    • DataAccess layer for Neo4j

      Recently I was introduced to Neo4j (graph) database and I would like to try it with CSLA.NET. In order to try I've a couple of questions Which data object manager (like ConnectionManager, ObjectContextManager, etc...) can I use? Do I need to modify any of the DalFactory.cs or DalManager.cs classes...

    • Dynamic Update Statements and Property Table Information

      Hi all! I have been working with CSLA for over a year now and have typically used the model of having insert, update and selection stored procedures. But for flexibility I had heard that there was a way that the objects could dynamically save themselves without doing a stored procedure. Is there a structure...

    • Re: Sharing a transaction via CriteriaBase?

      This is the reason for the various transaction/connection/context types in the Csla.Data namespace. I discuss their use in the 'Using CSLA 4' ebook, and they are specifically designed to "flow" connections/transactions between your DAL components without having to deal with the complexity...

    • CSLA unit testing MVC no DAL

      I'm new to CSLA, and also unit testing in general, yet I'm newly assigned to a project that uses CSLA and they want to now write unit tests for it, and I'm lost. The project is a ASP.NET MVC 3 (c#) application, with a csla library that has umm inline? dataportal methods. The actual data fetching...

    • CSLA and EF DBCotnext

      Hi, I am pretty new to CSLA and I am trying to introduce a BL on top of the already built DL. The DL is build using EF4.3 and the DBContext. I am starting to face some challenges but I am not sure whether it's due to a bad implmementation or an inherent incompatibility between the tools I am using...

    • Re: CSLA .NET Data Helpers for Windows Phone

      That is a good observation, and we should add appropriate support for SQL CE - I'll add this to the wish list.

    • Re: Unable to serialize...

      Is this .NET or Silverlight? I'll assume .NET, or you wouldn't have gotten anywhere at all. In .NET, the entire object graph must be serializable. That means the classes that define all the objects in the entire graph must be serializable. Any object referenced from a field must be serializable...

    • Silverlight CSLA - BO invokes DAL

      Hi All, I've just completed watching the CSLA Core and MvvM video series. We currently are utilizing the standard DataPortal_XYZ methods into an Silverlight application to retrieve our data but we want to move to utilize a separate DAL (BO invokes DAL) to have both DataAccess.MsSQL and DataAccess...

    • ObjectFactory with different types of BOs

      Hi everyone, Is it possible to use a single ObjectFactory class that determines the type of BO to operate on at run-time? There is a custom base class (e.g subclass of ReadOnlyBase<T>) that has the ObjectFactoryAttribute applied on it and all its subclasses should use the same ObjectFactory, unless...

    • Re: About Data Portal

      In a Silverlight app in local mode your DataPortal_XYZ method is responsible for making a callback to tell the data portal your data operation is complete. The DataPortal_XYZ method gets a callback parameter that must be invoked when your method is complete - including the case where an exception occurs...

    • Re: Fastest way to insert object graph on to sql azure?

      I would think one answer is to use a Web Role in Azure to host the data portal, so the SQL Azure interactions are "local" within the Azure cloud.

      hi everyone. I have a winforms app running through a wcfhost (app server), setup pretty much like the ProjectTracker example (csla 3.6.3) using csla authentication. The problem I'm having is that unless (on the client - using user accounts -> manage your network passwords) I store the user credentials...

    • Data access ebook FactoryImplementation Unittest fails on OrderEdit

      Hi I think there's a mistake in the FactoryImplementation of the ebook sample (v 0.5): Test.Library.Net.OrderEditTest.OrderEditGetOrderEditTest throws the exception that the DataReader runs still a command. Looking at the source code I think the exception is right ;-) In class OrderLineItemDal public...

    • Re: Manual Transaction with a plugable DAL

      Yes, the DAL manager for your concrete DAL implementation can open the connection and start the transaction with the transaction manager. All other code using the transaction manager on that thread will get the same transaction. You don't want your DP_XYZ code calling begin/commit/rollback though...

    • Manual Transaction with a plugable DAL

      Hi I'm stuck with a SQL 2000 DB but I'm using CSLA4. Because the database is old I'm going to have to use manual transactions right? Well I don't think transactionscope will work well a SQL 2000DB? I've read that I can use the TransactionManager object to help me reuse a connection...

    • Re: Is there any general advice on using CSLA with some ORM tool?

      For my part, I view all ORM tools as purely a data access technology or concept. Therefore, their use should be restricted to the Data Access layer, and none of their artifacts should contaminate the Business layer, much less the Interface Control or Interface layers. I use EF quite a lot, and it creates...

    • DataReader closed when returned to BO (Encapsulated Invocation)

      I'm referencing Chapter 4 of the DataAccess Csla 4.0 eBook. I like the idea of Encapsulated Invocation for my DAL but I'm using ADO.Net SqlClient and the readers are closed when they are returned back to the BO because of the using block in the Fetch method. Does anyone have a good solution to...
