These are some samples to demonstrate the usage of WinUI 3

Ensure that your development computer has Windows 10, version 1803 (build 17134), or a later version installed. WinUI 3 for desktop apps requires 1803 or a later OS version.

Install Visual Studio 2019, version 16.7 Preview 1. You can download this from Visual Studio Preview.

You must include the following workloads when installing the Visual Studio Preview:

• .NET Desktop Development
• Universal Windows Platform development

To build C++ apps you must also include the following workloads:

• Desktop development with C++
• The C++ (v142) Universal Windows Platform tools optional component for the Universal Windows Platform workload

Install both x64 and x86 versions of .NET 5 Preview 4:

• x64: https://aka.ms/dotnet/net5/preview4/Sdk/dotnet-sdk-win-x64.exe
• x86: https://aka.ms/dotnet/net5/preview4/Sdk/dotnet-sdk-win-x86.exe
