16 Nov 2018 ... Steps to remove password from protected PDF programmatically: Create a new C# console application project. Install the Syncfusion. Pdf .WinForms NuGet package as reference to your .NET Framework application from NuGet.org. Include the following namespaces in Program.cs file. The WF team took this concept and incorporated it into WF as well. While the WF XML follows the XAML namespace conventions, filenames containing WF-related XML are customarily named using a .xoml file extension. This approach allows for automated tools to interpret the file as a workflow file instead of as a presentation file. In fact, a tool we ll use in this chapter, the workflow compiler (wfc.exe), demands the .xoml file extension when creating workflows based on XAML. Even though Listing 16-1 isn t a workflow declaration, take a closer look at the XML you see. Notice the XML element name is the same as the supporting .NET WPF class, which in this case is Button. Also worth noting are the attributes the button will have assigned once the XAML file is interpreted: FontSize, Margin, and Foreground. By changing these or adding others, we very easily change the nature of the button. Workflow-based XAML files exhibit the same characteristics. The XML element name represents the activity type, such as CodeActivity or IfElseActivity. And as you might expect, each element can contain properties and their values.
