我正在使用Visual Basic 2008 Express Edition，现在我正在创建一个文本编辑器。它在我的系统上运行得很好，但是当我试图在我朋友的系统上运行它时，我收到了这个错误：
See the end of this message for details on invoking

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

************** 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.
操作系统是带有.NET framework 2.0的Windows XP。
我不想使用.NET framework 3.5，因为它的大小超过200 MB。我的代码如下。这段代码真的需要.NET framework 3.5吗？
Public Sub ClipboardEnglish(ByVal StrSearch As String)
If IO.File.Exists(Application.StartupPath & "\eng.txt") Then
If NotifyIcon1.Visible = True Then
Dim words() As String = IO.File.ReadAllLines(Application.StartupPath & "\eng.txt")
Dim startwiths() As String = (From word In words Where LCase(word).StartsWith(LCase(StrSearch & " ")) Select word).ToArray
For Each startwith In startwiths
Dim meanings() As String
startwith = Replace(LCase(startwith), LCase(StrSearch) & " ", "")
meanings = Replace(startwith & ",", ", ", ",").Split(New Char() {","c})
For Each mean In meanings
If Not mean = " " AndAlso Not mean = "" Then
If mean.Length > 100 Then
mean = mean.Substring(0, 100) & "..."
End If
If Not TSMIurdu.DropDownItems.Count = TSEnglishcount.Text Then
TSMIurdu.DropDownItems.Add(mean)

Revision 42是.NET 2.0的原始RTM版本。在.NET 3.5之前，System.Core Version = 3.5.0.0无法使用。你的朋友至少没有它，因为他在永远不会使用Windows Update时表现出色。除了他通常从Windows Update获得的.NET 3.0,3.5和3.5 SP1更新之外，自版本42以来已经发布了许多稳定性和安全补丁。仅在上周发布了另一个。永远不要接受他的机器上的任何可执行文件，他们可能有cooties。
