'IApplicationBuilder does not includes a definition for UseHealthChecks
As suggested at the tutorial for kubernetes health check I like to implement the health chack at my .NET Core WebApi at class startup.cs at method Configure. But the method .UseHealthCheck() is unknown. I don't know what creates this problem. I guess all usings are there?!?
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseHealthChecks("/health");
app.Run(async (context) =>
{
await context.Response.WriteAsync(
"Navigate to /health to see the health status.");
});
here the using:
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Authorization;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Identity.Client;
using Microsoft.IdentityModel.Logging;
using Microsoft.IdentityModel.Protocols;
using Microsoft.IdentityModel.Protocols.OpenIdConnect;
using Microsoft.IdentityModel.Tokens;
using Newtonsoft.Json;
using Newtonsoft.Json.Serialization;
using System;
using System.Collections.Generic;
using System.Globalization;
using System.IdentityModel.Tokens.Jwt;
using System.Linq;
How to fix this problem?
