When to use ConfigureAwait(false) in case of developing async routine

[Sudip_inn]

this below way i develop a async routine where i used async & await keyword. some one told me to use ConfigureAwait(false).

i need to know what is ConfigureAwait(false) ?

and when to use ConfigureAwait(false) ?

so please come with a small example which show me the usage of ConfigureAwait(false). please post a sample code. thanks

private async void button1_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("Section", typeof(string));
dt.Columns.Add("LineItem", typeof(string));
DataRow dr = dt.NewRow();
dr["Section"] = "Test1";
dr["LineItem"] = "Test2";
dt.Rows.Add(dr);

var task1 = GetData(dt);
await Task.WhenAll(task1);

List<BrokerData> _tmp = task1.Result;
}

private async Task<List<BrokerData>> GetData(DataTable Lidistinctdt)
{
List<BrokerData> Bogeylist = null;

await Task.Run(() =>
{
Bogeylist = Lidistinctdt.AsEnumerable()
.Select(row => new BrokerData
{
Section = (row.Field<string>(0)).ToString(),
LineItem = (row.Field<string>(1)).ToString()

}).ToList();
});

return Bogeylist;
}

public class BrokerData
{
public string Section { get; set; }
