I would like to be able to create a runtime proxy for a POCO, in the same style as I might in Java using the JRE or cglib proxying libraries. I've seen Castle DynamicProxy which looks like it fits the bill, but the documentation isn't great. I'm also surprised that this kind of thing isn't in the .Net Framework itself. Does anyone: K...
Say I've got a domain model created from C# classes like this: public class MyClass { public string MyProperty { get; set; } } Along with the model, I have defined repository interfaces classes for IoC. Now, I'm trying to turn this POCO domain model into a set of Entity classes using LINQ mapping. (This approch was recommended in a b...
We are experimenting with several different persistence layers for our current project. We are trying for a POCO/PI approach. One of our candidates is LinqToSql. I am following the work presented by Vijay Mehta in "Pro LINQ Object Relational Mapping with C# 2008", in which the POCOs and the mapping files are created by hand. I have t...
I apologize in advance if folks think this has been beaten to death. I've just spent the last few hours searching and reading many excellent posts here in SO but I'm still confused. The source of my confusion is DTO vs. DDD and repositories. I want my POCO domain objects to have the smarts, and I want to get them from repositories. But ...
Hi folks, I have a simple POCO class that contains the student's scores. eg. Math - 83% Engrish - 82% Chemistry - 81% Drama - 100% etc.. Is there a way (using linq?) that i could figure out the top 3 properties ordered by score? I'm assuming the final object will be an IList of an anonymous type, which will have two fields. Name (t...

I am maintaining an application which has been designed like this: messy code --abuses--> simplePoco (POCO data capsule) The data capsule is a simple class with lots of getters and setters (properties) It uses a DI framework and consistently use the IoC container to provide instances of the data capsule (lucky me!). The problem is, I...

I have two POCO classes A and B where B inherrits from A public class A { public int Foo { get; set; } } public class B : A { public int Bar { get; set; } } B is ment as an extention to A with additional information. I start by having an instance of class A A a...
Hi, I am using the EntityFramework POCO adapter and since there are limitations to what microsoft gives access to with regards to the meta data, i am manually extracting the information i need out of the xml.

Hi folks, a month ago I asked this question: Trying to find the top 3 properties of a POCO instance. Got an answer, worked well. Now, I'm trying to find the top 3 properties of a POCO object (like my previous question) but where each property has a WEIGHT. The value of the property comes first. The weight then comes in second ... if tw...
Hello. I'm looking for a way to serialize a POCO that contains some read-only properties. In some Google and StackOverflow searches, I've seen the following suggestions: use DataContractSerializer; or use SoapFormatter or BinaryFormatter; or replace my readonly properties by read/write properties; My classes are very simple, they loo...

I have 3 different types of data: images, videos, and audio clips. Each one has an associated GPS point, so I have a base class as such: public abstract class Data { public Latitude { get; set; } public Longitude { get; set; } } This is so I can plot everything on a map without worrying about what kind of data it is. However, ...

The problem I have is that I have my UI, Service Layer and Data layer... Currently the data layer also has the ge...
