If you have recently downloaded the new Async CTP you will notice that WCF uses Async Pattern and Event based Async Pattern in order to expose asynchronous operations.
In order to make your service compatible with the new Async/Await Pattern try using an extension method similar to the following:
{
public static Task<DateTime> GetDateTimeTaskAsync(this Service1Client client)
{
return Task.Factory.FromAsync<DateTime>(
client.BeginGetDateTime(null, null),
ar => client.EndGetDateTime(ar));
}
}
The previous code snippet adds an extension method to the GetDateTime method of the Service1Client WCF proxy.
Then used it like this (remember to add the extension method’s namespace into scope in order to use it):
var dt = await client.GetDateTimeTaskAsync();
Replace the proxy’s type and operation name for the one you want to await.
