ProxyKit VS zerosharp

Worth noting that YARP (or as someone has eloquently described it as PRAY) here was another Microsoft project which basically killed a previous open source project which did the same thing:

https://github.com/proxykit/ProxyKit

This actually feels like one of the instances that PeachPie with a combination of ProxyKit or YARP would be handy.

You could setup a proxy with ProxyKit in you WebHost. Your blazor app will send requests to, say http://webhost:5000/api/endpoint. The host will then forward the request to http://webapi:3000/endpoint (or whatever). You'll have to setup some kind of JWT authentication where the WebHost generates a JWT on login and saves it in the cookie. Good thing here is, the cookie really only contains some id the server uses to look up the actual contents of the cookie. Only the cookie gets returned to the browser (blazor app). On each api request, the webhost will fetch the token out of the server-side cookie and append it to the Authorization header. The webapi will validate the token and return the response that will be proxied back to your front-end.

Not sure why you would want to use C# without it’s open source framework but here it is: https://github.com/MichalStrehovsky/zerosharp

C# without .NET is like C without glibc. Possible but you'll need another core library. For C# that would be something like Mono or ZeroSharp.

NativeAOT definetely can do bare metal, here's an example of a very basic EFI boot application:

Here's one example repo that uses that feature if you are interested: https://github.com/MichalStrehovsky/zerosharp

This is false. You can even make UEFI application in C#

check https://github.com/MichalStrehovsky/zerosharp/tree/master/efi-no-runtime

Kind of. There's https://github.com/MichalStrehovsky/zerosharp demonstrating some bare metal capabilities.
