尝试将我的应用服务从VS 2022部署到Azure时遇到问题。每次我都收到此错误：

我的目标框架是.NET 6，Swashbuckle.AspNetCore包更新到最新版本，应用服务发布成功，但尝试更新API时弹出错误。
在我的项目版本中，没有Startup.cs，只有Program.cs，我实现Swagger生成的方式是：

builder.Services.AddSwaggerGen();
var app = builder.Build();
app.UseSwagger();
app.UseSwaggerUI();

我浏览过类似的帖子，基于它们，我可以补充说，我也没有获取任何环境变量。
我也试过像这样使用UseSwaggerUI()，但还是得到了同样的错误：

app.UseSwaggerUI(options =>
{
    options.SwaggerEndpoint("/swagger/v1/swagger.json", "v1");
    options.RoutePrefix = string.Empty;
});

奇怪的是，部署对我的同事很有效，对我也很有效，直到上周，当Program.cs中的任何内容都没有更改时，部署停止了。
我的程序.cs：

var builder = WebApplication.CreateBuilder(args);
var azureKeyVaultUrl = builder.Configuration[AppConfigurationConst.AzureKeyVaultUrl];
var logAnalyticsWorkspaceId = AzureKeyVaultHelper.GetAzureKeyVault(azureKeyVaultUrl, AppConfigurationConst.LogAnalyticsWorkspaceId);
var logAnaliticsAuthenticationId = AzureKeyVaultHelper.GetAzureKeyVault(azureKeyVaultUrl, AppConfigurationConst.LogAnaliticsAuthenticationId);
var CrmConnectionString = AzureKeyVaultHelper.GetAzureKeyVault(azureKeyVaultUrl, AppConfigurationConst.OneCrmConnectionString);

var logger = new LoggerConfiguration()
               .WriteTo.AzureAnalytics(logAnalyticsWorkspaceId, logAnaliticsAuthenticationId)
               .Enrich.FromLogContext()
               .CreateLogger();

var serviceClient = new ServiceClient(CrmConnectionString);

builder.Logging.AddSerilog(logger);

logger.Information("Start ALGOI App Service");

builder.Services.AddControllers().AddNewtonsoftJson();

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

builder.Services.AddSingleton<IAuthenticationService, AuthenticationService>();
builder.Services.AddSingleton<IWebClientService, WebClientService>();

builder.Services.AddScoped<ICreateSessionService, CreateSessionService>();
builder.Services.AddScoped<ICreateFolderService, CreateFolderService>();
builder.Services.AddScoped<IDeleteFolderService, DeleteFolderService>();

builder.Services.AddScoped<IVerifyFolderService, VerifyFolderService>();
builder.Services.AddScoped<IUndoFolderService, UndoFolderService>();

builder.Services.AddSingleton(serviceClient);
builder.Services.AddApplicationInsightsTelemetry(builder.Configuration["APPLICATIONINSIGHTS_CONNECTION_STRING"]);

var app = builder.Build();

if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.UseAuthorization();

app.MapControllers();

app.Run();

以及我的.csproj：

编辑：我发现错误的原因是这些行：

var azureKeyVaultUrl = builder.Configuration[AppConfigurationConst.AzureKeyVaultUrl];
var logAnalyticsWorkspaceId = AzureKeyVaultHelper.GetAzureKeyVault(azureKeyVaultUrl, AppConfigurationConst.LogAnalyticsWorkspaceId);
var logAnaliticsAuthenticationId = AzureKeyVaultHelper.GetAzureKeyVault(azureKeyVaultUrl, AppConfigurationConst.LogAnaliticsAuthenticationId);
var CrmConnectionString = AzureKeyVaultHelper.GetAzureKeyVault(azureKeyVaultUrl, AppConfigurationConst.OneCrmConnectionString);

我已经将它们更改为直接从配置而不是keyvault获取值：

var azureKeyVaultUrl = builder.Configuration.GetValue<string>(AppConfigurationConst.AzureKeyVaultUrl);
var logAnalyticsWorkspaceId = builder.Configuration.GetValue<string>(AppConfigurationConst.LogAnalyticsWorkspaceId);
var logAnaliticsAuthenticationId = builder.Configuration.GetValue<string>(AppConfigurationConst.LogAnaliticsAuthenticationId);
var CrmConnectionString = builder.Configuration.GetValue<string>(AppConfigurationConst.OneCrmConnectionString);

在本地运行时，它正确地获取值并将其赋值给变量。但在部署时，它似乎遇到了一个问题。在var serviceClient = new ServiceClient(CrmConnectionString);行中，当我将变量更改为静态字符串时，它工作正常，但在使用变量时，弹出startup.cs错误（仅在部署时）。初始化日志记录器也是如此，它使用日志分析值。同样，本地运行没有问题，只是部署崩溃。

我已经创建了一个示例ASP.NET Core 6.0 Web API，并且能够将应用程序部署到Azure App Service，没有任何错误。
通常，当代码中存在任何错误或配置问题时，就会发生此类错误。
在我的项目版本中，没有Startup.cs，只有Program.cs

.Net6 Core文件夹结构：

是的，我们需要在Program.cs本身中Configure与Swagger相关的代码。
检查以下步骤，并确保您按照相同的步骤进行部署，没有任何问题。

选择ASP.NET Core Web API模板。
选择Enable openAPI support .

我的.csproj文件：

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Swashbuckle.AspNetCore" Version="6.2.3" />
  </ItemGroup>
</Project>

我的Program.cs文件：

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddControllers();
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();

var app = builder.Build();
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}
else
{
    app.UseSwagger();
    app.UseSwaggerUI(options =>
    {
        options.SwaggerEndpoint("/swagger/v1/swagger.json", "v1");
        options.RoutePrefix = string.Empty;
    });
}

app.UseHttpsRedirection();
app.UseAuthorization();
app.MapControllers();
app.Run();
