Getting "System.ArgumentNullException: Value cannot be null. Parameter name entityTypeBuilder" in RC2-16485 #4028

Can you post full stack trace? |
Have similar bug.

I tried to send an email as to see if I can send you the test project with my model that is failing. That way you can get the full error with all the states on your side. I just can't post the model here since it is based off a production model at work that I cannot put on a public issue forum. In the meantime, here is the stack trace that I have.

Apparently my guess at your email address was wrong. Edited to remove the email address. |
for both of the above cases - dupe of #3845 |
In which daily build should I notice the fix? I updated to 16533 today, and I still see the issue. The fix for #3845 looked to be merged in Friday. |
@emrs-jm - Build no. is 16536 |
How to get it? Unable to locate Dependency EntityFramework.MicrosoftSqlServer >= 7.0.0-rc2-16536

@ErikEJ thx! Useful repo link. |
I have a project a and a test project that uses my model that cannot run context.Database.EnsureDeleted() without crashing with the following error: System.ArgumentNullException: Value cannot be null. Parameter name entityTypeBuilder.
The model works in Beta 8, but throws an "InvalidOperationException: The derived type 'x' cannot have keys other than those declared on the root type." in RC1-final. I decided to try a RC2 nightly build since this issue seemed to be something that happened potentially related to one of the other issues where the bug appeared to be fixed #3727 and one not fixed #3863. I can send a smaller project that has this issue but I would want to send it directly since our model is closed.
Some additional background is that a subset of the model seemed to work in RC1-final, but it stopped working when I included the rest of model.
