My EF model was generated from my SQL Server database. I then generated a DomainService for RIAServices against the EF model. One of the entities is called "EntryCategories". The DomainService created this method: public IQueryable<EntryCategories> GetEntryCategoriesSet() { return this.Context.EntryCategoriesSet; } Since my user i...
Only at runtime do I know what to display in my Silverlight Grid control. The control will pull from a RIA Services DomainServices source. In the middle tier, I have to transform an EF database source into a shape consumable by the Grid but also made up of types that RIA Services support. Only at that point do I know how many columns and...

So i'm fairly new to both SubSonic and RIA Services. I've done the RIA walkthrough for the HR app and it all looks good, but I'm not quite about creating a DomainService base class for Subsonic. The samples here describe creating a custom base class for your DAL but I wondering if there was already anything out in the wild that did thi...
Hello. I'm rewriting an LOB application whose architecture is like this: Silverlight && Windows Mobile -> WCF -> Entity Framework -> Database.

I have a problem when using LINQ to set a where clause on a query in a domain service call. If I don't set a where clause it works just fine and I get my result back in my completed event (I have only implemented the eventhandler for the completed event to demonstrate my issue here). LoadOperation<User> load = _Context.Load(_Context...

This works fine on both my development machine and in the staging environment. 2) I created a custom LinqToEntities RIA service to get data from the database into my application. This servi...
I had a connection working but something changed and now the data isn't showing up. It is a simple query that worked before that just returns all entities. I put in break points on the LoadOperation call and it fires and gets 0 entities. I also put a break point on the service itself, and it does not break before the LoadOperation eva...
Our application is built in VB6 and delivered in a SaaS model via Citrix. Our subscribers must first authenticate to the Citrix Login Portal (AD) which gives them access to their applications. Each application has its own local user repository so except for where we've implemented some single sign on strategies, the user must enter a s...
