Good morning everyone,

I am running Microsoft Visual Studio 2003 on Win XP Pro. I have .NET framework 2.0. As soon as I open one of my existing ASP.NET applications or try to create a new ASP.NET application, I receive the following error message. I did search google.com for the past few days regarding to this error message and applied several tips from this search but none of them worked. Please advise.

************************************************** *************

Microsoft development Environment

Microsoft development Environment has encountered a problem and needs to close. We are sorry for inconvenience

devenv.exe

Visual studio .NET 2003

An unhandled exception has been caught by the VSW exception filter.

Thanks in advance for any input.

Check your installation it seems that VS setup was not compleeted properly

i missed out one thing do check your iis it may be configured for Asp.Net2.0 and u are using vs2003 try using vs2005

Thanks for your response. I forgot to tell you that when we first installed it (.NET Framework 1.1) and it worked fine. Recently, we upgrade to .NET Framework 2. You asked me to check my installation. Can you please be more specific on how I can check it since I am a newbie. Thanks.

Oh, I just read this message from someone else in the other forum. Let me quote it here:

*************************************
Unfortunately, you can't. VS.NET 2003 targets .NET 1.x; Visual 2005 targets .NET 2.0. You can't mix the two....

You can get yourself a copy of the free Visual Studio versions, like Visual Web Developer Express Edition or C# / VB.NET Express so you can develop against the .NET 2 framework.

************************************

So, does that mean that I need to have Visual Studio 2005 in order to use .NET Framework 2? I currently have VS.NET 2003.

Many thanks in advance for any input you can provide.

Can you make anything else from this:So, yes, to program against .NET 2, use Visual Studio 2005. To program with .NET 1.x you need Visual Studio .NET 2002/ or 2003 (depending on wether .x = .0 or .1)

Cheers,

Imar
