This post was written by Rich Lander, who works as a Program Manager on the .NET Framework. He worked on AutoNGEN for Windows 8. This post focuses on how technologies such as Native Image Generator (NGEN), the .NET Framework Optimization Service (mscorsvw), AutoNGEN, and compilation in the cloud have improved the startup performance of .NET apps. (If you want to speed up mscorsvw on your machine, read Wondering why mscorsvw.exe has high CPU usage? You can speed it up.) Use any apps? Pretty much all the time, right? You probably expect most apps, whether they check the weather or a stock price, to start up fast—yo...

Make jQuery UI and Bootstrap 2 work together in MVC template

Xinyang Qiu

In the VS2013 preview MVC5 template, we included Bootstrap and jQuery UI together in the same project. However, some themes of jQuery UI (1.8.24 in the project template) is conflicting with Bootstrap (version 2.3.1 in the project template), especially for button. We have seen at least one such question in our forum. Let’s create a test project first to see the effect. 1. File->New Project, choose Templates->Web->ASP.NET Web Application, select MVC, click Create Project 2. Right click project and choose “Manage NuGet Packages”, go to “Updates” tab, and update “jQuery...

EF/MVC Series updated to EF5/MVC4

Tom Dykstra and I have updated Tom’s popular EF/MVC series to the latest release, that is MVC 4 and EF 5. The biggest change was the addition of code first migrations.  What’s great about the updated 10 part series is you can download the end of each chapter. Suppose you want to get a jump start on Concurrency (Covered in Chapter 7), you can now download the completed chapter 6 and start working on the concurrency tutorial. In addition to bug fixes and new features in MVC and EF, we’ve streamlined the tutorial so you can get through it faster and with less friction. We’ll be monitorin...

This post was written by Rich Lander, a Program Manager on the .NET Framework team. He’s also the one posting as @DotNet on Twitter. Late last month, we released the .NET Framework 4.5.1 Preview. We’re in a spot in our release cycle where we’d appreciate feedback on the pre-release version that we just made available, but we're also starting to think about .NET vNext. A few of us were talking about that, and we thought it would be a good idea to share our approach to feedback. There are two major axes of feedback: time and place. On the time side, we split feedback into real-time and forward-looking. If yo...
