Question

I’ve checked out a branch of C# code from source control. It contains maybe 50 projects in various folders. There’s no existing .sln file to be found.

I intended to create a blank solution to add existing solutions. The UI only lets me do this one project at a time.

Is there something I’m missing? I’d like to specify a list of *.csproj files and somehow come up with a .sln file that contains all the projects.

Answer 1

A PowerShell implementation that recursively scans the script directory for .csproj files and adds them to a (generated) All.sln:

$scriptDirectory = (Get-Item $MyInvocation.MyCommand.Path).Directory.FullName
$dteObj = [System.Activator]::CreateInstance([System.Type]::GetTypeFromProgId("VisualStudio.DTE.12.0"))

$slnDir = ".\"
$slnName = "All"

$dteObj.Solution.Create($scriptDirectory, $slnName)
(ls . -Recurse *.csproj) | % { $dteObj.Solution.AddFromFile($_.FullName, $false) }

$dteObj.Solution.SaveAs( (Join-Path $scriptDirectory 'All.sln') ) 

$dteObj.Quit()
