PowerShell script to find and open solution (.sln) files

Finding and opening Visual Studio solutions in multiple projects and branches can be painful at times. This simple script may help:

param([int]$OpenId)

$it = 0
$sln = dir -Filter *.sln -Recurse | 
    sort FullName |
    % { New-Object psobject -Property @{ Id = ++$it; Name = $_.Name; FullName = resolve-path -relative $_.FullName } }

if($OpenId)
{
    if($OpenId -lt 0 -or $OpenId -gt $sln.length)
    {
        throw "Invalid Id."
    }

    & $sln[$OpenId - 1].FullName
}
else
{
    $sln
}
