Potential improvement

I am not a professional C# programmer, but I've tried my best.

Hi, thanks for this contribution!

Sadly, currently the repo CI is in a bad state as the .NET SDK repo needs some love.
I have opened #34 to schedule work to get the CI green. I would like to wait until the CI is green so we can work on features reliably, hence, please have a bit of patience with this PR.

Thanks for your contribution and sorry for the delay, I was on vacation.

As @viccuad said the current status of C# policies is not good.

There's some maintenance work we have to do that has been postponed because, so far, nobody from the community has shown interest about C# policies.

This is the work to be done:

• wapc-guest-dotnet: update to .NET 8, replace the now discontinued dotnet-wasi-sdk
• this repository: update to .NET 8, consume latest version of wapc-guest-dotnet

What are you plans with regard to C# usage? Would you like to help us with this work (we are not top notch C# developers 🥲)

What are you plans with regard to C# usage?

We're a C# shop here, and looking to replace OPA with Kubewarden, so we rewrote all our policies in C#. It's much much easier than Rego, so our general idea was "C# policies or bust". We managed to get all our policies written and working under the current C# SDK, so it does at least work. But I do agree there's a chance for improvement.

I can try to help, I'm not a C# developer (or even a developer) myself, but I'm sure something is better than nothing :)
