ASP.NET API 无法在 Azure 上发布

Question

我正在尝试将 C# API 发布到 azure，我遵循了本文档中的所有步骤，但由于某种原因，当我发布应用程序时，构建会成功，但在执行以下行时会崩溃

Generating swagger file to 'C:\Users\user\Projs\API\bin\Release\netcoreapp3.1\swagger.json'.

打印的唯一错误日志是

Failed to generate swagger file. Error dotnet swagger tofile --serializeasv2 --output "C:\Users\user\Downloads\Projs\API\bin\Release\netcoreapp3.1\swagger.json" "C:\Users\user\Downloads\Projs\API\bin\Release\netcoreapp3.1\API.dll" v1

Unhandled exception. System.IO.FileLoadException: Could not load file or assembly 'System.Runtime, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)

Be sure that the Startup.cs for your application is calling AddSwaggerGen from within ConfigureServices in order to generate swagger file. Visit https://go.microsoft.com/fwlink/?LinkId=2131205&CLCID=0x409 for more information.

这是我的startup.cs

 public void ConfigureServices(IServiceCollection services)
        {

            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc(
                    "v1",
                    new Microsoft.OpenApi.Models.OpenApiInfo { Title = "My API", Version = "v1" });
            });

        }


  public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseHttpsRedirection();

            app.UseRouting();

            app.UseAuthentication();
            app.UseSwagger(c =>
            {
                c.SerializeAsV2 = true;
            });

            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("v1/swagger.json", "MyAPI V1");
            });

            app.UseAuthorization();

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

这是我的.csproj文件

我已经尝试过这些链接中的解决方案，但没有一个有效

Visual Studio 2017 - 无法加载文件或程序集“System.Runtime，版本=4.1.0.0”或其依赖项之一

https://github.com/Azure/azure-functions-vs-build-sdk/issues/160

无法加载文件或程序集“System.Runtime，Version=4.2.1.0，Culture=neutral，PublicKeyToken=b03f5f7f11d50a3a”

有没有办法来解决这个问题？

更新：我尝试了一个解决方案，该解决方案由线程中的用户告知添加绑定重定向，我添加了 aweb.config和 aapp.config并添加了绑定，但它仍然无法发布

更新 2：我找不到解决方案，所以我安装了 .net 5.0 并且它有效

Answer 1

您可以使用最新版本的 Swashbuckle.AspNetCore。我从 GitHub 上的 Swashbuckle 找到了官方解决方法： https://github.com/domaindrivendev/Swashbuckle.AspNetCore/issues/2006

1. 将 global.json 文件添加到您的 Web API 项目

2. 把这个放进去：

   { "sdk": { "version": "3.1.406", "rollForward": "latestPatch" } }
