.NET Crash Dump and Live Process Inspection
Analyzing crash dumps can be complicated. Although Visual Studio supports viewing managed crash dumps, you often have to resort to more specialized tools like the SOS debugging extensions or WinDbg. In today’s post, Lee Culver, software developer on the .NET Runtime team, will introduce you to a new managed library that allows you to automate inspection tasks and access even more debugging information. --Immo Today are we excited to announce the beta release of the Microsoft.Diagnostics.Runtime component (called ClrMD for short) through the NuGet Package Manager. ClrMD is a set of advanced APIs for programm...
Please update to the latest version of Web Essentials 2012 after installing VS2012 Update 2
After releasing ASP.NET and Web Tools 2012.2, which is also included in Visual Studio 2012 update 2, we’ve received a few customer feedback about their VS shows an error dialog saying: An exception has been encountered. This may be caused by an extension. You can get more information by examining the file 'C:Users<username>AppDataRoamingMicrosoftVisualStudio12.0ActivityLog.xml'. When looking at ActivityLog.xml, the following error message may show up: System.ComponentModel.Composition.ImportCardinalityMismatchException: Duplicate EditorFormatDefinition exports with identical name attributes exi...
Seeking Feedback on Alternative Formats for ASP.NET MVC and Deployment Content Maps
The ASP.NET content maps are lists of resources that we have reviewed and recommend. The content maps have been popular in their present form, but we’re looking at ways to improve them, such as by publishing more lists but with a narrower focus to each one, by providing more information for each link, and by formatting them differently. Here are links to the existing content maps and three pages that show new approaches we’re considering: We’re calling the new lists “curated views.” Curated in the sense that, although anyo...
Social Engineering
When people in our industry use the term “social engineering” they are usually referring to security attacks. Politicians and lobbyists would mean something entirely different too. But that’s not what I will talk about here. Instead, I’ll talk about the kind of social life we’ve around in our team. Why am I using the term engineering then? Because I strongly believe that building a great team is a conscious effort. Wikipedia defines the term engineering as follows: Engineering is the application of scientific, economic, social, and practical knowledge, in order to design, build, and ...
XDT (XML Document Transform) released on codeplex.com
In Visual Studio 2010 we introduced a simple and straight forward method of transforming web.config during publishing/packaging. This support is called XML Document Transform, aka XDT. It allows you to transform any XML file, not just web.config. To learn more about XDT check out the docs. Since we've released XDT there has been interest in re-using the transformation engine in other scenarios. To enable some of those scenarios we released XDT on NuGet. After that we started working on integrating XDT into NuGet and asked for some feedback from the community. In order to cover all the scenarios for NuGet users ...
The Defrag Tools Channel9 series on managed memory diagnostics
Recently I did a few videos for the popular "Defrag Tools" series on Channel9. They are just talking about pretty basic things about doing managed memory investigations so I'd imagine for most of you it's something you already know. However, you can feel free to suggest things you'd like to see in the comments of these videos (or on this blog for that matter :-)). 2 have aired: https://channel9.msdn.com/Shows/Defrag-Tools/Defrag-Tools-33-CLR-GC-Part-1 https://channel9.msdn.com/Shows/Defrag-Tools/Defrag-Tools-34-CLR-GC-Part-2
Debugging ASP.NET Web API with Route Debugger
Tutorial and Tool written by Troy Dai (Twitter @troy_dai) with assistance from Rick Anderson (Twitter @RickAndMSFT) Search for “asp.net web api routing” on stackoverflow, you’ll find many questions. How exactly does Web API routing work? Why doesn’t my route work? Why is this action not invoked? Often time it is difficult to debug route. To address this issue I wrote this tool named “ASP.NET Web API Route Debugger” trying to make Web API developers’ lives a bit easier. In this article I’ll first introduce stdebugger. Then I’ll introduce how routing works in Web Api. It is followed by three examples of how to...
.NET Memory Allocation Profiling with Visual Studio 2012
This post was written by Stephen Toub, a frequent contributor to the Parallel Programming in .NET blog. He shows us how Visual Studio 2012 and an attention to detail can help you discover unnecessary allocations in your app that can prevent it from achieving higher performance. Visual Studio 2012 has a wealth of valuable functionality, so much so that I periodically hear developers that already use Visual Studio asking for a feature the IDE already has and that they’ve just never discovered. Other times, I hear developers asking about a specific feature, thinking it’s meant for one purpose, not realizing it...
Tutorial Series on Model Binding with ASP.NET Web Forms
I have written a tutorial series that shows how to use model binding with ASP.NET Web Forms. You might be familiar with the model binding concept from ASP.NET MVC, but with ASP.NET 4.5, model binding is now available in Web Forms applications. Model binding makes it very easy to create and maintain data-rich web pages. A lot of the manual steps of correlating elements with data properties are performed automatically. When you use model binding with dynamic data templates, you can quickly add or revise properties in your data model and those properties are correctly ren...
