    • Re: Errors From Data Portal are all generic Async Error

      Not a bug, a feature :) It turns out that when you await a method that numerous things could occur within that method - even in parallel - and so it is possible for multiple exceptions to be returned. The only correct way to return exceptions from an async method is with an async exception - which is...

    • Re: How much async is too much?

      Remember that async usually does NOT mean multiple threads. It means concurrent IO. What you get from concurrent IO on a web server is really two things. First, the web server gets to reuse your thread when you code gets blocked by IO - at least that's my understanding. This improves the overall...

    • Wait for object to no longer be busy?

      I feel like I'm missing something simple. If you have a BO with Async business rules, how do you wait for the object to no longer be busy before carrying on with something else, such as asking the object to save itself? I would have thought there'd be some method to await the non-busy state,...

    • SaveAynsc and await

      We are currently saving our CSLA object with SaveAsync using the following syntax: Model = await Model.SaveAsync(); I am getting an error with Object marked busy cannot be saved. It seems to be busy with validation. Our thought is to override save async to look at isbusy if isbusy then it needs to listen...

    • Per-property authorization rule that depends on async, lazy-loaded property

      What is the best approach for implementing a per-property authorization rule that depends on the result of an async, lazy-loaded property? Here's my suggestion: [Serializable] public sealed class Parent : BusinessBase<Parent> { public static readonly PropertyInfo<string> NameProperty...

    • Re: How to handle exceptions on client side (e.g. UI)

      The CSLA books cover version 4.0-4.3. The data portal has changed _significantly_ in 4.5 because we now fully support async/await. The new async/await behaviors in .NET introduce some interesting exception handing issues, and I tried to handle them in a meaningful way. Because your DP_XYZ or factory...

    • Re: WCF Over WebSphere MQ

      I love your avatar graphic - SPOON!! :) The data portal only really requires a synchronous binding. But I'm guessing that the MQ binding is async, so it probably won't work, at least not easily. To put it another way, the client-side data portal proxy must appear to be synchronous. So you could...

      Hi, I am using CSLA 4.2.2 with Silverlight (love it). I have a question about the use of async rules. I have some BusinessBase objects I fetch from the database.There is the possibility the database data can be incorrect, so I want to call BusinessRules.CheckRules() from within DataPortal_Fetch. In this...
