c#-4.0visual studiovisual-studio-2008
I'm pretty aware that Visual Studio 2010 works with C# 4.0. But now I was wandering if I'm able to test C# 4.0 features with Visual Studio 2008.
I did that one time, using C# 3.0 with Visual Studio 2005 hacking the app.config file.
Did anyone have any success using C# 4.0 in VS2008?
I've installed Net Framework 4.0 beta, rebooted, created a new WPF application, chosen Application properties, but the Target Framework can be set only to Net Framework 3.5.
You need to put your directory structure in your project directory. And then click "Show All Files" icon in the top of Solution Explorer toolbox. After that, the added directory will be shown up. You will then need to select this directory, right click, and choose "Include in Project."
See the official GitHub's "Collection of useful .gitignore templates".
The .gitignore for Visual Studio can be found here:

No. You can't use .NET 4.0 with VS2008, and you can't use the C# 4.0 features either - it's exactly the same situation as trying to make VS2005 cope with C# 3.0. The editor, Intellisense etc just don't know about the new features.
One important aspect is that even though it looks like Visual Studio is just using the external
csc.execompiler, it isn't - there's another "in-process" one. That in-process compiler is tied to the version of Visual Studio it comes with, so it only knows about the language features which were available at the time.
