• Register a user. you will get the database error page
• Apply Migrations does not apply the migration but results in an error
  

[rustd]

@rowanmiller FYI

Waiting on #4733 to be merged/built so that we can debug this one further.

[divega]

My understanding is that this is also blocked on #4953. I will assign it to @natemcmaster while we wait for that one to be addressed.

[natemcmaster]

@rustd do you have a version of templates and a recent version of dotnet-cli that work together? I'm trying to reproduce with dotnet-cli 1.0.0-beta-002351

[rustd]

@phenning?

[phenning]

You should be able to repro with the latest bundle build.

[natemcmaster]

The source of the bug is two fold.

1. The error is triggered because there is no database. In the error above, there is no DB yet, which is why "login failed".
2. The apply migration button executes a command that returns HTTP 404.

cc @JunTaoLuo @Tratcher are there known issues in diagnostics.entityframework? It appears UseDatabaseErrorPage() isn't working.

[Tratcher]

There's nothing filed.

[natemcmaster]

@Tratcher @rustd my guess is the bug here is in Diagnostics.EF, not EF itself. The request sent by the "Apply Migrations" button never reaches EF. The request gets lost in middleware.

[rustd]

@divega who owns Diagnostics.EF and who can fix this?

[divega]

This is @rowanmiller's. Will ask @smitpatel to look at it if @rowanmiller cannot do it tomorrow.
