运行 ASP.NET Core 集成测试时出现下面的错误：
System.InvalidOperationException : No method 'public static IWebHostBuilder CreateWebHostBuilder(string[] args)' found on 'AutoGeneratedProgram'. Alternatively, WebApplicationFactory`1 can be extended and 'protected virtual IWebHostBuilder CreateWebHostBuilder()' can be overridden to provide your own IWebHostBuilder instance. Stack Trace: at Microsoft.AspNetCore.Mvc.Testing.WebApplicationFactory`1.CreateWebHostBuilder()
请问如何解决？
