I added
public override void Up()
{
CreateTable(
"dbo.Providers",
c => new
{
Id = c.Long(nullable: false, identity: true),
ProviderName = c.String(nullable: false, maxLength: 128),
Guid = c.Guid(nullable: false)
})
.PrimaryKey(t => t.Id);
}
public override void Down()
{
DropTable("dbo.Providers");
}
run in package manager console update-database db not updated. error still present.
