Feature Request: Install or update to the latest including preview version without providing the version parameter

[ebicoglu]

When you want to update or install a dotnet tool you need to explicitly provide the version which doesn't work in our DevOps environment. Add a new parameter like --preview to update/install the latest preview version.

dotnet tool update -g dotnet-ef --preview
dotnet tool install -g dotnet-ef --preview

Otherwise, our DevOps engineer is struggling to parse the output of the dotnet tool search command. We always run the latest dotnet tool including preview versions. This is a must for our own dotnet global tools like Volo.Abp.Cli

See what we are doing to be able to update to the latest preview version of any dotnet tool package:

$packageName = "dotnet-ef"
$output = dotnet tool search $packageName --prerelease --take 1
$outputString = ("" + $output)
$indexOfVersionLine = $outputString.IndexOf($packageName)
$latestVersion = $outputString.substring($indexOfVersionLine + $packageName.length).trim().split(" ")[0].trim()

Write-Host "Updating "$packageName" to" $latestVersion
dotnet tool update -g $packageName --version $latestVersion
