I recently upgrading ASP.NET MVC 2 solution from Visual Studio 2008 to Visual Studio 2010 (Ultimate Edition). I found that debugging was very slow. Depending on project size, it took around 30 seconds to initialize and another 5 seconds on each page request in my experience.
Changing default browser used in debugging ASP.NET MVC 2 is a bit tricky in Visual Studio 2010. To use ScottGu’s steps, you will need to add new ASPX page first. But unfortunately if you delete the page then close the application, anytime you rerun the application then the change you did will lost (it backs to use the default browser set in OS).
In my case I have Firefox set as my default browser but I need to use Internet Explorer as default browser for debugging. The trick I do is by doing these:
Open the project properties
Go to Web tab
Set the Start Action to use Start external program and then pass the Internet Explorer executable path and the url as Command line arguments.
Set the Servers’ specific port to the same port set in the url in step 3.
In my previous blog post I wrote that the requirement to enable multi-targeting feature in Visual Studio 2010 is .NET Framework 3.5 SP1 installed in the machine. But why does it not enable the Target Framework dropdown in File -> New -> Project / Web Site dialog of Visual Studio 2010 Express edition? Is multi-targeting not supported in Visual Studio 2010 Express edition?
Visual C# 2010 Express
Visual Web Developer 2010 Express
If you’re a Visual Studio 2010 Express edition user, unfortunately you cannot take advantage of the Target Framework dropdown in the File -> New -> Project / Web Site dialog (as specified in http://msdn.microsoft.com/en-us/library/bb398197.aspx). But it doesn’t mean that multi-targeting is not supported.
By default Visual Studio 2010 Express edition will create the projects with .NET Framework 4 targeted. To change the target framework you can do it from Project Properties (Solution Explorer -> [right click your project] -> Properties)
