Over the past few days, some users have reported debugging Visual Studio 2012.
As a .NET developer, I spend a lot of time hitting F5, hitting breakpoints, and trying to figure out why the code I just came up with isn’t working. When the tech web went viral in Microsoft’s Visual Fashion Studio offering, the first thing I wanted to know was what improved features were added and what improvements were made to the overall debugging process. I’ve found that the many changes to the debugging methods in Visual Studio 2012 help developers identify issues faster and provide smoother debugging overall. In this article, I’ll cover five debugging features that everyone should know about and that can be included in Visual Studio 2012 development.
Some design ideas require the use of browser diagnostic tools to access the page’s DOM and troubleshoot various issues. You now have a copy of these changes on the back of your IDE. Page Inspector, a new feature in Visual Studio 2012, makes this process much easier. Page Inspector is a functional web development tool likeA browser-based interface that runs entirely within Visual Studio. This means, again, that you can choose Page To Inspector as your default browser for IE, Firefox, or Chrome. When working in debug mode, you should definitely use the Page Inspector to navigate CSS rules, edit text, and make live changes to the DOM unless you need to switch between the browser and Visual Studio (see Figure 1)
Just imagine one thing: Page Inspector makes it easy for an agency to debug and switch apps
A useful aspect of this page inspector is the inspect mode, and you can also toggle it by selecting Inspect, as shown in the two frames below.
In inspect mode, when you hover over any section of HTML, the page inspector highlights the markup that is causing this issue. This makes it easier to spot bad markup, make changes, and thus update the page without running the Page Inspector.
Continue editingChecking is a longstanding debugging feature in Visual Studio that certainly allows a developer to edit code while debugging without having to restart the program. A frustrating feature of Edit and Continue in Visual Studio 2010, in conjunction with previous versions, was versions that did not allow the developer to maintain code fixes in methods containing unknown methods (eg, lambda expressions, LINQ queries). This is now possible in Visual 2012 Studio. It’s important to note that Modify and Continue probably won’t let you change pins in the actual lambda terms or LINQ query, but anything new that includes an anonymous method is now generally legal (see Figure 3). p>
Image color=”midnightBlack” 3: The highlighted LINQ query is still uneditable, but everything else in the method can be changed to “Edit and Continue” immediately.
In earlier versions of Visual Studio, multiple (threaded) developer debug applications had to perform their debugging operations one binding at a time. This meant that every time you needed to look for another stream, you opened up the wind your flow pane and double-clicked new message for context switch . For applications with many of these threads, this can become tedious. Visual Studio 2012 introduces a creative debug window called Parallel Watch. This window allows you to define a new large expression to simultaneously evaluate and observe the nature of the results for each stream.

This is a trivial game system application that creates streams where everyone writes integers up to 10. Let’s say we prefer to know what is currently valued at the maximum. the variable “num” in each thread, which is bound to the last thread on startup. Synchronized clock displays everything at once:

Experts can now easily see the value of “number” in any stream without having to constantly change the stream’s label. In this example, we are interested inOnly the value of one variable, but you can evaluate more complex expressions.
One of the limitations of Page the Inspector is that it can only be used occasionally for browser-launched applications, which means it doesn’t train if you need to debug great app for the Windows Store. Luckily, Studio 2012 offers two new gear windows that can help: (1) DOM Explorer and (2) JavaScript Console.
(Note: DOM explorer and JavaScript console can also be used if you plan on debugging the browser as well as debugging Windows Store apps, but usually only the Page Inspector is available. in terms of browser debugging.)
