Compact framework and web services

[Krudler]

Hi

I have a compact framework application that gets information from a web
service running on a server. It works fine until I enable ssl on the web
site. - I change the URL of the webservice in my cf app to https, run the
app and get the error "a native exception has occurred in ...." which occurs
as soon as the webservice is called.
I cant debug properly i just reach the webservice call and it crashes. there
are calls to any other methods on that line.

Are there any other setting that you need to apply before the web service
will work. I have search the web but cant seem to find much information on
calling ssl web services on the compact framework.

does anyone have any helpful links or information?

I was considering using wse but havent been able to find much information on
this either..


Thanks

There may not be too much in the way of calling web services through SSL
from the .Net CF framework, but there is for doing this from the .Net
framework...

For starters, the device will need to get the certificate of the secure
server...

Let me know how you get on.

I have tried your suggestion but it seems to make no difference.

other people seemed to have got an "Could not establish trust relationship
with remote server." error and trusting all the Certificates fixed that.

I cant understand why I am getting a native exception.

I have tried cutting down my app to just a single form which calls the web
service but no luck.

Are there any settings in iis that could be messing me up. I can browse the
webservice.asmx fine

Strange... What are the details of the exception?
