Whenever someone have to work on something in Visual Studio, he have to create a project to easily manage the code and the relative information about it. Visual Studio provides many different types of solutions but you need to choose the best suitable project or solution type. For creating an ASP.NET Project, you need to so following:

1. Open Visual Studio 2005 or 2008, whatever system installed on your PC.
2. In the left hand side of the Start Page, you can see Recent Projects.
3. Below that in the same area, you can find "Create Website" link.
4. IF, by some chance you can not find "Create Website", then go to File->New->Website.
5. There you can find the different solutions related to ASP.NET.
6. Choose the best that fits your needs, I mean if you want to create web services first then choose web services solution.

HINT: Personally I feel, whatever solution you choose, In the location dropdown, always choose HTTP, instead of FTP or File System and specify the path as http://localhost/ProjectName for a simple reason that, if you somehow migrate to different environment like you move from XP to Vista, like I did, I didn't have to worry about changing the settings for the projects and solutions, because, FileSystem uses an ASP.NET Virtual Server to run your project, and that server's PORT Number is configured automatically when you install .Net Framework. So better to choose localhost, do all the programming and then if you have to move to differenr OS, you just need to take copy of your localhost folder, I mean, wwwroot folder under, C:\inetpub.

Moreover, the solutions that you create always saved in your My Document->Visual Studio 2005->Projects, so make sure that you copy that too, before moving to the new OS.

AND ALWAYS, BACK UP THESE 2 FOLDERS.
