VS 2017 15.8.0 & Entity Developer 6.3 upgrade issue...

[jorgeivancho]

Hi everybody...

I am having issues trying to open the .efml diagram in VS 2017 after upgrading to the latest version of VS 2017. I get the following message:

Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.Shell.Interop.IVsAggregatableProject'. The operation failed because the QueryInterface call on the COM component for the interface with IID '{FFB2E715-7312-4B93-83D7-D37BCC561C90}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).


I tried uninstalling the entity developer product (6.2.205), cleaning up all entries I could find of the devart product manually and after restart (with VS turned off) trying a fresh installation of the latest ED version (6.3.555) but the final result was the same error message.

I tried the same upgrade in another machine with the same version of VS and ED and the result was the same as well.

Any help will be appreciated.

Hi.

I have the same issue. - I have updated to 15.8.1 and the issue is also reproduceable here.

I have tried to reinstall devart and visual studio, but this did not fix the error.

I have found if I open the .lqml in the Entity Developer application and after that "Run custom tool", I am able to make changes despit the problem.

In VS 2017 15.8.0 and Entity Developer 6.3.569 I have still the same problem...

I can confirm that after upgrading my devart entity developer to 6.3.582 and running VS 15.8.4 I can get the entity developer diagram to open in VS again and code generation working as well with no issues.

Thanks for the fix.
