我有一个运行良好的。NET 2.0 SP2，但未能在.NET 2.0 RTM正常运行的应用程序。 （供参考：它调用一个方法的托管DLL，它是一个包装了原生的DLL USB编程失败时）

I have an application that runs fine on .Net 2.0 SP2, but fails to run properly on .NET 2.0 RTM. (FYI: It fails when calling a method a managed DLL that is a wrapper for a native DLL for USB programming).

我知道你可以给支持运行时在C＃.NET应用程序

I know you can give supported runtimes in the app.config of a C# .NET application

  <startup>
    <supportedRuntime version="v2.0.5727" />
    <supportedRuntime version="v4.0" />
  </startup>

不过，是不是也可以指定一个特定的服务包版本？

However, is it also possible to specify a specific Service Pack version?

谢谢！

编辑：我现在发现哪种方法之间的2.0和2.0 SP2失败。它是WaitHandle.WaitOne（INT），将其加入2.0 SP。

I did now find out which method fails between 2.0 and 2.0 SP2. It is WaitHandle.WaitOne(int) which was added in 2.0 SP1.

一个技巧其他人有问题，编译器不会说什么，但如果你NGEN有问题的运行可执行文件，它确实给你确切的错误。

A tip for everyone else having the problem, the compiler doesn't say anything but if you ngen the executable with the problematic runtime, it does give you the exact error.

例如：

Warning: System.MissingMethodException: Method not found: 'Boolean System.Threading.WaitHandle.WaitOne(Int32)'. while resolving 0xa0000e1 - System.Threading.WaitHandle.WaitOne.
11/11/2010 01:54:07 [3620]: Method not found: 'Boolean System.Threading.WaitHandle.WaitOne(Int32)'. while compiling method XXX

很好的解释可以发现此处为什么这是不可能的。你可以找到一个SO响应here以满足您的需求。

Great explanation can be found here on why this is not possible. You can locate a SO response here to address your needs.

＆LT; supportedRuntime＆GT; 不实际工作的方式，因为3.5框架使用2.0运行时。您只能指定的运行时的那样，不是的框架的，而元素只EX presses preference，没有需求。

<supportedRuntime> doesn't actually work that way, because the 3.5 framework uses the 2.0 runtime. You can only specify runtimes that way, not frameworks, and the element only expresses preference, not demand.
