Convert a project of VS.NET 2003 back to VS.NET 2002

Between VS.NET 2003  and VS.NET 2002 has i different format (actually some new tags and version identifiers.)

so we can't open those projects/solutions that created/modified by VS.NET 2003 with VS.NET 2002.

but we can make VS. net 2003 back to vs. net 2002 by modifying the solution files and the project files .

Step 1: Modify the Solution Files
  Change the first line of the solution files from “Microsoft Visual Studio Solution File, Format Version 8.00” to “Microsoft Visual Studio Solution File, Format Version 7.00”

 Step 2: Modify the Project Files
A. For C Sharp:

            ProjectType = "Local"
        ProductVersion = "7.10.3707"
        SchemaVersion = "2.0"
        ProjectGuid = "{20502969-7071-4065-BDB5-09EDB3C31E3C}"
>

Change the above lines to the following lines:

            ProjectType = "Local"
        ProductVersion = "7.0.9466"
        SchemaVersion = "1.0"
        ProjectGuid = "{20502969-7071-4065-BDB5-09EDB3C31E3C}"
>

Beaware of the ProjectGuid, it should be same with actual ones.

B. For Visual Basic.NET
            ProjectType = "Local"
        ProductVersion = "7.10.3707"
        SchemaVersion = "2.0"
        ProjectGuid = "{6E100C4A-A121-4C1F-83BF-BE639BC59CF1}"
>

Change the above lines to the following lines:

           ProjectType = "Local"
        ProductVersion = "7.0.9466"
        SchemaVersion = "1.0"
        ProjectGuid = "{6E100C4A-A121-4C1F-83BF-BE639BC59CF1}"
