I have a considerable amount of experience with ACE, Boost and wxWidgets. I have recently found the POCO libraries. Does anyone have any experience with them and how they compare to ACE, Boost and wxWidgets with regard to performance and reliability? I am particularly interested in replacing ACE with POCO. I have been unable to get A...
I am building a WPF application using the MVVM pattern. Our stack looks like this: SQL Server 2008 -> Entity Framework We use StructureMap for dependency injection to inject our DataFactory which essentially does the CRUD for our POCO business objects. The ViewModels use the DataFactory for CRUD and the xaml is data bound to the prop...
I'm intrigued by this answer from another SO thread, and I was hoping someone can help me shine some light on the concept. Say I have a primary AppDomain and a bunch of child AppDomains, that are created and initialized by the primary AppDomain. In pseudo code: Primary AppDomain: class Parent { public void InitChildren(IList<Child...
Hello, I'm developing an application that needs to interact over FTP. For this communication I am currently using C++, Visual Studio and Poco on Windows. The following line results in a bad_alloc exception... ftp = new FTPClientSession("127.0.0.1", 21); So I went down and tried initializing a StreamSocket first, also fails... Stream...
Its often a requirement to have a domain object displayed in various ways on the UI; lists, search results, view and edit pages, as well as in headers, footers and popups. Typically you have several different "views" of the domain object, each with different fields displayed. Most advice seems to be to use a DTO to get the data when you...
I was looking at the differences between POCO and DTO (It appears that POCO's are dto's with behaviour (methods?))and came across this article by Martin Fowler on the anaemic domain model. Through lack of understanding, I think I have created one of these anaemic domain models. In one of my applications I have my business domain entit...
Reading about the lack of persistence ignorance in Entity Framework I often stumble upon POCO Adapter. The question is, does anyone use it in production, how does it go and what are the pitfalls? I consider two alternatives for the application design: use POCOs with that adapter in business logic and make the presentation layer use them...
I have seem many articles about POCO. What is this? ...
Hey there, I want that my unit tests to cover my POCO's. How should I test them? What If I add a new property? How to make my test fail? Testing the properties and methods I know, but the problem is, how to make sure my tests fail is anything is added to my poco's. Cordially, ...
There is some discussion on my team about updating entity data and how best to approach it. This is a security framework and so here are some of the constraints and ideas. every table in DB has a PK that is a guid, this is required for our multi-node clustering solution. The idea is that we don't want to expose this on an entity to a ...

In my object model i have two classes Project and User. The Project class has a property IEnumerable<User> Members I am using an external xml map file for mapping linq to sql associations. I...
Suppose you have three tiers (with namespaces): User interface (App.UI) - calls business layer processes and communicates using objects Business layer (App.Core) - orchestrates processes and uses DAL layer using objects DAL (App.Data) - directly manipulates store and persists objects Let's say that you have User table and thus reflec...
Hi folks, I have a stored procedure that returns a number of fields, pew row. Is there anyway i can define the class which the stored procedure 'goes into', instead of it using the auto-generated class? The class i want the results to populate is a POCO, not another LinqToSql table. Is this possible? i'm assuming that the poco class p...
Does the xsd.exe tool provided with Visual Studio generate the SchemaLocation attribute (in the xs:import) when generating XSDs from plain old C# objects? I am finding that my XSDs that were generated are not valid because the xs:import will import a namespace and not provide the relative schemalocation value prompting the below Imp...
I have been working with the Boost libraries for quite some time. I absolutely love boost asio library for network programming. However I was introduced to two other libraries: POCO and ACE framework. I would like to know the good and bad of each. ...
I wish to make a POCO [Serializable] but not any other class members in its class hierarchy tree. I know there is [NonSerialized] which works only for fields, but is there any way to exclude them or choose specific members using [Serializable] on the POCO? ...
I want to write a POCO in XAML, and use a DataTemplate to display that object in the GUI at runtime. So far, so good; I know how to do all that. Since I'll already have a DataTemplate that can transform my POCO into a WPF visual tree, is there any way to get the Visual Studio designer to play along, and have the Design View show me the ...
I have some POCOs and there are corresponding persistence objects that do the CRUD. What is a good name for the persistence objects? I've seen people use the term "service objects" for these, but when I think service, I think WCF. Maybe "persistence objects" is the best, but I'd like to hear what other people think. ...

Here is mu POCO class: public class ProductSubcategory { public Int32 ProductSubcategoryID { get; set; } public Int32 ProductCategoryId { get; set; } p...
Hi there, simple question really, i was wanting to know what naming conventions anybody puts on there DTO / POCOS .... I didn't really want to prefix like hungarian notation.. i got away from that!. But my dtos naming are clashing with my actual returned object names and although they are in a different namespace its still a bit con...
