C# windows client app hanging while calling SP web Service

vikram padigala

Hello there,

My application users are intermittently facing application hanging issue.

In our analysis, we found that this is happening while calling SharePoint 2010 web service from C# Windows form application.

Details of the Application and Issue:

1. Application is developed on .NET 3.5, C# windows Forms

2. Application try to communicate with SharePoint for downloading and uploading the documents into SharePoint libraries.

3. Some of the SharePoint libraries have already crossed the list threshold, and i think this should be a problem.

4. Considering the issue from Network point of view, we have run the Network analyzer(Wireshark) on user machine, but no luck.

5. Looks like Application is waiting for the response from the SharePoint web service, and it never gives any response and application getting stuck here.

Please provide your valuable suggestion for my problem

Thank you in advance

Vikram

As Amit pointed out, try doing the web service operation in async method, ideally, it whould not halt the UI.

If you have tried something, please share some code so that we can understand the issue.

Meanwhile, try running Fiddler (in parallel) to see how much time request takes to get response back from server (Also check if there is some sort of proxy setup for each incoming/outgoing traffic through firewall). Fiddler should be helpful here.

Can you share the piece of code on which you had implemented threading to look at it.

Using threading or Task will definitely help you perform smoother operation without freeze your UI.

If it using web services or uploading/downloading files then use threading or async concept here to perform operation smoothly.
