IDbContextOptionsExtensionWithDebugInfo issue

[michaelmfranz]

What is not working as expected:

---

method: SqlServerDbContextOptionsExtensions.UseSqlServer("connectionstring");

---

Issue: spontaneously stopped working, looks like a missing type that it shouldnt be trying to use
as it has been merged 1/2 a year ago (issue #13238)

---

Exception message:

---

Message=Could not load type 'Microsoft.EntityFrameworkCore.Infrastructure.IDbContextOptionsExtensionWithDebugInfo' from assembly 'Microsoft.EntityFrameworkCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

@michaelmfranz This is a breaking change for 3.0. To use EF Core 3.0 you will need a database provider that has been updated for 3.0.

Note also that it looks like you have a mix of versions--some 3.0 preview versions, and some 2.2 versions. This is very unlikely to work correctly.

Hi, thanks for that, after I submitted this issue I noticed the very same thing and then I did upgrade and the result was the same. Luckily two days ago I zipped up my application and I will see if I can get that old version working with my newer code

ok, my dlls got all messed up, they are in sync now, i think i forgot one of them was preview and that stuffed me up

In my situation, I had my main project using the preview entityframeworkcore versions but I had a private nuget package that was using the current entityframeworkcore version so that stopped my project from being able to run, Once I upgraded the nuget package to use the preview versions, everything worked
