如何使用 .NET Core 3.x 與 Azure Function 應用程序 Z531B84AD41B2A7501DA83ACF367 運行時？

Question

我使用模板中的以下資源創建了一個新的 Function 應用程序：

    {
      "apiVersion": "2015-08-01",
      "type": "Microsoft.Web/sites",
      "name": "[parameters('caAppName')]",
      "location": "[parameters('location')]",
      "kind": "functionapp",
      "dependsOn": [
        "[resourceId('Microsoft.Web/serverfarms', parameters('hostingPlanName'))]",
        "[resourceId('Microsoft.Storage/storageAccounts', variables('storageAccountName'))]"
      ],
      "identity": {
        "type": "SystemAssigned"
      },
      "properties": {
        "serverFarmId": "[resourceId('Microsoft.Web/serverfarms', parameters('hostingPlanName'))]",
        "siteConfig": {
          "appSettings": [
            {
              "name": "AzureWebJobsStorage",
              "value": "[concat('DefaultEndpointsProtocol=https;AccountName=', variables('storageAccountName'), ';AccountKey=', listKeys(variables('storageAccountid'),'2015-05-01-preview').key1)]"
            },
            {
              "name": "WEBSITE_CONTENTAZUREFILECONNECTIONSTRING",
              "value": "[concat('DefaultEndpointsProtocol=https;AccountName=', variables('storageAccountName'), ';AccountKey=', listKeys(variables('storageAccountid'),'2015-05-01-preview').key1)]"
            },
            {
              "name": "WEBSITE_CONTENTSHARE",
              "value": "[toLower(parameters('caAppName'))]"
            },
            {
              "name": "FUNCTIONS_EXTENSION_VERSION",
              "value": "~3"
            },
            {
              "name": "WEBSITE_NODE_DEFAULT_VERSION",
              "value": "~10"
            },
            {
              "name": "APPINSIGHTS_INSTRUMENTATIONKEY",
              "value": "[reference(resourceId('microsoft.insights/components/', variables('applicationInsightsName')), '2015-05-01').InstrumentationKey]"
            },
            {
              "name": "FUNCTIONS_WORKER_RUNTIME",
              "value": "powershell"
            },
          ]
        }
      }

我在門戶Write-Host "$([System.Security.Cryptography.X509Certificates.X509Certificate2].Assembly.Location)"的 function 應用程序中運行以下代碼

我得到 D:\Program Files\dotnet\shared\Microsoft.NETCore.App\2.2.8\System.Security.Cryptography.X509Certificates.dll

但如果我使用 Function App 控制台：

D:\Program Files\dotnet\shared\Microsoft.NETCore.App> ls
2.2.8
2.2.8.installed
3.0.3
3.0.3.installed
3.1.3
3.1.3.installed

所以 3.1.3 存在，但 function 沒有與它一起執行。

我什至只注意到，因為我嘗試使用 System.Security.Cryptography.PbeParameters 並且缺少類型（以及其他一些 AsymmetricAlgorithm 的東西）

我該如何解決這個問題？

Answer 1

The .NET Core version is determined by the Azure PowerShell worker, which depends on the PowerShell SDK. PowerShell 6 is the only version currently available in Azure Functions, and it depends on .NET Core 2.x, this is why your PowerShell Function is executed in this context. 為了使用 .NET Core 3.x，您有以下選項：

• 推薦：等待 Azure 功能中的 PowerShell 7 支持（預計在未來 2-4 周內部署）；
• 從您的 PowerShell function 生成一個單獨的可執行文件。
