.NET APIs to typeset TeX files

    // Create the format provider using the file system input working directory.
    // Use the project output directory as our custom format file located there.
    using (FormatProvider formatProvider =
        new FormatProvider(new InputFileSystemDirectory(RunExamples.OutputDirectory), "customtex"))
    {
        // Create conversion options for a custom format upon ObjectTeX engine extension.
        TeXOptions options = TeXOptions.ConsoleAppOptions(TeXConfig.ObjectTeX(formatProvider));
        options.JobName = "typeset-with-custom-format";
        // Specify the input working directory if needed.
        // But it is required when the main input has dependencies (e.g. images).
        options.InputWorkingDirectory = new InputFileSystemDirectory(RunExamples.InputDirectory);
        // Specify a file system working directory for the output.
        options.OutputWorkingDirectory = new OutputFileSystemDirectory(RunExamples.OutputDirectory);

        // Run the job.
        new TeXJob(new MemoryStream(Encoding.ASCII.GetBytes(
                "Congratulations! You have successfully typeset this text with your own TeX format!\\end")),
                new XpsDevice(), options).Run();

        // Refine the output.
        options.TerminalOut.Writer.WriteLine();
    }
