我有一个VB.net应用程序，它使用自定义可序列化类来持久保存配置设置。在启动时，我反序列化配置文件。这在调试器中完美运行。我在Visual Studio中运行应用程序，它调用LoadSettings函数，并实例化该对象。但是，一旦我构建了可执行文件并运行它，它就会生成一个异常。有谁知道调试器和编译代码之间的行为有何不同？
配置文件的创建方式是序列化类Settings的对象，并使用StreamReader对象将其写入文件。很简单，我一直都这么做。
这是子程序：
Private Sub LoadSettings(FromFile As String)
Dim ser As New XmlSerializer(GetType(UtilityClasses.Settings))
Dim reader As New StreamReader(FromFile)
Settings = ser.Deserialize(reader)
reader.Close()
End Sub
并且，在ser.Deserialize()调用中，它引发了此异常：

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
