c# - 无法将 lambda 表达式转换为类型 'CookieAuthenticationOptions'，因为它不是委托(delegate)类型

Question

我正在使用 1.0.1 版本的 asp.net core 并且在我的表单中使用身份验证。

我使用 UseCookieAuthentication 并给出错误

Cannot convert lambda expression to type 'CookieAuthenticationOptions' because it is not a delegate type

在Startup.cs中，配置方法。

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    app.UseApplicationInsightsRequestTelemetry();

    app.UseExceptionHandler("/Home/Error");

    app.UseApplicationInsightsExceptionTelemetry();

    app.UseStaticFiles();
    app.UseSession();

    app.UseCookieAuthentication(options =>
    {
        options.AutomaticAuthenticate = true;
        options.AutomaticChallenge = true;
        options.LoginPath = "/Home/Login";
    });

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=About}/{id?}"
        );
    });
}

您需要传入选项，而不是 lambda:

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AutomaticAuthenticate = true,
    AutomaticChallenge = true,
    LoginPath = "/Home/Login"
});
