Unable to create migrations after upgrading to .NET Core 3.0

[ury]

After upgrading my solution to .NET Core 3.0, I'm unable to create migrations when using the package.
When Add-Migration is executed, it results with the following error:

Method not found: 'Void Microsoft.EntityFrameworkCore.Migrations.Internal.Migrator..ctor(Microsoft.EntityFrameworkCore.Migrations.IMigrationsAssembly, Microsoft.EntityFrameworkCore.Migrations.IHistoryRepository, Microsoft.EntityFrameworkCore.Storage.IDatabaseCreator, Microsoft.EntityFrameworkCore.Migrations.IMigrationsSqlGenerator, Microsoft.EntityFrameworkCore.Storage.IRawSqlCommandBuilder, Microsoft.EntityFrameworkCore.Migrations.IMigrationCommandExecutor, Microsoft.EntityFrameworkCore.Storage.IRelationalConnection, Microsoft.EntityFrameworkCore.Storage.ISqlGenerationHelper, Microsoft.EntityFrameworkCore.Diagnostics.IDiagnosticsLogger`1, Microsoft.EntityFrameworkCore.Storage.IDatabaseProvider)'.

I've verified that this is related to the package: When I remove it (together with all its references) from my project, Add-Migration is completed successfully.

I am also having this issue.

I haven't played with .NET Core 3.0 yet and will "get my hands dirty" with it these days and will find out what's causing the problem and fix it.

Hi George
Firstly Thank you very much for your Project

I Updated my project to 3.0 but i receive the following exception
System.TypeLoadException: "Could not load type 'Microsoft.EntityFrameworkCore.RelationalMetadataExtensions' from assembly 'Microsoft.EntityFrameworkCore.Relational, Version=3.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'."
on
temporalTableSqlBuilder.BuildTemporalTablesSql();

Metdadata API has changed

Have you any Idea ?

Best regards

Thank you for being patient enough and appreciate the project.
