'.

Continue to show this error message?
---------------------------
Yes   No

And now i can not even see the icon of the edmx file in the solution explorer.

Hi Daniel -

A few questions:

  * What version of VS did you have install?
  * What OS are you running?  Is it 32-bit or 64-bit?


Here's what I recommend: 

1.  uninstall VS
2.  After VS uninstalls, run the following commands from an eleveated command prompt:

REM
REM
REM Run these if you're running 32-bit windows
REM
REM
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\AutoLoadPackages\{adfc4e66-0397-11d1-9f4e-00a0c911004f} /v {7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} /f
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\AutoLoadPackages\{93694fa0-0397-11d1-9f4e-00a0c911004f} /v {7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} /f
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\10.0\Packages\{7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} /va /f

REM
REM
REM Run these if you're running 64-bit windows
REM
REM
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\AutoLoadPackages\{adfc4e66-0397-11d1-9f4e-00a0c911004f} /v {7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} /f
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\AutoLoadPackages\{93694fa0-0397-11d1-9f4e-00a0c911004f} /v {7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} /f
reg delete HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Packages\{7A4E8D96-5D5B-4415-9FAB-D6DCC56F47FB} /va /f 
 

3.  Re-install VS (be sure to choose to install C# and/or VB langauges, otherwise the EF Designer won't be installed. 


Let me know if this works,

Thanks,

Answer 3

Why am I receiving this same error with VS Ultimate RTMRel?????

Answer 4

Please notify me if anyone at MS cares to provide a solution that does not waste an hour of my time uninstalling/reinstalling.

Answer 5

I also got these irritating error messages about the BootStrapPackage, etc. and tampering with the registry (including a laborius unistall/reinstall) resulted in twice as much error messages for me.

Then I found this link about MVC Template not showing up in Visual Web Developer, and soon suspected a close connection to my problem.

So I followed these very simple instructions:

1. From the Tools menu, select "Reset all settings" and then "Next"

2. Choose if you want to save our old settings or not, then "Next"

3. Select "Visual C# Development Settings" (or our own preference) and then "Finish".

And thats all!

Hope this will work for you too.

Answer 6

Nope, did not work for me.

Answer 7

Worked for me. Thanks.

Answer 8

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 Connect people know what needs to be fixed.
