I’m trying to migrate an old asp.net 1.1 application to target the new .net

  • 0

I’m trying to migrate an old asp.net 1.1 application to target the new .net 4.0 framework. There are good guides available on this (https://learn.microsoft.com/en-us/archive/msdn-magazine/2010/september/app-migration-migrate-your-asp-net-1-1-apps-to-visual-studio-2010). However, all approaches start with the assumption that the 1.1 project contains a solution file which one has to open using VS 2010 and go through the conversion wizard.

In my case, the project does not have any solution file, giving me a sort of chicken and egg issue.

Is there a way to add a 1.1 .net soution file with or without VS 2010? Using command line tools? What is so special about a solution file anyway?

    Are the file that you have in a website alreay? Are they located in C:\Inetpub\wwwroot\[SITE_FOLDER]?

    This site might help as well. http://ondotnet.com/pub/a/dotnet/excerpt/vshacks_chap1/index.html?page=4

    Here is a sample solution:

    Microsoft Visual Studio Solution File, Format Version 7.0
Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "C:\...\WebSite1\", "..\..\WebSites\WebSite1", "{A3EF0D1E-ABC0-4A4F-851F-EBC56FDF2C53}"
    ProjectSection(WebsiteProperties) = preProject
        Debug.AspNetCompiler.VirtualPath = "/WebSite1"
        Debug.AspNetCompiler.PhysicalPath = "..\..\WebSites\WebSite1\"
        Debug.AspNetCompiler.TargetPath = "PrecompiledWeb\WebSite1\"
        Debug.AspNetCompiler.Updateable = "true"
        Debug.AspNetCompiler.ForceOverwrite = "true"
        Debug.AspNetCompiler.FixedNames = "false"
        Debug.AspNetCompiler.Debug = "True"
        Release.AspNetCompiler.VirtualPath = "/WebSite1"
        Release.AspNetCompiler.PhysicalPath = "..\..\WebSites\WebSite1\"
        Release.AspNetCompiler.TargetPath = "PrecompiledWeb\WebSite1\"
        Release.AspNetCompiler.Updateable = "true"
        Release.AspNetCompiler.ForceOverwrite = "true"
        Release.AspNetCompiler.FixedNames = "false"
        Release.AspNetCompiler.Debug = "False"
        VWDPort = "2220"
        DefaultWebSiteLanguage = "Visual Basic"
    EndProjectSection
EndProject
Global
    GlobalSection(SolutionConfigurationPlatforms) = preSolution
        Debug|.NET = Debug|.NET
    EndGlobalSection
    GlobalSection(ProjectConfigurationPlatforms) = postSolution
        {A3EF0D1E-ABC0-4A4F-851F-EBC56FDF2C53}.Debug|.NET.ActiveCfg = Debug|.NET
        {A3EF0D1E-ABC0-4A4F-851F-EBC56FDF2C53}.Debug|.NET.Build.0 = Debug|.NET
    EndGlobalSection
    GlobalSection(SolutionProperties) = preSolution
        HideSolutionNode = FALSE
    EndGlobalSection
EndGlobal
