Difference between await and Task.Wait

Anonymous User 5073 27 Dec 2013

First way:

var tds=SearchProcess();
await tds;
public async 
Task<XmlElement> SearchProcess()
{
}

Second way:

var tds= Task.Factory.StartNew(()=>SearchProcess());
Task.WaitAll(tds);
public XmlElement SearchProcess()
{
}

In above both approach any performance difference is there?

Hi Tanuj,

Task.WaitAll is blocking, while using await will make the containing method async. To wait for multiple tasks asynchronously you can use Task.WhenAll:

public async Task DoSomething()
{
    IEnumerable<Task> tds = SearchProcess();
    await Task.WhenAll(tds);
    //continue processing   
}
