asp.net - Visual Studio 2008 Development Server uses C# 2.0 compiler -


I have an exam website with VS 2008 which just uses code behind files, such as Foo.Aspx . In this way, the web server compiles them on the fly. The problem I am running is that I can not use any of the C # 3.0 features if I do:

var x = 1;

or

public square fu {public int x {get; Set;}}

or

Foo x = new Foo () {x = 5};

Then the VS will work fine (everything is highlighted and intelligently), but when I run the site, it just throws the compiler errors.

Is there a way, or do you have to compile the DLL to target the 3.0 runtime? If it is, then it is lame ..

Mike

There is only 2.0 runtime, There is no 3.0 or 3.5 runtime. They are just additional library and I believe that a different C # compiler

See

Are you sure that the machine you are on is 3.0 or 3.5 installed? If it is local on the same machine that you have Studio 2008, then it should

Because you need C # 3 compiler and BCL, but the CLR version will still be 2.0.

Therefore, please provide new versions installed on the machine running on IIS. .

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
