Windows 10 IoT仪表板-无法识别的配置部分启动

Question

我正在尝试安装Windows 10 IoT核心版仪表板，但是ClickOnce安装程序失败。

我得到的日志文件的顶部是：

PLATFORM VERSION INFO
    Windows             : 10.0.17763.0 (Win32NT)
    Common Language Runtime     : 4.0.30319.42000

SOURCES
    Deployment url          : https://iottools.blob.core.windows.net/iotdashboard/Windows10IoTCoreDashboard.application

ERROR SUMMARY
    Below is a summary of the errors, details of these errors are listed later in the log.
    * Activation of https://iottools.blob.core.windows.net/iotdashboard/Windows10IoTCoreDashboard.application resulted in exception. Following failure messages were detected:
        + Configuration system failed to initialize
        + Unrecognized configuration section startup. (**C:\Windows\Microsoft.NET\Framework64\v4.0.30319\dfsvc.exe.Config** line 2)

dfsvc.exe.Config文件为：

<configuration>
    <appSettings>
      <add key="EnableWindowsFormsHighDpiAutoResizing" value="true"/>
    </appSettings>
    <runtime>
      <!-- AppContextSwitchOverrides values are in the form of 'key1=true|false;key2=true|false -->
      <!-- Enabling newer accessibility features (e.g. UseLegacyAccessibilityFeatures.2=false) requires all older accessibility features to be enabled (e.g. UseLegacyAccessibilityFeatures=false) -->
      <AppContextSwitchOverrides value="Switch.System.Net.DontEnableSchUseStrongCrypto=false;Switch.UseLegacyAccessibilityFeatures=false;Switch.UseLegacyAccessibilityFeatures.2=false;Switch.UseLegacyAccessibilityFeatures.3=false;Switch.System.Windows.Forms.UseLegacyImages=false" />
    </runtime>
</configuration>

到目前为止，我发现的唯一想法是运行NetFxRepair工具并删除ClickOnce缓存，但是它们似乎都没有改变。我已经安装了VS2019 Previe3w和VS2017
