I'm new to WCF, RIA Services, and even Silverlight for the most part. I need to know how to increase the amount of data that I can pass back from a RIA service. I know that I need to create summary lists and I am being smart about how I request data. I can't use paging because I've archetected myself into a corner, and it would be way too much refactoring at this point. I just need to double the limit of data coming back. My requests are fairly small. How can I do this, and also why is this window so small?
I'm told that I just have to modify ServiceReferences.ClientConfig but I have no idea where or what that is.
If you're working with RIA services, you can increase limit of transferring data by increasing http request length. Add this to your Web.config:
< system.web>
< httpRuntime maxRequestLength="1048576" /> ...< /system.web>
By default this value is 4Mb
