EntityTypeBuilder does not contain a definition for ToTable in EF Core

Question

I have this sample code:

using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Metadata.Builders;
using Models;

namespace MySampleNamespace
{         


        

Answer 1

For EFCore 3.1 I needed to use this in my DB context:

protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        foreach (IMutableEntityType entity in modelBuilder.Model.GetEntityTypes())
        {
            entity.SetTableName("WS_" + entity.GetTableName());
        }
    }

No additional Nuget package was required.
