Why are my auto-implemented properties working in ASP.NET 2.0?

I'm using the auto-implemented properties syntax in the C# source files of my ASP.NET Web Application:

public int IdUser { get; set; }
...
this.IdUser = 1;

The Target framework of the project is .NET Framework 2.0. It compile and seems to run properly on a IIS Server with only ASP.NET 2.0 installed. I use Visual Studio 2010 to develop and compile.

I understood this syntax came with .NET 3.
Did I miss a setting somewhere in VS ? Can I expect trouble deploying the website on a IIS/ASP.NET 2.0 server ?

As @Jakub said, it is backwards compatible. For example you can also use implicitly declared variables (var i = 1; //i is int), though they were also only introduced in C#3.0!

You can only run .NET 3.0/3.5 features on a server that has just .NET 2.0 if you're using a web application or a precompiled site, rather than a Visual Studio "web site," since the latter is compiled on the server, where the former are compiled by Visual Studio.

Automatically implemented properties works in .NET 2.0, but you won't be able to compile code in Visual Studio 2005. There is a list of 3.0 features and their compatibility with 2.0

Auto-implemented properties were introduced in .NET 3.0 but are backwards compatible with 2.0. That's why you can run your code on 2.0 framework. Basically, it's just a syntactic sugar and the compiler actually generates a field for you behind the scenes.
