.net 8 blazor wasm PlatformNotSupportedException

[codegurney]

Using the code from the docs on a Blazor WASM application:
`services.AddSingleton(sp => new FlurlClientCache()
.Add("MyCli", "https://some-api.com"));

public MyService(IFlurlClientCache clients) {
_flurlCli = clients.Get("MyCli");`

causes a PlatformNotSupportedException. Looking at the stack trace, it looks like it is related to UseCookies.

What version of Flurl.Http?

4.0.2

Looking into this a little more, it is a handled exception, but Rider is still breaking when this exception is thrown. Would it be possible to check for WASM before setting the UseCookies property on HttpClientHandler?

[tmenier]

That try/catch is meant to be sort of a future-proof catch-all so Flurl doesn't need to sniff for specific platforms. I'll make a note to look at it, there's some sniffing going on in other areas so this isn't a hard rule. Can you exclude PlatformNotSupportedException from exceptions that Rider breaks on? You can in VS but I'm less familiar with Rider.

And along the lines of future-proofing, if some future version of WASM adds support for UseCookies, this could cause problems. So it's kind of doubtful I'll make a change here, but I will still take a look at it.

Probably. For now, at least in development, I have forked the repo and added...
#if NETCOREAPP if (!OperatingSystem.IsBrowser()) #endif
before the call to
handler.UseCookies = false;
in FlurlClientFactory.cs

[codegurney]

maybe add configuration option to toggle whether or not to use cookies?
