powershell weirdly encodes ampersands when I try to set the value to an xml attribute
function set-connectionstring {
  param($path, $name, $value)
  $settings = [xml](get-content $path)
  $setting = $settings.configuration.connectionStrings.add | where { $_.name -eq $name }
  $setting.connectionString = "$value"
  $setting.providerName = "System.Data.SqlClient"
  $resolvedPath = resolve-path($path)
  $settings.save($resolvedPath)
}
