是否可以在app.config中的“supportedRuntime”中指定.NET Service Pack？

Question

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).

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>

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

Thanks!

Edit: 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.

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.

Eg:

Warning: System.MissingMethodException: Method not found: 'Boolean System.Threading.WaitHandle.WaitOne(Int32)'. while resolving 0xa0000e1 - System.Threading.WaitHandle.WaitOne.

Answer 1

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

<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.

Answer 2

Try this (for .net 2.0 sp2):

<supportedRuntime version="2.0.50727.1433" />

.NET Framework versions here.
