After update to the new package Microsoft.EntityFrameworkCore.SqlServer 1.1.2 I got error when try to create DBContext:

My base DbContext

```
public class SqlServerDbContext : DbContext
{
    private readonly DatabaseOptions _databaseOptions;

    protected SqlServerDbContext(DatabaseOptions databaseOptions)
    {
        if (string.IsNullOrEmpty(databaseOptions.ConnectionString))
            throw new Exception("Database connection string is missed.");

        _databaseOptions = databaseOptions;
    }

    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer(_databaseOptions.ConnectionString);
    }
}

```

Database options that I use

```
public class DatabaseOptions
{
    public string ConnectionString { get; set; }
}

```

Place where I create instance of context

```
 var dbOptions = new DatabaseOptions { ConnectionString = _connectionString };
 DbContext = (TContext) Activator.CreateInstance(typeof(TContext), dbOptions);
// where TContext is derived class from SqlServerDbContext

```

All my packages are updated. Visual Studio 2017 15.2 (26430.6). Before upgrade to 1.1.2 everything works fine. Please help to solve the problem.
