Question

I am using the Memory Management while returning the data like below.

private DataSet ReturnDs()
{
    using (DataSet ds = new DataSet())
    {
        return ds;
    }
}

Query – Is there any issue in placing the ‘Using’ Statement while returning the data? I am Still getting the complete schema as well as the data in the receiving function?

This is definitely a wrong pattern. The only reason that it is working for you now is that DataSet.Dispose() is actually a dummy.

using (DataSet ds = new DataSet())
{
    return ds;
}  // there is a ds.Dispose() here but it does nothing.

If you replace the DataSet with for instance an Enitity framework DbContext then you would not see any data in the calling function.
