<p>I am making a post from a .NET console app to a .NET web service.  I know that the timeout on the server side is 20 min, but if my client takes more than 100 seconds to post my data to that service then I get a timeout exception.  How would I tell my client to wait the available 20 min to timeout?</p>

on the client side, your webservice object has a timeout value. It should be pretty easy to set by going:
```
```
myServiceInstance.Timeout = 1200000
```
```
for 20 minutes
