EF 4.1+ POCO, Repository and Specification Pattern Framework

Tue, 22 May 2012 13:49:15 GMT

I've been playing around with Code First EF implementations for awhile now and by far the best implementation I've seen is a framework by Huy Rua. It has the following functionality baked in: True Separation of Concerns for entities (no need for a data annotations dependency). A Generic Repository. This should do the trick for 80% of your standard CRUD operations without the need for repo's per entity. Supports multiple DbContext's and builds them dynamically. And finally a straightforward Specification pattern implementation. I use it as a base data layer for all my projects.

Begin with Parallel programming in Dotnet 4.0

Sat, 22 Jan 2011 00:59:59 GMT

Now a days computers are coming with multiple processors that enable multiple threads to be executed simultaneously to give performance of applications and we can expect significantly more CPUs in near future. If application is doing CPU intensive tasks and we find that one CPU is taking 100 %usage and others are idle. It might be situation when one thread is doing cpu intensive work and other threads are doing non cpu intensive work. In this case application is not utilizing all CPUs potential here. To get benefits all CPUs Microsoft launches Parallel Programming Library in DotNet Framework 4.0.

Entity Framework: Intro to Model First Design

Mon, 03 Jan 2011 20:38:28 GMT

Taking a look at how to use the Entity Framework via its model first design concepts. When building out an application which is based off of the Entity framework you have multiple options, you can either build your model off of your existing database or build your database of your existing model. This episode will explore how you start with your entity model and build out your databas

First part of this post will introduce the Entity Framework 4.0, its features and its comparison to Entity Framework 3.5

.NET CF Performance Best Practices

Tue, 09 Feb 2010 01:22:57 GMT

The impact of performance is much more readily apparent in .NET Compact Framework applications. The mobile devices commonly have a CPU that is 10 times slower than your desktop CPU, and possibly up to 100 times less RAM than a desktop or server. In Agile or XP development, the mantra is often to ignore performance considerations until necessary - I don't think you can apply that to .NET CF...

Parallel LINQ (PLINQ) with Visual Studio 2010

Tue, 03 Nov 2009 01:12:58 GMT

On the last day of May I wrote about how to calculate prime numbers with LINQ in C#. To close that post I said that I'd use the primeNumbers delegate to evaluate PLINQ (Parallel LINQ) and measure the performance gains when the same calculation is done in parallel instead of in a sequential fashion. As promised, today I show the performance gains when the same delegate is run in 2 cores (parallel) instead of only 1 core (sequential). In this post you'll also see the new parallel debugging windows that come with Visual Studio 2010: Parallel Stacks and Parallel Tasks.

.NET continues to DoS attack me, seriously!

Wed, 05 Aug 2009 20:45:00 GMT

Yeah, it does! And I don't necessarily mean denial of service - that would mean that I couldn't get any programming done. Nope, far from it - but it sure is denial of sleep attacking me. Come one, I am struggling to keep up with all the new runtimes, features, frameworks and best practices coming out of Redmond. It's awesome and actually fun; no doubt about it - but sometimes it is excruciating as well. And today I am going to talk about the excruciating experience of seeing another reinvented wheel hobble out of Microsoft.

Implementing Business Logic with Entity Framework

How you can use Entity framework to do some basic logic when a change happens in related entities or "Associations" as it is called. And Example on how to update of an Order's Total Amount when its Order Details get changed, Added or deleted using Entity Framework.

TNValidate - A Fluent Validation Library for .NET

Tue, 12 May 2009 11:32:50 GMT

TNValidate is a fluent validation library for .Net. It allows you to write validation logic in a form that is readable both by programmers and non-programmers, but still entirely in your .Net language. TNValidate has plenty of built-in validation rules, but also provides an extension mechanism to allow you to easily add your own without having to modify the library itself. The library is released under the MIT License.

EntLib 4.0 - ExceptionPolicy.HandleException is not thread safe

Wed, 06 May 2009 07:28:38 GMT

We've faced this problem recently where Enterprise Library was crashing. Not everywhere... just on this little line of code. We were trying to save to a database asynchronously but if the database was not available, it threw an exception which Enterprise Library was supposed to catch. However, this never happened. Enterprise library crashed on us. Mind you, we didn't figure out this problem until recently because the problem was just happening in production.

A quick review of different UI frameworks

Sat, 25 Apr 2009 18:21:50 GMT

This post reviews several frameworks used for creating graphical user interfaces. I've decided to create such a review after noticing many programmers take a specific GUI framework for granted, as it is their automatic-choice-by-tool (i.e., they use what they're IDE let them, barely understanding the layers required to develop such a framework, and that there are alternatives they might have chosen if they had knew about).

Aggregator Provider Pattern: White Paper and Samples

Fri, 10 Apr 2009 20:01:02 GMT

Provider Aggregator Pattern is an extension of Provider Pattern, which enables us to create and utilize multiple instance of the class having the same provider interface. In this pattern, there is an Aggregator class which implements the provider interface and contains a collection of instances of classes having the same provider interface.

5 reasons why you should use ASP.NET MVC

Mon, 06 Apr 2009 20:01:03 GMT

I'll be fair with you readers. I've only toyed with the ASP.NET MVC framework. It looks great as of now but it's the first full blown MVC framework that we have that is backed by Microsoft. However, there is a lot of opposition nowadays that tend to be formulated like this: Why should I use ASP.NET MVC? WebForms works well. Other problems come from the lack of server controls. When a developer look at that and he then wonder why he should have to write HTML and Javascript when before he could have retrieved all that beautiful information with a simple postback.

Part 2 - Basic of mocking with Moq

Thu, 12 Feb 2009 09:30:07 GMT

As every mocking framework, except TypeMock which can perform differently, every mocked class can't be sealed and methods that need to be mocked need to be public. If the class is not inheriting from an interface, the method that are being mocked need to be virtual. Once this is cleared... let's show a simple example of a Product having it's price calculated with a Tax Calculator.

Part 1 - Introduction to Moq

Thu, 05 Feb 2009 04:24:08 GMT

This is the first post of a serie on mocking with Moq. I'll be giving a conference a .NET Montreal Community on February 25th and I though there it would be good reference to anyone attending the @Lunch event.
