PowerShell Script to rename .NET projects

Renaming a .NET project is tedius. You have to rename the files and folders. You also have to replace the content in the files, such as namespace, or path in .sln files. Here's a PowerShell script that renames files and folders and replaces content in files:

$ErrorActionPreference = "Stop"

$rootFolder = Resolve-Path -Path "."
$oldName = "Sample.Foo"
$newName = "Sample.Bar"

# Rename files and folders
foreach ($item in Get-ChildItem -LiteralPath $rootFolder -Recurse | Sort-Object -Property FullName -Descending) {
    $itemNewName = $item.Name.Replace($oldName, $newName)
    if ($item.Name -ne $itemNewName) {
        Rename-Item -LiteralPath $item.FullName -NewName $itemNewName
    }
}

# Replace content in files
foreach ($item in Get-ChildItem -LiteralPath $rootFolder -Recurse -Include "*.cmd", "*.cs", "*.csproj", "*.json", "*.md", "*.proj", "*.props", "*.ps1", "*.sln", "*.slnx", "*.targets", "*.txt", "*.vb", "*.vbproj", "*.xaml", "*.xml", "*.xproj", "*.yml", "*.yaml") {
    $content = Get-Content -LiteralPath $item.FullName
    if ($content) {
        $newContent = $content.Replace($oldName, $newName)
        Set-Content -LiteralPath $item.FullName -Value $newContent
    }
}
