windows authentication inside remoting
websharperremotingauthentication

This is what I'm trying to do

[Remote]
public static async Task<string> NewDoSomething(string input)
{
    var ctx = WebSharper.Web.Remoting.GetContext();
    var httpContext = ctx.Environment["HttpContext"] as HttpContextBase;
    var user = httpContext.User;

but the user is null

in the same project I've enabled windows authentication, in fact from a web method inside a web form I can do

[WebMethod(EnableSession = true)]
public static async Task<string> TestWebMethod(string input)
{
    IPrincipal currentUser = HttpContext.Current.User;
    string userName = currentUser.Identity.Name;

which works as expected.

What am I missing on WebSharper Remoting side?

.

The C# documentation on remoting shows that there are C# style extension methods that are available with having using WebSharper.Web;.

This is how you can log in then get user name:

// using WebSharper.Web;
[Remote]
public static async Task<string> DoSomething(string input)
{
    var ctx = WebSharper.Web.Remoting.GetContext();
    await ctx.UserSession.LoginUserAsync(input); // extension member
    var username = await ctx.UserSession.GetLoggedInUserAsync(); // extension member
    // after being logged in, this seems to work properly too, giving same result:
    var httpContext = ctx.Environment["HttpContext"] as HttpContextBase;
    var usernameAgain = httpContext.User.Identity.Name;

    return username;
}

Hope this helps, we will be updating the docs for clarity. (You can also post questions/issues and pull request for documentation here)

I suspect that the above is working only for a dot.net Core project but not on the classic Framework.

Notice also that LoginUserAsync seems a Form login, not related to Windows Identity.

@JankoA Thank you very much! It works like a charm!

(fyi I set the debug configuration for windows authentication according to this and I used just the first username you have shown above)

btw for the second option of usernameAgain in my Environment the key was "WebSharper.AspNetCore.HttpContext"

1

var httpContext = ctx.Environment["WebSharper.AspNetCore.HttpContext"] as HttpContext;

but the first option of username was already perfect.

I've also tried

var usernameAsyncAsync = ctx.UserSession.GetLoggedInUser();
var usernameOption = FSharpAsync.RunSynchronously
    (usernameAsyncAsync, 
    timeout: FSharpOption<int>.None, 
    cancellationToken: FSharpOption<CancellationToken>.None);
var userName = usernameOption?.Value;

without success either

By the way GetLoggedInUser should not expose F# Async to C# code because, according to Tomas Petricek

It is generally not recommended to expose F# types such as FSharpAsync in a public interface that will be used by C# clients
