dotnet ef database update fails unable to load Microsoft.Extensions.DependencyInjection.Extensions.ServiceCollectionExtensions

[akuseru]

This is possibly related to #48 & npgsql/npgsql#1171 however after updating npgsql to 3.1.5 I am still seeing the following:

System.TypeLoadException: Could not load type 'Microsoft.Extensions.DependencyInjection.Extensions.ServiceCollectionExtensions' from assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

perhaps waiting on a version bump to Npgsql.EntityFrameworkCore.PostgreSQL?

#54

[allangomessl]

@akuseru this error occurs because the class ServiceCollectionExtensions was renamed in Dependency.Injection RTM Version.
Then wait for update version of Npgsql.EntityFrameworkCore.PostgreSQL for RTM Version

Thanks 👍

Can you confirm whether you're still seeing this using Npgsql.EntityFrameworkCore.PostgreSQL 1.0.0 (just released) and Npgsql 3.1.5?

[julielerman]

wahoo!

so far so good. My app is running, building a db, populating it and I can interact.
Thanks for doing that so quickly! :)

[akuseru]

no issues here either. Thank you!

Thanks for the fast hard work roji.
