Peter returns to improve performance by splitting a single table into multiple entities, but this time, he implements his solution using the Entity Framework 6 designer.
There are some occasions when using Entity Framework can really hurt you: When you have tables with hundreds of columns or tables with large payloads. Here's how to get EF6 to do the right thing.
The critical part of security isn't your code; it's the people using your applications. Because of that, increasing your security often makes your applications less secure.
Here's an article about managing transactions that you don't need to read because, with one exception, Entity Framework will do the right thing by default. But, in the .NET Framework 4 and later, you can do more (if you ever need to).
You want the responsiveness that asynchronous programming in the Microsoft .NET Framework 4 provides, but also need your asynchronous methods to work with other code in your application. Here's how the Task object answers all of your problems.
Extension methods provide a great way for extending a class functionality -- but it's interfaces that let you use those methods anywhere you want.
An interaction script bridges the gap between designing concepts and actually adding controls to forms. The interaction script will tell you what your application needs to do, leading you (finally) to what controls you need on which forms.
The principles of great UI design start from a different place than the principles that lead to great application design. They both end up in exactly the same place, though.
The best thing you can do in order to create a great UI is to stop thinking about UI design.
You can completely disconnect your test code from your database with Entity Framework 6 in .NET and Visual Studio. You just need a little bit of custom code for your application, along with some boilerplate code.
Thinking in terms of layers or tiers really isn't much help to you. Stop doing it: The single responsibility principle and design patterns are all you really need.
Prune your Entity Framework with the help of asynchronous methods.
Entity Framework 6 gives you a variety of ways to call stored procedures that return data and capture the results those procedures return. Here's a look at all of them.
When you implement the Model-View-ViewModel pattern you need to tell your View (in this case, a Windows Form) when the ViewModel has new data. Here's how to do that, along with a warning about how to avoid a potential bug.
Peter Vogel moves a Windows Form to a modern design pattern, which forces him to think about how his code should be divided up among his classes. In the end, he comes up with some rules for making those decisions.
