Visual studio .net cannot create or open the application error.

Hi,
I have already have VS 2005 and yesterday I have installed VS 2003 Enterprise Developer. The installation were successfull. But when I open VS 2003 and try to create a new asp.net application its saying "Visual studio .net cannot create or open the application. Web site 'http://localhost/webapplication1' not started on this web server" error.

Any idea what would be the problem ?

Thanks,
Renil.

Visual Studio 2005 has a built in web server environment that lets you develop on.
Visual Studio 2003 does not have this feature. So you must have IIS installed on the machine that you are developing any web project using VS2003.

Do you have IIS installed?
If it is installed, do you have it running?

Yes, I have IIS running on my machine but due to company policy I cannot access its properties.

Hmmm...
Well, you're going to need to use a web server to develop the application.

I'm not sure what to recommend. Maybe talk to someone about setting up your web server so that you can develop the system for them.

Have you tried to create the application on a remote IIS server?
(I think the remote server has to have FrontPage Server Extensions installed to do this)

MS released a free version of their web developer that came with the mini-webserver. "Visual Web Devloper" I think was what it was called.

Also, VS2003 I don't believe supported .NET2.0 so if your system is configured to use those DLLs (as it would be with the install of VS2005) it could be causing issues for VS2003

Yes, I have an old asp.net application(built in VS 2003) in the server that has IIS. Even If I try to open the application its saying the same error message.

But If I try to open the same old application using VS 2005 it works fine.

Thanks.

I have both .net 2.0 and .net1.1
I ran aspnet_regiis -i in the .net1.1 directory to make it current.

Thanks.

That really sounds like .Net2.0 is fighting with other versions of .Net

Although, the solution/project files for 2005 are different then 2003. You will probably have to create a new project and import the files into it if you want to go backwards.

(Why do you need to use 2003 over 2005?)

I have an old production application that built on asp.net/VS 2003 using .net1.1. However my system has VS 2005 installed and If I try to open the old application in VS 2005 its asking me to migrate before even using.

My manager doesn't want to migrate. So they installed VS 2003 on my pc. But now If I try to open the old application using VS 2003 its saying the error message(mentioned earlier). Also I tried creating a new application using VS 2003 but still the same err msg.

Visual Studio 2005 uses .Net Framework 2...whereas Visual Studio 2003 uses .Net Framework 1.1.

It could possibly be a conflict as Plater was saying..
But since you've used the aspnet_regiis -i for the version 1.1 ...the web server should be running it.

I still think that your web server is set up incorrectly. You're going to have to find a way to open the Internet Information Services tool and make sure that your server set up to serve ASP.NET Framework 1.1 applications.....but more importantly you need to check that the server is working properly.

Sometimes you can have a particular version of the .NET Framework installed (say 1.1) and the web server will be set to use the most current version of the .NET Framework (2.0)...despite you using the aspnet_regiis tool...this really causes problems.

You said that you have other applications hosted there.
Are you able to connect and run these applications?
