In this step you will create a new project and add a reference to the C1.UWP.Excel assembly.

1. Create a new Windows Store project. When the project opens, double-click the MainPage.xaml file to open it.
2. Right-click References in the Solution Explorer and select Add Reference from the list.
3. Browse to find C1.UWP.Excel.dll.
4. Click OK to add the assembly reference to your application.
5. In XAML View, place your cursor between the <Grid> </Grid> tags.
6. Add two standard Button controls and one standard TextBox control to the page.
7.  Edit the markup for the first button so that it resembles the following:

   Markup	Copy Code
   <Button x:Name="HelloButton" Content="Click Hello" />

8. Edit the markup for the second button so that it resembles the following:

   Markup	Copy Code
   <Button x:Name="SaveButton" Content="Save" />

9. Edit the markup for the TextBox control so that it resembles the following:

   Markup	Copy Code
   <TextBox Name="_tbContent" Text="Empty" IsReadOnly="True" AcceptsReturn="True" FontFamily="Courier New" Background="White" Margin="465,10,242,722" />

10. Create  an event named HelloButton_Click for HelloButton and switch to the code view of MainPage.xaml. This will also add a HelloButton_Click event to the code.
11. Switch back to Design View and double-click the SaveButton to add a SaveButton_Click event to the code.
12. Add the using (C#) statement to the code at the top of the form so you can use all names within the C1.Xaml.Excel namespace.

    C#	Copy Code
    using C1.Xaml.Excel; using Windows.UI;

Now you can add some content to a C1XLBook.
