JWT Token based Authentication in Azure AD

i m getting below Error in startup.css while authenticateing token issued by Azure AD

JwtBearerAppBuilderExtensions.UseJwtBearerAuthentication(IA‌​pplicationBuilder, JwtBearerOptions)' is obsolete: 'See go.microsoft.com/fwlink/?linkid=845470';

And my code is 

 app.UseJwtBearerAuthentication(new JwtBearerOptions
            {
                AutomaticAuthenticate = true,
                AutomaticChallenge = true,
                Authority = String.Format(Configuration["AzureAd:AadInstance"], Configuration["AzureAD:Tenant"]),
                Audience = Configuration["AzureAd:Audience"],
            });

Any suggestion please i am new to Azure and web API? Thanks

            arg.Response.Body.Write(Encoding.UTF8.GetBytes(s), 0, s.Length);
            return Task.FromResult(0);
        }

Use the nuget package Microsoft.Owin.Security.ActiveDirectory instead:

app.UseWindowsAzureActiveDirectoryBearerAuthentication(new WindowsAzureActiveDirectoryBearerAuthenticationOptions
{
    TokenValidationParameters = new TokenValidationParameters
    {
        ValidAudience = ConfigurationManager.AppSettings["AzureAd:Audience"]
    },
    Tenant = ConfigurationManager.AppSettings["AzureAd:AADInstance"]
});
