Build samples

[JuandreG]

I am not able to build any of the samples of Sharpnado. I see these errors in visual studio:

This is the version of visual studio I have installed:

If I try to build the MauiSample with VSCode on MacOS, I see errors like this:

error NETSDK1202: The workload 'net6.0-android' is out of support and will not receive security updates in the future.
Please refer to https://aka.ms/maui-support-policy for more information about the support policy.

Obviously the lib and samples should be updated to .NET 8 ...

I can now build the MauiSample on the latest main branch again on Mac OS (after #119 has been merged).

@JuandreG Could you check if this also works on Windows with VS2022 now? (I think it should because the CI build on Windows runs through cleanly, and it includes the MauiSample).

They work now thank you.
