Win CE with Web Service

[scsfdev]

Hi All,

May I check with you does any one has any answer for my below problem?

My problem in details:
I'm developing Win CE application in Visual Studio 2008 Professional Edition (TRIAL). The application was in CF.Net 3.5.
I can create the application run it on actual device without any error.
I have another project (Web Services) created in the same environment, VS 2008 Pro Trial edition. the application was also in .Net 3.5.
I can browse this web service from my browser. I can also use it on another WinForm (VS2008 Pro Trial) application without any error.
I can call and get the result in this WinForm. This WinForm application also the same .Net 3.5.

However, I can't use this web service on my Win CE aplication.
I don't know why and what happen. Please refer to attached picture file.
As you can see from my image, I can add Web service in win ce application but I can't call in my code behind to consume it.
I tried to add wsdl (http://ComputerName/testwsvc/service.asmx?wsdl) in address and add the reference, the result is the same, can't use it.

Right now, our company decides to purchase the license version since we will need to do some projects for CE applications but I can't tell them to buy VS2008 cuz I can't link up web service with CE application.
I also don't know which version I propose for purchasing.

I already asked the same question in MSDN forum but no body answer. I didn't want to ask here is because this forum seems to be mainly focused on VB.Net only. Sorry about that.


Please help me if anyone of you know the answer.
Thanks.
