  3. In the New Project dialog box, choose either "Visual C#" or "Visual Basic" then "Workflow" in the Projects Type List, and choose "Sequential Workflow Console Application" in the Templates List.
  4. Type the project name as "WfLoadSave" in the Project Name field, and then choose OK. If desired, type a new location for your project or select a directory using the Browse button, and then choose OK.
  5. In the "Solution Explorer" window, right-click on the "References" folder, and select "Add Reference..." from the context menu. In the "Add Reference..." dialog box, select the ".NET" tab, browse to the "<LEADTOOLS_INSTALLDIR>\Bin\DotNet\Win32 folder, and select the following DLLs:
    • Leadtools.Workflow.Raster.dll
    • Leadtools.Workflow.ImageProcessing.dll
  6. Click Select and then click OK to add the above DLLs to the application.
  7. Set the output folder of the project .exe to where LEADTOOLS 17.5 .Net DLLs are installed. For example: "<LEADTOOLS_INSTALLDIR>\Bin\Dotnet\Win32".
