Metro app development hidden gem: anonymous type binding

Method ~ of ~ failed — Tue, 10 Apr 2012 00:00:00 GMT

Just a little post to point out a hidden gem if you are a .NET developer creating a Metro style app: you can bind to anonymous types. This came up in a discussion with a customer today that I was having and, frankly, I never tried it until then because my mind was back in Silverlight where this isnt possible. There may not be a tone of cases where this is valuable for you, but knowing it is there may help. Lets assume I have a basic class Person: 1: public class Person 2: { ...

Avoiding NotSupportedException with IQueryable

K. Scott Allen — Tue, 20 Mar 2012 00:00:00 GMT

Most remote LINQ providers can handle simple projections. For example, given a Movie class with lots of properties, and a MovieSummary class with a subset of those Movie properties, you can write a LINQ query like the following: var summaries = db.Movies.Select(m => new MovieSummary{ Title = m.Title, Length = m.Length }); But it all falls apart if you try to offload some of the work to a MovieSummary constructor. var db = new MovieDataStore(); var summaries = db.Movies.Select(m...

What’s Coming in JustCode Q1 2012

the telerik blogs — Sat, 11 Feb 2012 00:00:00 GMT

The Q1 2012 release webinars are just around the corner, and we will be showing off some cool new features in Telerik JustCode. Here are the session details, be sure to check your schedule! Note: well be giving away a Telerik Ultimate Collection.

Whats New in Tools for Better Code JustCode, JustMock, JustTrace, JustDecompile

We have many exciting features to introduce for Just products in 2012 Q1. JustCode gains LINQ conversions, enhancements to the test runner, and support for QUnit and Jasmine. JustTrace makes it easier to find memory hogs with the Largest Memory Retainers view. JustMock gets a codeActivity workflow activity for Team Build. Finally, JustDecompile is officially out of beta!

February 21, 2012
9:30 10:30 AM EST

This session abstract only gives a tiny taste of whats coming in this release. Some of these have already been covered in a blog post covering a recent internal build.

Naming Conventions

JustCode keeps your code clean, and weve added the capability to enforce naming conventions as part of the Code Style feature. There are seven types of rules you can apply: camelCase, PascalCase, UPPER_UNDERSCORE, lower_underscore, Sentence_underscore, PascalCase_UnderScore, and camelCase underscore. When a rule is violated, JustCode will show a warning. The quick fix menu will give you the option to rename is according to the appropriate rule.

More Code Style Features

Naming conventions may be the big news, but weve added other enhancements as well. You can now preview the effects of making changes to the formatter settings. Weve also split the XML code style settings into three parts: XML, XAML, and HTML.

Type Code Completion

Looking for a type but dont know the namespace? Press ctrl+alt+shift to bring every type referenced, regardless of the namespace. Start typing the name to find the type youre looking for.

Visual Aid

New options have been added for the Visual Aid, and a Visual Aid menu under Options | Visual Feature contains all the options in one location. Weve added new options as well, making the experience for mouse users more customizable.

Linq Conversions

Do you want to quickly switch between LINQ and loops? With the new LINQ conversions, you can quickly convert from query expressions to foreach loops or the extension method syntax. You can transform a loop into a LINQ expression.

Test Runner

Support for NUnit and MbUnit has been expanded to cover a few new attributes used in these testing frameworks. But the big news is we added support for QUnit and Jasmine! Now you can run your .NET and your JavaScript unit tests from one test runner.

Tons of New Quick Fixes, Refactorings, etc.

Of course!

Improved Decompiler

The decompiler in JustCode is basically JustDecompile integrated into Justcode. Described more accurately, its two tools, one engine. JustDecompile just had its engine replaced with one more powerful and accurate than ever before. JustCode gets this as well.

JustCode Extensions

This one has been under wraps, but Deyan Varchev discovered the project template that came with a recent build. Heres the screenshot he posted to YFrog.

The JustCode API has been available for a long time: you can think of the features you use in JustCode as extensions to it. But now weve release official templates for you to create JustCode extensions. There are many powerful things you will be able to do with this.

Conclusion

There will be four products covered in this webinar, and there are many exciting features for each. Be sure to register today for Tools for Better Code!

Moving Beyond Enums

Steven Smith — Tue, 30 Aug 2011 00:00:00 GMT

I just published an article on ASPAlliance on Moving Beyond Enums, describing when and how to move from enums to classes in your code when you start demanding more from your enums than they were designed to give. Check it out and let me know what you think. I also thought Id post an alternate LINQ-ified version of the DisplayFriendlyNames() method I used in the article.

Original, non-LINQ version:

public static string DisplayFriendlyNames()

    var sb = new StringBuilder();

    foreach (Role role in Role.List())

        if (role.IsVisible)

            sb.AppendLine(role.Name);

    return sb.ToString();

LINQ version:

public static string DisplayFriendlyNames()

    var sb = new StringBuilder();

    Role.List().Where(r => r.IsVisible)

        .ToList()

        .ForEach(r => sb.AppendLine(r.Name));

    return sb.ToString();

Its up to you which one you prefer. I generally prefer eliminating if-then conditionals wherever possible, and using LINQ for filtering. Note the .ToList() above is needed simply to be able to use .ForEach(). You can read more about why this is necessary on Eric Lipperts blog, where youll also find an IEnumerable<T> ForEach<T> extension method.

Lazy Exceptions for Fake LINQ Queries

K. Scott Allen — Wed, 22 Jun 2011 00:00:00 GMT

If you want to simulate an exception from an IQueryable data source, be careful about when the exception is thrown. As an example, let's use the following interface. public interface IContext { IQueryable<Person> People { get; set; } } To simulate an IllegalOperationException from the data source, you might setup a mock with the following code. var mockContext = new Mock<IContext>(); mockContext.SetupGet(c => c.People) .Throws<InvalidOperationException>(); But,...

We have IQueryable, so why bother with a repository

Pablo M. Cibraro (aka Cibrax) — Thu, 05 May 2011 00:00:00 GMT

The repository pattern became popular a couple of years ago by the hand of Eric Evans with the DDD (Domain Driven Design) movement and Martin Fowler with his catalog of Enterprise Application Patterns. The idea of having persistence ignorant entities inferred from the business domain and a repository as a simple intermediary for abstracting the underline persistence storage details had a great acceptance in the development community. No matter if you decided to stick to DDD or not, the repository...
