I am currently working on our .NET 1.1 to .NET 2.0 conversion project at Vertafore. After recently listening to the Hanselminutes on Msh I figured I would give it a spin.
One of the items we needed to do was run the command line upgrade across all of our projects. At last count we had around 400 so this was a tall order.
Turns out it was only 5 lines of MSH!
Here it is for anyone else that wants it:
$devenv = "C:\program files\Microsoft Visual Studio 8\Common7\IDE\devenv.com"
foreach ($project in get-childitem -include *.csproj -recurse) {
write-host "Upgrading Project: " $project
& $devenv $project /Upgrade
}
