Thank you – wavesmash – for posting the instructions for running a website either from a command line or from a right-mouse-click, into Visual Studio.

I walked through his steps and it worked perfectly… exactly what I needed.

1. In Visual Studio, open the Macro IDE (Tools > Macros > Macros IDE…)
2. In MyMacros > References, make sure there is a reference to VsWebSite.Interop and/or VsWebSite.Interop90 (I did both)
3. Right-mouse click on MyMacros and choose Add > Add New Item
4. Choose Code File and give a name “Website” then click Add
5. In the new Website Code File paste the following:

   Public Module Website
   Sub OpenWebsite(Optional ByVal path As String = "")
   If (String.Compare(path, String.Empty) = 0) Then
   MsgBox("Must supply a folder path to the OpenWebsite macro", MsgBoxStyle.OkOnly)
   Else
   Dim webPkg As VsWebSite.VSWebPackage
   webPkg = DTE.GetObject("WebPackage")
   webPkg.OpenWebSite(path, VsWebSite.OpenWebsiteOptions.OpenWebsiteOption_None, False)
   End If
   End Sub
   End Module
   

6. Save and Build

This is ready for running from a command line:

devenv /command “Macros.MyMacros.Website.OpenWebsite C:\MyProjects\MyCompany\CompanySite”

To do this copy the following into a OpenWebsite.reg file and run it.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\OpenVSWeb]
@="Open as Visual Studio Website"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\OpenVSWeb\command]
@="devenv.exe /command \\\"Macros.MyMacros.Website.OpenWebsite %1\\\""

Now you should be able to right click on a folder in Windows Explorer and select “Open as Website”.
