<p>We have made use of Passolo for a number of years, but it's kind of clunky and overpriced.</p>

<p>It's got to be able to handle winforms and WPF....</p>

<p>Are there any open source alternatives?</p>

Do you need help extracting strings from code?  Tracking down improper use of non-localizable String.Formats in code (i.e. mm/dd/yyyy vs. dd/mm/yyyy)?
