I am trying to use Auto-implemented properties in VS2005. I have .NET 3.0 framework loaded on my machine, but Visual Studio is still compiling with .NET 2.0. How do I tell it to use .NET 3.0?

I think that you mean C# 3.0, not .NET 3.0, since auto-implemented properties were added in C# 3.0 (which shipped with .NET 3.5). .NET 3.0 was the WPF/WCF/WF release. – Andy Apr 03 '09 at 22:05

Unfortunately, I don't think it is possible to do this, since that is a feature of the C# compiler. Visual Studio 2005 is hard-coded to use the C# 2.0 compiler. You need to upgrade to Visual Studio 2008 to use the new C# 3.0 features.

.NET 3.0 was released before vs2008, how were we to use the new framework when it was released? – Brettski Apr 03 '09 at 22:08

At the time, there was a WPF CTP, and a WCF CTP that added the ability to write .NET 3.0 apps to VS2005. Since VS2008 supports them by default, those CTPs are no longer supported. – Andy Apr 03 '09 at 23:16

Autogenerated properties require C#3.0 which isn't available in VS2005. You need to use VS2008 to get the autogenerated property syntax.

Go to your project properties. Under the application tab you can change your Target Framework

You can only change the target framework in VS2008 (and later, I presume). The OP is using VS2005. – Andy Apr 03 '09 at 22:07

This is an ASP.NET project, I don't see the option you indicated above. – Brettski Apr 03 '09 at 22:07

Wow, I'm not sure how I missed that. It's been a long week - my apologies – Jason Irwin Apr 03 '09 at 22:17
