Install one of the following via the Nuget Package Manager from within Visual Studio

• When targeting AnyCPU with Prefer32bit = true then no further action is required. Your application is 32bit and will include the 32bit binaries/resources.
• When targeting AnyCPU please see https://github.com/cefsharp/CefSharp/issues/1714. The MinimalExample demos AnyCPU support and can be used as a reference.

• Review the Post Installation steps in the Readme.txt file that's opened in Visual Studio upon installation.
• Review the Release Notes for the version you just installed, a list of Known Issues for the problems we're currently aware of.
• Check out the API Doc, it's version specific, make sure you pick the correct version.

Add an app.manifest to your exe if you don't already have one, it's required for Windows 10/11 compatibility, GPU Acceleration, HighDPI support and tooltips. See https://learn.microsoft.com/en-us/windows/win32/w8cookbook/windows-version-check#declaring-windows-10-compatibility-with-an-app-manifest

The https://github.com/cefsharp/CefSharp.MinimalExample project contains an example app.manifest file in the root of the WPF/WinForms/OffScreen examples.

<!-- Add a xmlns:wpf="clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf" attribute to your parent control -->
<!-- Create a new instance in code or in `xaml` -->

using CefSharp;
using CefSharp.WinForms;
//Create a new instance in code or add via the designer
var browser = new ChromiumWebBrowser("www.google.com");
parent.Controls.Add(browser);
//Load a different url
browser.LoadUrl("https://github.com");

using CefSharp;
using CefSharp.OffScreen;
//Create a new instance in code

// Add usage statement to access additional functionality
// e.g. EvaluateScriptAsync
using CefSharp;
var response = await browser.EvaluateScriptAsync("1 + 1");
if(response.Success)
{
    var result = response.Result;
