Entity Framework 4 Repository returning IList: What C# code could limit which POCO fields populate?

If you populate a drop down list of possible values, you only want the database query to pull two fields, a value and text (like customer ID and Name). However, your Repository returns POCOs, namely the entire Customer record. I wouldn't think you should create a POCO for every single DDL list you need, so how does one specify to a rep...

Using Poco XMLWriter with UTF8 strings in C++

I have a problem trying to get my head around using UTF8 with Poco::XML::XMLWriter. In the following code example, everything works fine when the input contains ASCII characters. However, occasionally the string in wordmapIt->first contains a non-ASCII value, such as a character -105 occurring in the middle of a string. When this happens...

Code First CTP4: How to map these two entities

A Team can have many matches, but HomeTeam and AwayTeam can only have one team each. Sometimes Team is a HomeTeam, and sometimes the same Team is an AwayTeam. I have provided just the basics for each of the classes: pu...

Now, here is some code i have in my UI to perform an UPDATE: [HttpPost] public ActionResult UpdatePerson(Person person) { repository.Attach(person); unitOfWork.Commit(); } Es...

Lazy loading a subclass from a POCO in Entity Framework 4.0

I was wondering if anyone has attempted to lazy load a subclass (where is isn't known what the subclass is until the result is returned) using EF and POCOs? This is a bit of a nightmare in NHibernate, but works as long as you don't attempt to cast the returned result to a subclass (because a proxy of the base class is created, it can't ...

Entity Framework POCO generator vs Entity names

Poco generator for EF 4 is great! it took me a while to figure out how to use my existing classes as POCO's but i did and it works. One thing i can't seem to still be able to figure out, is how to use the same class for 2 entities. Seems that the POCO class has to have the same name as the Entity it is going in place of, and not ju...
