I'm having the same issue today, importing the solution. What do you mean by deleting the ones "generated by code"? I have many webresources in my Solution that were imported in the original package

I don't think that the WebResource has to be in the solution in order to force this error. I think the duplicate key is detected on the database.

It is Dynamics 365 Trial Version - Unable to even EXPORT the Solution is worrying.

Any assistance you can provide would be greatly appreciated.

There are only Global Option sets and Entities in the solution. No Web Resources Created in the Solution yet.

RE: Failed to process metadata description - Name: EntityKey, ID:

Sometimes the webresources are the cause for this error.

If there are some parallel processes which creates webresources, it may happen that 2 webresources with the same name will be created. But you don't see them in the UI.

Usually I delete the webresources that were generated by code, until I can publish again.

Not sure if there might be some other cases, when this error is thrown.

Kind regards,
