Description

Azure Function Core Tools incorrectly default to .NET 6 (unsupported since November 12, 2024) when creating an in-process Function. It should use .NET 8 (the current LTS) instead when --target-framework is not specified.

Steps to reproduce

# This incorrectly creates a .NET 6 in-process Function, it should default to .NET 8 (that's the current LTS)
func init MyProjFolder --worker-runtime dotnet

Forcing the Function App to use .NET 8:

# This creates a .NET 8 in-process Function
func init MyProjFolder --worker-runtime dotnet --target-framework net8.0

Thanks for flagging this. We have precedence from changing the default version in the isolated worker model. Updating the default for the in-process model would help with consistency and prevent folks from inadvertently landing on an unsupported version.

For whoever ends up picking this item up, this likely would be a change to the following line, with corresponding test updates:

azure-functions-core-tools/src/Azure.Functions.Cli/Actions/LocalActions/InitAction.cs

Line 64 in 208362c

private const string DefaultInProcTargetFramework = Common.TargetFramework.net6;
