2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.
   
   

3. Include the following namespaces in Program.cs file
   C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO; 

4. Use the following code example to add a checkbox content control with a tick mark in a Word document.
   C#

using (WordDocument document = new WordDocument())
{
   // Add one section and one paragraph to the document.
   document.EnsureMinimal();

   // Create a CheckBoxState for the checked state, using a tick symbol in the Wingdings font
   CheckBoxState tickState = new CheckBoxState
   {
       Font = "Wingdings",
       Value = "\uF0FE" // Unicode for the tick symbol (✓) in Wingdings
   };
   // Create a CheckBoxState for the unchecked state, using an empty box symbol in the Wingdings font
   CheckBoxState unTickState = new CheckBoxState
   {
       Font = "Wingdings",
       Value = "\uF0A8" // Unicode for the empty box symbol in Wingdings
   };

   // Gets the last paragraph.
   WParagraph paragraph = document.LastParagraph;
   // Add text to the paragraph.
   paragraph.AppendText("Gender:\tFemale ");
   // Append checkbox content control to the paragraph for the "checked" option.
   IInlineContentControl checkBox = paragraph.AppendInlineContentControl(ContentControlType.CheckBox);
   // Set the checked state of the checkbox content control to display the tick symbol when selected
   checkBox.ContentControlProperties.CheckedState = tickState;
   // Set the unchecked state of the checkbox content control to display an empty box when not selected
   checkBox.ContentControlProperties.UncheckedState = unTickState;
   // Set the initial state of the "Female" checkbox to checked
   checkBox.ContentControlProperties.IsChecked = true;

   // Add text to the paragraph.
   paragraph.AppendText("\tMale ");
   // Append checkbox content control to the paragraph for the "unchecked" option.
   checkBox = paragraph.AppendInlineContentControl(ContentControlType.CheckBox);
   // Set the checked and unchecked states.
   checkBox.ContentControlProperties.CheckedState = tickState;
   checkBox.ContentControlProperties.UncheckedState = unTickState;
   // Set the initial state of the "Male" checkbox to unchecked
   checkBox.ContentControlProperties.IsChecked = false;

   // Save the document.
   using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.OpenOrCreate, FileAccess.ReadWrite))
   {
       document.Save(outputStream, FormatType.Docx);
