Consume Web Services from Metro Apps C#

Question

Hello,

I am trying my hands on Metro Applications,

I was trying to consume web service (WCF) and I tried these two codes :

For this one, i got exception : Unable to connect to remote server. But i m able to see the response when i hit the same url on the browser.

For this one, i got exception : "An error occurred while sending the request."

how can i consume a web service in metro app using C#.

a code sample would be appreciated.

Thanks in advance.

Hi Matt..

I tried that sample, but didn't help.

So, i tried consuming soap client using the url "http://wsf.cdyne.com/WeatherWS/Weather.asmx".

By this way, i m able to get data.

So, i tried consuming my Web Service:

But it gives exception while getting response. The exception says: There was no endpoint listening at http://myipaddress/myservice.asmx that could accept the message. This is often caused by an incorrect address or SOAP action.

InnerException: An attempt was made to access a socket in a way forbidden by its access permissions.

Also, when i try consuming the same .asmx service (by soap client) from .Net Framework 4.0 Application, it successfully gets the data. But when i try it from VS 2011 beta on Windows 8, it gives the above Exception.

Is this a problem of .Net Framework Version? or some system settings?

Please reply..

Do you have "Private Networks (Client & Server)" enabled in the manifest?  Also, if it's a local web service (hosted on same machine), be sure that "Allow Local Network Loopback" is enabled in the project properties.

I had the same problem, it also was the "Private networks (Client & Server)" checkbox. Tahnks a lot :)
