调用assembly.getExportedTypes（）时会抛出filenotfoundexception（）

Question

即使在安装应用程序之前已经安装了.NET 2.0 Framework运行时，我在剥落的XP SP3 X86虚拟机上运行.NET 2.0应用程序时会遇到此错误。

Exception Source:      mscorlib
Exception Type:        System.IO.FileNotFoundException
Exception Message:     Could not load file or assembly 'WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
Exception Target Site: GetExportedTypes

---- Stack Trace ----
   System.Reflection.Assembly.GetExportedTypes()
       XSplit.Core.exe: N 00000
   XSplit.Core.Capture.ChannelAddinManager.#Dm( As String)

       XSplit.Core.exe: N 00534
   XSplit.Core.frmLogin..ctor(args As String[])
       XSplit.Core.exe: N 01263

产生此错误的相关代码是

var assembly = Assembly.LoadFrom(dllFile);
var assemblyTypes = assembly.GetExportedTypes();

即使在安装框架2.0 SP2之后，此错误仍会丢弃。

你们对为什么这样的线索有什么线索？

WindowsBase组件直到.NET 3.0才能使用。如果您想在没有例外的情况下运行此代码，则需要在计算机上安装3.0，2.0不够好。检查加载项项目的构建设置，并确保其不引用任何WPF组件。
