Azure App Service is a service used to create and deploy scalable, mission-critical web apps.
Hi @ChristophWille-5880
It looks like you're seeking an updated Microsoft.Web.Deployment NuGet package to help move your .NET Framework app to .NET 8 for Azure Functions.
The current package targets .NET Framework 4.5 and might not work fully with your .NET 8 Azure Functions project. It's understandable to want the same reliability as before.
If the NuGet package isn’t updated, you could use built-in Azure deployment methods like SCM Zip deploy or Azure DevOps. Since you’ve had success with zip deployment, that could be a good interim solution.
You might consider requesting Microsoft to update the package for .NET 8 or open-source it if that fits their plans.
Review .NET 8 GA available on App Service for support details.
