Using custom grouping operators in LINQ (tomasp.net)

submitted by tomasp(160) 2 days, 15 hours ago

In LINQ, we can group data using the "group by" clause. However, there are other potentially useful implementations of grouping. For example, we may want to group only adjacent elements or group ascending or descending parts of the data. This article shows how to use custom behavior when grouping data using "group by" in LINQ query. read more...

submitted by CraigStuntz(425) 20 days, 19 hours ago

The Missing LINQ - Beware of Generated Code (www.codecapers.com)

submitted by mceranski(115) 26 days, 19 hours ago

LINQ (Language Integrated Query) to SQL is a great tool because it allows developers to concentrate on business problems instead of worrying about writing SQL. Unfortunately, generated code typically comes with a catch. My general rule of thumb is that "I never trust any tools that have a wizard or generate code". After all, everytime you release code into production you are putting your reputation on the line. Therefore, don't you think it is important to know what your code is really doing under the covers? read more...

Projecting Onto a Presentation Model with the Entity Framework and ASP (blogs.teamb.com)

submitted by CraigStuntz(425) 1 month, 4 days ago

In this post, I will demonstrate how to map entity models to views in an ASP.NET MVC application without worrying about implementation details like eager loading, lazy loading, or having to manually optimize SQL for the task at hand. I will argue that expressing the relationship between an entity model in the presentation model in a LINQ projection is far simpler than other methods of doing this mapping. read more...
