whatsapp-no-contact

A .NET MAUI app to start sending messages to a WhatsApp number without first adding it as a contact

Disclaimer

I created this app for my own entertainment and to learn about .NET MAUI. I am not responsible for any damage or malfunction

About the magic:

await Launcher.OpenAsync($"https://wa.me/{phoneNumber}"); // 😜

Building the Windows app (without installer)

msbuild /restore /t:Publish /p:configuration=Release /p:WindowsAppSDKSelfContained=true /p:Platform="Any CPU" /p:WindowsPackageType=None /p:TargetFramework=net7.0-windows10.0.19041.0 /p:PublishSingleFile=true /p:PublishReadyToRun=false

Building the Android apk

dotnet publish -f net7.0-android -c Release

Don't you want to build it?

then just download it from releases
