Description

Summary

We are still using .NET 6 for our codegen projects and requiring it in our dependency script. We should change that to .NET 8.

Motivation

.NET 6 is no longer supported. and will be a security/compliance issue.

Basic Example

No response

Open Questions

If we update the dependency script to only require .NET 8, then we need to make sure users setting up new projects for RNW versions that used .NET 6 will still work. We'd need to test on clean machines without .NET 6 to see that the Codegen targeting .NET 6 still works if only .NET 8 is installed.

Research direction
Update the dependency script (likely in the repository's scripts or configuration files) to require .NET 8 instead of .NET 6. Ensure that the codegen projects target .NET 8. Test on a clean machine without .NET 6 installed to verify that older RNW versions using .NET 6 still work. Refer to the issue's open questions about backward compatibility and test accordingly.
