EF Core bug requires sharing codebase with EF team #8142 | Support Center

tusksoft created 5 years ago

We've run into a bug with EF Core which appears to be in the EF Core team's court, not ASP.NET Zero's. The bug is documented here: https://github.com/aspnet/EntityFrameworkCore/issues/18178 It was supposed to be fixed with the 3.1.0 release which came out today, but we continue to experience the issue after upgrading Nuget packages. So far the only project we're experiencing this with is our ASP.NET Zero based solution at v8.0.0, and as such we need to share the codebase with the EF team.

How can we go about sharing the A0 codebase with the EF Core team without violating your license terms?

hi tusksoft

Since it is a problem with EF Core, I believe you can directly use EF Core's application to reproduce it without sharing zero code.

I have been unable to reproduce in a templated app. I can, however, reproduce in a pristine copy of A0 8.0.0. Could you or I provide a copy to their team behind auth challenge and share credentials privately? A demo app would be sufficient.

This bug is having a pretty severe affect on our workflow for an application we've just started working on so we really need to get this addressed. I'm not sure how to work around it in A0, and A0 is the only app we have that's exhibiting this behavior. If you all can find a workaround, we're fine with that as well. We just need it fixed for 8.0.0 to be a viable platform for us to move forward with.

Can you reproduce the problem using Zero's Demo project? If you can share the steps, I will try to reproduce it using a plain ef core application.

Yes, it can be reproduced in the demo project. In a pristine solution just run add-migration followed by remove-migration . You can actually skip adding the empty migration and just run remove-migration to achieve the same exception.

We've had to nuke ALL of the migrations that come with A0 and recreate them as a single migration in order to get things working properly. We're avoiding committing this change as it will create additional pain when upgrading the A0 framework.

In the github issue I linked to the problem was reported fixed, but the use case here does not seem to be covered by the fix. I would venture to guess that if the SQL Server column types were explicitly defined in the cs.designer files all would work as expected, but that requires a prohibitive time investment on our end and presents the same problem in terms of upgradability. This is something your team would need to do to maintain maximum upgradability of the framework.

One final note, I've tried to recreate this problem in a VS2019 templated project with no success. These were the steps I used:

Create project

nuke templated migrations

roll back EF related packages to 2.x versions and update context code as necessary to be able to run add-migration successfully (see https://stackoverflow.com/questions/45782446/unable-to-create-migrations-after-upgrading-to-asp-net-core-2-0)

add an initial migration

update EF packages to 3.1.x

run add-migration

run remove-migration

Thank you for the information, we will consider rebuilding all migrations or other solutions.

While our original issue has been fixed in the upgrade to 8.1, we now have another bug when adding new migrations. Here are the steps to reproduce this issue on a clean demo project of v.8.1:

Create project
Create new domain class
Add new migration

The migration adds the following column:

            migrationBuilder.AddColumn<int>(
                name: "EditionPaymentType",
                table: "AppSubscriptionPayments",
                nullable: false,
                defaultValue: 0);

Because of this column, running update-database produces the following exception:

Column names in each table must be unique. Column name 'EditionPaymentType' in table 'AppSubscriptionPayments' is specified more than once.

Here is the Stack Trace for the exception:

Applying migration '20200102200758_Add_User_With_Address'.
