How do I get Visual Studio 2003.NET to use a different version of .NET? RRS feed

  • Question

  • I have VS 2003 installed on a corporate PC.  The add/remove programs tells me that I have installed .Net Framework 1.1, .NET Framework 2.0 SP2, .Net Framework 3.5 SP1 (not sure how I can have 3 but...).  If I look in VS 2003 (help/ about menu) it shows .Net 1.1.4....  I need to use a feature that came with .NET 2.0.  What do I need to do to get Visual Studio to recognize one of the other versions of .NET that I have on the system?  I am remote (2500 miles from my IT shop at work) so I can't get any hands-on help and I don't have access to the install disks.  Is this change easy or impossible in my situation?

  • Hi R.L.O.,

    Thank you for your post.

    As we know, the .NET Framework has two main components: the common language runtime (CLR) and the .NET Framework class library. CLR is the foundation of the .NET Framework. .NET Framework 3.5 uses CLR version 2.0 and so does .NET Framework 2.0 or 3.0, while .NET framework 1.1 uses v1.1. Thus, there're many changes between .NET 1.1 and .NET 2.0.

    Visual Studio 2003 targets .NET Framework 1.1 as default. It does not have access to various new project and item templates and tools that support .NET Framework 2.0. If developers want to use some new features come along with .NET 2.0 which would be necessary in Visual Studio 2005 or Visual Studio 2008 because the two versions compile the new features.
    In addition, VS 2008 support multi-target: which means that we can choose the target Framework from 2.0 to 3.5.

    Thus, if you want to develop .NET 1.1 application, it would be better to use Visual Studio. For .NET 2.0, 3.0 or 3.5 application development, I think that Visual Studio 2008 could be the better choice.

    Hope this helps! If you have any concern, please feel free to let me know.
