# Create, read and edit a PowerPoint file in WinUI
Syncfusion Essential PowerPoint is a [.NET Core PowerPoint library](https://www.syncfusion.com/powerpoint-framework/net-core) used to create, read, and edit **PowerPoint** documents programmatically without **Microsoft PowerPoint** or interop dependencies. Using this library, you can **create a PowerPoint document in WinUI**.
**Prerequisites:**
To use the WinUI 3 project templates, install the Windows App SDK extension for Visual Studio. For more details, refer [here](https://docs.microsoft.com/en-us/windows/apps/windows-app-sdk/set-up-your-development-environment).
## WinUI Desktop app
### Create a PowerPoint file in WinUI
1.Create a new C# WinUI Desktop app. Select Blank App, Packaged with WAP (WinUI 3 in Desktop) from the template and click the **Next** button.
![Create the WinUI Desktop app in Visual Studio](Workingwith_WinUI/Create_Desktop_Project.png)
2.Enter the project name and click **Create**.
![Create a project name for your new project](Workingwith_WinUI/Desktop_Configure.png)
3.Set the Target version to Windows 10, version 2004 (build 19041) and the Minimum version to Windows 10, version 1809 (build 17763) and then click **OK**.
![Set the target version](Workingwith_WinUI/Target_Version.png)
4.Install the [Syncfusion.Presentation.Net.Core](https://www.nuget.org/packages/Syncfusion.Presentation.Net.Core/) NuGet package as a reference to your .NET Standard applications from the [NuGet.org](https://www.nuget.org/).
![Install the Presentation .Net Core Nuget](Workingwith_WinUI/Install_Nuget.png)
N> Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, you also have to add "Syncfusion.Licensing" assembly reference and include a license key in your projects. Please refer to this [link](https://help.syncfusion.com/common/essential-studio/licensing/license-key) to know about registering a Syncfusion license key in your application to use our components.
5.Add a new button to the **MainWindow.xaml** as shown below.
{% tabs %}
{% highlight c# %}
<Window
x:Class="CreatePowerPoint.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center">
<Button x:Name="button" Click="CreatePresentation">Create Presentation</Button>
</StackPanel>
</Window>
{% endhighlight %}
{% endtabs %}
6.Include the following namespaces in the **MainWindow.xaml.cs** file.
{% tabs %}
{% highlight c# %}
using Syncfusion.Presentation;
using System.IO;
{% endhighlight %}
{% endtabs %}
7.Add a new action method **CreatePresentation** in MainPage.xaml.cs and include the below code snippet to **create a PowerPoint file**.
{% tabs %}
{% highlight c# %}
//Create a new instance of the PowerPoint Presentation file.
using (IPresentation pptxDoc = Presentation.Create())
{
//Add a new slide to the file and apply background color.
ISlide slide = pptxDoc.Slides.Add(SlideLayoutType.TitleOnly);
//Specify the fill type and fill color for the slide background.
slide.Background.Fill.FillType = FillType.Solid;
slide.Background.Fill.SolidFill.Color = ColorObject.FromArgb(232, 241, 229);
//Add title content to the slide by accessing the title placeholder of the TitleOnly layout-slide.
IShape titleShape = slide.Shapes[0] as IShape;
titleShape.TextBody.AddParagraph("Company History").HorizontalAlignment = HorizontalAlignmentType.Center;
//Add description content to the slide by adding a new TextBox.
IShape descriptionShape = slide.AddTextBox(53.22, 141.73, 874.19, 77.70);
descriptionShape.TextBody.Text = "IMN Solutions PVT LTD is the software company, established in 1987, by George Milton. The company has been listed as the trusted partner for many high-profile organizations since 1988 and got awards for quality products from reputed organizations.";
//Add bullet points to the slide.
IShape bulletPointsShape = slide.AddTextBox(53.22, 270, 437.90, 116.32);
//Add a paragraph for a bullet point.
IParagraph firstPara = bulletPointsShape.TextBody.AddParagraph("The company acquired the MCY corporation for 20 billion dollars and became the top revenue maker for the year 2015.");
//Format how the bullets should be displayed.
firstPara.ListFormat.Type = ListType.Bulleted;
firstPara.LeftIndent = 35;
firstPara.FirstLineIndent = -35;
//Add another paragraph for the next bullet point.
IParagraph secondPara = bulletPointsShape.TextBody.AddParagraph("The company is participating in top open source projects in automation industry.");
//Format how the bullets should be displayed.
secondPara.ListFormat.Type = ListType.Bulleted;
secondPara.LeftIndent = 35;
secondPara.FirstLineIndent = -35;
//Get a picture as stream.
FileStream pictureStream = new FileStream("Image.png", FileMode.Open);
//Add the picture to a slide by specifying its size and position.
slide.Shapes.AddPicture(pictureStream, 499.79, 238.59, 364.54, 192.16);
//Add an auto-shape to the slide.
IShape stampShape = slide.Shapes.AddShape(AutoShapeType.Explosion1, 48.93, 430.71, 104.13, 80.54);
//Format the auto-shape color by setting the fill type and text.
stampShape.Fill.FillType = FillType.None;
stampShape.TextBody.AddParagraph("IMN").HorizontalAlignment = HorizontalAlignmentType.Center;
//Save the PowerPoint Presentation as a stream.
using (FileStream outputStream = new FileStream("Sample.pptx", FileMode.Create))
{
pptxDoc.Save(outputStream);
}
}
{% endhighlight %}
{% endtabs %}
A complete working example of creating a Presentation file in the WinUI Desktop app can be downloaded from this [link](https://www.syncfusion.com/downloads/support/directtrac/general/ze/CreatePowerPoint1714506431).
By executing the program, you will get the **PowerPoint slide** as follows.
