将.net6升级到.net8后出现运行时错误

Question

将.NET 6 Function App项目升级到.NET 8后，构建成功。但是，控制台中存在运行时错误。我已成功更新所有相关的 NuGet 包和依赖项。这里我附上了升级前后的.csproj文件，以及Startup.cs文件。

这是控制台错误。

这是升级前的.csproj 文件。

正如我在评论中提到的，您必须添加应用程序设置 "FUNCTIONS_INPROC_NET8_ENABLED": "1" 才能解决错误

Could not load file or assembly 'Microsoft.AspNetCore.Routing

。

更新了您的 local.setting.json 如下：

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_INPROC_NET8_ENABLED": "1",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "Environment": "LOCAL",
    "GeneralTopicName": "sbt-general",
    "UserAccountCrudEventsSubscriptionName": "useraccount-crud",
    "ApplicationInsightsInstrumentationKey": "",
    "KeyVaultDomain": "",
    "ServiceBusConnectionString": "connectionstring",
    "SystemHostUrl": "http://localhost:4200/#",
    "AIHostUrl": "http://localhost:7075/#",
    "SystemDefaultLanguage": "en-AU"
  },
  "PEMS-UserAccount-DbConnection": {
    "DatabaseId": "pemsdb",
    "DefaultCollectionId": "useraccount_default"
  },
  "ServiceBusOperationTimeoutInSeconds": 60
}

控制台输出：

        Function1: serviceBusTrigger
