Efcore.pg: Release 2.0.0-preview2

[voat]

When upgrading a Core 2 Preview 1 application to Core 2 Preview 2 we started experiencing this exception using the PG lib. This occurs on both Windows and Linux.

Message:

System.TypeLoadException: System.TypeLoadException: Could not load type 'Microsoft.EntityFrameworkCore.Metadata.IRelationalAnnotationProvider' from assembly 'Microsoft.EntityFrameworkCore.Relational, Version=2.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'

Npgsql EF Core version 2.0.0-preview2 hasn't been released yet, and it's not possible to use preview1 with EF Core preview2 (they introduced significant API changes). You'll have to wait until a 2.0.0-preview2 version of Npgsql.EntityFrameworkCore.PostgreSQL released (probably very soon).

I'll post back here once this is released.

[MathiasKowoll]

It is already released

[roji]

@MathiasKowoll no, it's not. EF Core 2.0.0-preview2 has been released, but not the Npgsql provider. It should be out in the next hour or two.

[roji]

2.0.0-preview2 has been pushed to nuget, please let me know of any issues you come across.

[MathiasKowoll]

@roji I menat that it was release about EF ;) will test asap

[SleepyDeb]

I get this error while creating migrations:

[MathiasKowoll]

@SleepyDeb I fix that error upgrading npgsql to 3.2.4.1

[roji]

@SleepyDeb for errors about NpgsqlDesignTimeServices, please use version 2.0.0-preview2-final where it is fixed.

Thank you @roji for the work. All our unit tests are passing on this library on preview 2.
