Why Is The Return Type Parameter Last?
The generic delegate type Func<A, R> is defined as delegate R Func<A, R>(A arg). That is, the argument type is to the left of return type in the declaration of the generic type parameters, but to the right of the return type when they are used. What's up with that? Wouldn't it be a lot more natural to define it as delegate R Func<R, A>(A arg), so that...Full Article.

Absolute positioning control(s) in the designer can seem confusing at first until you learn the visual cues. You can do one of the following two possible actions by dragging the control in the designer.

- Change the controls position.
When you drag the body of the control, you are changing the parent of the control. You can see this because the cursor changes to the small arrow with a square box.

Tip # 52: Did you know... When deploying your ASP.NET web application, debug=false should be set in web.config
To help troubleshoot problems, developers usually enables the debug mode in web.config file. This causes ASP.NET to produce extra information in the compiled assemblies such as debug symbols, metadata. However, performance will be suffered as it takes longer to compile and run, consumes more memory and resource caching is not performed. Therefore, in production, we should set the debugging option back to false to avoid the effect on performance. There are two ways to achieve this.

Tip # 52: Did you know... When deploying your ASP.NET web application, debug=false should be set in web.config
To help troubleshoot problems, developers usually enables the debug mode in web.config file. This causes ASP.NET to produce extra information in the compiled assemblies such as debug symbols, metadata. However, performance will be suffered as it takes longer to compile and run, consumes more memory and resource caching is not performed. Therefore, in production, we should set the debugging option back to false to avoid the effect on performance. There are two ways to achieve this.

RFC: C# in Depth 2nd edition, proposed changes and additions
As I've mentioned in passing before now, I've started working on the 2nd edition of C# in Depth, to roughly coincide with the release of C# 4 and Visual Studio 2010. So far I've just been thinking about what should be added and what should be changed or removed. That's what I'd like to share today, and I'm really eager for feedback. In particular, I'd like to think of three audiences:

Language proliferation
I've always been aware that .NET supports multiple languages (obviously) and that Microsoft has been experimenting with this to some extent. It's only recently struck me just to what extent this is the case though.
Here's a list - almost certainly incomplete - of .NET languages from Microsoft alone.
A different approach to inappropriate defaults
I've had a couple of bug reports about my Protocol Buffers port - both nicely detailed, and one including a patch to fix it. (It's only due to my lack of timeliness in actually submitting the change that the second bug report occurred. Oops.)
The bug was in text formatting (although it also affected parsing). I was using the default ToString behaviour for numbers, which meant that floats and doubles were...Full Article.

Add support for iPhone in ASP.NET
When I was building the mobile TV guide I found that there are a couple of things needed to make the website look better on the iPhone and iPod. They both have some extra capabilities that is easy to utilize when you know how.
Zoom level
The first is the zoom level. By adding the meta-tag below, you can specify the viewport to fit perfectly with the iPhone/iPod. The meta-tag tells the Safari browser to zoom in to a specific level as specifie...Full Article.

I tried. I really did. For five months I've chronicled my daily thoughts and activities for all to see. But despite my efforts, this really only confirmed what I suspected right from the start: that Twitter is really pretty pointless.

The BlogEngine.NET team worked very hard on those fixes and I believe they were all taken care of properly.

ASP.NET is a database framework
I have a very clear view on what ASP.NET is and what it isn't. I've never given it much thought until recently when I learned that my view was different from a lot of other ASP.NET developers'. It started at an ASP.NET session at the MVP summit where a presenter asked whether or not people in the audience used the Entity Framework or Linq2Sql. I thought to myself that data access had absolutely nothing to do with ASP.NET but found to my surprise I was the only one finding it a weird question ...Full Article.

My Little World Domination Backup

TipJar: Title Tags and Master Pages
There are a couple of peculiarities worth understanding when dealing with title tags and master pages within Web Forms and ASP.NET MVC. These assume you are using the HtmlHead control, aka <head runat="server" />.

Scripting ASP.NET MVC Views Stored In The Database
Say you're building a web application and you want, against your better judgment perhaps, to allow end users to easily customize the look and feel - a common scenario within a blog engine or any hosted application.
With ASP.NET, view code tends to be some complex declarative markup stuck in a file on disk which gets compiled by ASP.NET into an assembly. Most system administrators would first pluck out their own toenail rather than allow an end user permission to modify such files.

Donut Hole Caching in ASP.NET MVC
A while back, I wrote about Donut Caching in ASP.NET MVC for the scenario where you want to cache an entire view except for a small bit of it. The more technical term for this technique is probably "cache substitution" as it makes use of the Response.WriteSubstitution method, but I think "Donut Caching" really describes it well - you want to cache everything but the hole in...Full Article.

Building Interactive User Interfaces with Microsoft ASP.NET AJAX: A Look at JSON Serialization
Web applications commonly exchange information between the client (the browser) and the server (the ASP.NET application). In traditional web applications, this communication is usually insinuated when the visitor submits a form. This prompts the browser to re-request the page, sending the values of the form's inputs through the HTTP POST header. The server then renders the page and returns the entire page's markup, which is then redisplayed. AJAX-enabled web applications streamline this...Full Article.
