        static async Task MainAsync()
            var prizmDocServer = new PrizmDocServerClient("https://api.accusoft.com", "YOUR_API_KEY");

            // OCR an image-only PDF, creating a new PDF:
            ConversionResult result = await prizmDocServer.OcrToPdfAsync("scanned.pdf");
            await result.RemoteWorkFile.SaveAsync("output.pdf");

            // OCR a collection of JPEG scans, creating a single output PDF:
            ConversionResult result = await prizmDocServer.OcrToPdfAsync(new ConversionSourceDocument[]
            await result.RemoteWorkFile.SaveAsync("output.pdf");
