[FLAMESpl]

Hi,

how to confgure CORS on Kestrel that runs Blazor WebAssembly project? (The one that is started as part dotnet run command on client-side project).

All answers I have found on the internet treats about kestrel in ASP.NET backed Blazor (which I am not interested in).

Thanks in advance.

Do you see any error message in the browser console? I.e. what is blocked by CORS.

Can you give a more concrete sample of what you're trying to do?

The "hammer" is

app.UseCors(policy => policy
    .AllowAnyHeader()
    .AllowAnyMethod()
    .AllowCredentials()
    .AllowAnyOrigin());

Maybe #49871 is also relevant for you.

This is code for the server. In my project I do not have a server, just blazor WebAssembly client.
