EF Core 2.1 - 处理并行异步方法的连接

Question

I have multiple async methods in my DbContext to call stored procedures. All those methods handle connections as below.

        DbConnection connection = this.Database.GetDbConnection();
        bool needClose = false;
        if (connection.State != ConnectionState.Open)
        {
            connection.OpenAsync();
            needClose = true;
        }
        }
        try {}
        finally
        {
            if (needClose)
                connection.Close();
        }

I'm calling some of these methods in parallel. My connection string has MultipleActiveResultSets=True. I'm getting below error because the connection get closed by another method.

Invalid operation. The connection is closed

What would be a better approach for this? Thanks in advance.

Currently I'm closing the connection on dispose. It looks good. But if you have any other suggestions please let me know.

    public override void Dispose()
    {
        DbConnection connection = Database.GetDbConnection();
        if (connection.State != ConnectionState.Closed)
        {
            connection.Close();
        }
        base.Dispose();
    }
