参考这些说明：
我创建了一个 .NET 5.0 隔离函数，最初看起来一切正常。当我运行它时，它只是超时：

它检测到函数并触发触发器，但实际函数未运行（调试器未附加）。
[Function(nameof(MediaUploadProcessorFunction))]
public async Task Run([BlobTrigger(containerName + "/{name}", Connection = "AzureWebJobsStorage")] Stream myBlob, string name, ILogger log)
{
System.Diagnostics.Debugger.Launch();
System.Diagnostics.Debugger.Break();
log.LogInformation($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
}
public MediaUploadProcessorFunction(IEmailService emailService, IMediaRepository mediaRepository, IOptions<ErrorEmailOptions> errorEmailOptions, IOptions<ValuesOptions> valuesOptions, IGroupRepository groupRepository)
{
System.Diagnostics.Debugger.Launch();
System.Diagnostics.Debugger.Break();
_emailService = emailService ?? throw new ArgumentNullException(nameof(emailService));
_mediaRepository = mediaRepository ?? throw new ArgumentNullException(nameof(mediaRepository));
_errorEmailOptions = errorEmailOptions?.Value ?? throw new ArgumentNullException(nameof(errorEmailOptions));
_values = valuesOptions?.Value ?? throw new ArgumentNullException(nameof(valuesOptions));
_groupRepository = groupRepository ?? throw new ArgumentNullException(nameof(groupRepository));
}
然后启动（调试器确实附加了 OK）：
static Task Main(string[] args)
{
System.Diagnostics.Debugger.Launch();
var config = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
.AddEnvironmentVariables()
.Build();
var host = new HostBuilder()
.ConfigureAppConfiguration(configurationBuilder =>
{
configurationBuilder.AddCommandLine(args);
})
.ConfigureFunctionsWorkerDefaults()
.ConfigureServices(services =>
{
services.AddLogging();
services.Configure<ValuesOptions>(config.GetSection("Values"));
services.AddScoped<IMediaRepository, MediaRepository>();
services.Configure<ErrorEmailOptions>(config.GetSection("ErrorEmail"));
services.AddScoped<IEmailService, EmailService>();
services.AddScoped<IGroupRepository, GroupRepository>();
services.AddDbContext<Context>(opts =>
{
var conn = config.GetConnectionString("Context");
opts.UseSqlServer(conn);
});
})
.Build();
return host.RunAsync();
}
有人有什么想法我可以试试吗？

我遇到了类似的问题，并在链接的 github 中发表了评论。感谢您提供资源链接。几个小时后，我看到的是，VSCode 的体验非常棒。在 VS 中是可怕的、有限的和破碎的。我不想想在我们的微服务开发中使用 VSCode，但是通过以下选择 VSCode 的工作很简单，而且很有效。 docs.microsoft.com/en-us/azure/azure-functions/…

几周前我遇到了类似的问题，由于我们与 Function App 共享一些常见项目，我不得不中止将我的 API 应用程序转换到 .net 5。主要原因是将功能转换为孤立的过程。 docs.microsoft.com/en-us/azure/azure-functions/… 此外，您需要 VS 2019 v16.11 来构建生产就绪代码，并且 v16.11 仍处于预览模式，这面临@Corey 提到的问题

为了调试 .net 5 隔离进程，我使用以下 PS：
func start --dotnet-isolated-debug。取自here
