Exception while calling SignInManager.PasswordSignInAsync with npgsql provider about efcore.pg

So I managed to find a solution to this issue. I happened to be using the rc1-update1 docker image as a base and noticed that its version of mono is outdated.

I recreated the image based upon mono version 4.2.2.30 and my initial issue was solved.

To do this either recreate and rebuild the docker file or install mono in your own docker file after the initial from statement.

Here's the command needed, I skipped the HKP part as this is done in the initial ASP.NET image.

RUN echo "deb http://download.mono-project.com/repo/debian wheezy/snapshots/4.2.2.30 main" > /etc/apt/sources.list.d/mono-xamarin.list \ && apt-get update \ && apt-get install -y mono-devel ca-certificates-mono fsharp mono-vbnc nuget \ && rm -rf /var/lib/apt/lists/*

Hope this helps someone.

Did you ever get to the bottom of this? I'm currently affected and unsure on the best direction to take.

Closing for age, no longer seems to be relevant.
