    • HttpWebRequest.KeepAlive and remote DataPortal

      WinRT app with CSLA 4.5.601.0 running on devices with WWAN hitting a remote DP in the DMZ (acting as a pass through to an internal app server). We're seeing occasional errors related to connections being closed: WebException: The underlying connection was closed: An unexpected error occurred on a...

    • Maximum number of properties allowed in WinRT object? (Adding the 59th property breaks DP method)

      Scenario: WinRT project with CSLA 4.5. I've come across a weird situation where when I add one additional property to a particularly large object, the object breaks when the DP_Create method is called. It doesn't matter what kind of property I add (bool, int, whatever). The object has 58 properties...

    • Re: Remove remote data portal for mobile apps?

      This is an old thread, but I'm curious whether it is still relevant today, specifically in the WinRT world within the enterprise where an n-tier (not SOA) approach is used. We're going to be deploying a WinRT app to sales reps running Win 8.1 Pro and will be managing the devices via SCCM. I'm...

    • WinRT MobilePortal to secured endpoint

      I'm trying to have my WinRT app connect securely to a remote data portal over https, for obvious reasons. Up till now I've been testing internally without SSL, but when I start to test using a secured address I get the following error: The provided URI scheme 'https' is invalid; expected...

    • Authentication for WinRT devices joined to a domain

      We will have tablets running Win 8.1 Pro that will be joined to the domain, and users will sign in to those devices with their network credentials; however, I don't anticipate them connecting to the network via VPN while on the road. Instead, I expect the app to hit our remote DP on the DMZ, which...

    • Custom Proxy Factory with WinRT in v.4.5.501

      I'm following the Using CSLA Data Portal e-book where it talks about implementing a custom proxy factory so that an app can support occasionally connected scenarios. The SL example project shows the custom class that implements Csla.DataPortalClient.ProxyFactory. This doesn't appear to be valid...

    • Re: Windows Phone 8.1

      Windows Phone 8 (Silverlight 8) has been supported since it came out. Windows Phone 8.1 (WinRT) support is in the latest beta and should be released in a couple weeks. The biggest issue I had to deal with for 8.1 is that there's no WCF support on the new client, so I had to write a new data portal...

    • Authentication for WinRT LOB app

      I've previously created a Windows Store app that used Azure Mobile Services for authentication, which made things easy. I'm now working on a native Win 8 app for my company, and our network/infrastructure folks aren't comfortable with me using Azure. For authenticating the clients over the...

    • CSLA & Azure Mobile Services

      Last year I wrote a WinRT app that uses CSLA in a typical fashion to store data on the local client . But the app mostly bypasses CSLA when syncing to Azure because I opted to do bulk transactions using the standard Mobile Services interface. In part, I did this because it seemed the easiest route to...

    • IsDirty == True unexpectedly

      [CSLA 4.5.3 in a WinRT app.] I've got a BusinessBase parent object that has three object properties: one BusinessBase, one BusinessListBase and one ReadOnlyListBase. When I save the view, my VM does the following: Model.ApplyEdit(); Model.MyBaseObject = await Model.MyBaseObject.SaveAsync(); Model...

    • Re: Caching mobile object in WinRT

      When you say 'cache' do you mean in memory or to disk? If you mean to disk, that's a little tricky because the serializer (MobileFormatter) is version sensitive in terms of the assemblies. So if you update your app code to a newer assembly version the cache will be unreadable. If you are...

      Im looking to Cache CSLA objects in WinRT, can I use the same serialization used to copy mobile object from the server to the windows 8 application? Is there an example of that somewhere?

    • Re: Broken Rule for 1 property

      By "Win8" do you mean WinRT? Some features of the WinRT runtime are more similar to Silverlight 2 than to modern XAML. As a result the PropertyInfo control uses the SL2 binding scheme because the modern binding scheme can't be implemented :( <csla:PropertyInfo Name="blah" Source...

    • Re: WInRT's WebAuthenticationBroker for Authentication

      I tried that and then changed my mind and tried to do the same as in the code that comes with the data-portal book, so basically I authenticate with the WebAuthenticationBroker and I send the token to the backend so I can get the username using CustomPrincipal.BeginLogin(auth.AuthenticationType, token...

    • Re: Peer to Peer WinRT?

      CSLA doesn't include or prevent the use of peer-to-peer concepts. It is neutral on the concept. I don't think you can host a receiver/server on WinRT, but maybe you can - I've never tried. If you figure it out, you should blog about it, because this is something I haven't seen documented...

    • Re: WinRT - call to async CSLA factory method causes delay in rendering

      I have had difficulties with initializing the model in the constructor, though in your code I'd expect it to work. But you can't mark a constructor as async, so you can't use await there. Because of this, the 4.5 ViewModelBase now includes an InitAsync method so you can do this in your UI...
