添加Microsoft.Identity.Web后ASP.NET Core7 WebAPI的Azure Web App启动失败

在ASP.NET Core 7 WebAPI项目中添加Microsoft.Identity.Web引用（同时使用NSwag）后，部署到Azure Web App无法启动。

配置代码（Program.cs） #

using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.Identity.Web;

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
        .AddMicrosoftIdentityWebApi(options =>
        {
            builder.Configuration.Bind("AzureAdB2C", options);

            options.TokenValidationParameters.NameClaimType = "emails";
        },
   options => { builder.Configuration.Bind("AzureAdB2C", options); });

解决思路 #

• 检查依赖完整性：确认Microsoft.IdentityModel.Logging等Microsoft.Identity.Web的依赖包是否被正确包含在发布包中。查看项目.csproj文件，确保所有必要NuGet包已引用，且默认的CopyLocal配置未被修改。
• 清理重发布：本地执行dotnet clean清除旧构建文件，再执行dotnet publish -c Release重新生成完整发布包，避免缓存依赖缺失问题。
• 验证部署流程：如果使用自动化部署（如CI/CD流水线），检查构建步骤是否正确还原所有NuGet包，且发布的是完整输出目录，无文件遗漏。
• 版本兼容性检查：确认Microsoft.Identity.Web版本与ASP.NET Core 7兼容，尝试升级或降级到稳定兼容版本，排除版本冲突导致的依赖缺失。
• 检查发布目录内容：通过Azure门户的Kudu工具查看Web App的wwwroot目录，确认Microsoft.IdentityModel.Logging.dll是否存在，若缺失可手动复制对应dll到发布目录后重新部署测试。
