ASP.NET 核心 api 项目 3.1 发布在 IIS

Question

I am trying to deploy my ASP.NET Core API project in my pc local IIS Server using Web Deploy feature in Visual Studio 2019.

我可以从本地 IIS 服务器成功调用所有 api。

当我发布到远程服务器并调用 api 时，它显示HTTP 错误 500.30 - ANCM In-Process Start Failure错误。

1. 我检查了 applications.json 文件中的无效属性。
2. 我已经从https://dotnet.microsoft.com/download/dotnet-core/3.1安装了 web 托管包

api 来自 web 浏览器的调用

在 ProjectController.cs

---

[HttpGet]
[Route("api/Testing")]
public async Task<IActionResult> GetUserList()
{
    try
    {
        List<PatientName> lstPAtientName = new List<PatientName>();
        lstPAtientName.Add(new PatientName() { PName = "ABC" });
        lstPAtientName.Add(new PatientName() { PName = "XYZ" });

        var dict = new Dictionary<string, object>();
        dict.Add("PatientList", lstPAtientName);

        return Ok(dict);
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

在 Startup.cs 中

---

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers().AddNewtonsoftJson();

        //Configure CORS also to make this API enable for other application
        services.AddCors(option => option.AddPolicy("MyBlogPolicy", builder =>
        {
            builder.AllowAnyOrigin().AllowAnyHeader().AllowAnyMethod();
        
        }));

        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_3_0);
        services.AddScoped<ProjectRepository>();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseHttpsRedirection();

        //Configure CORS also to make this API enable for other application
        app.UseCors("MyBlogPolicy");

        app.UseRouting();

        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
        });
    }

}

有没有加

<AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>

在您的.csproj文件中？
