我有各种版本的.NET Framework安装在运行XP Professional的远程计算机上（版本1.1直通4.0）。我已经安装了无功扩展得的好办法。

I've various versions of the .NET Framework (versions 1.1 thru 4.0) installed on a remote machine running XP Professional. I've installed Reactive Extension too for good measure.

我也有它的作品在我的机器，因为它引用的System.Threading发现这里上的应用程序： C：\ Program Files文件\微软无扩展\ REDIST \ desktopV2 \ System.Threading.dll

I also have an application which works on my machine because it references System.Threading found here: C:\Program Files\Microsoft Reactive Extensions\redist\desktopV2\System.Threading.dll

我有两个版本在GAC也。

I have two versions of the DLL in the GAC also.

两个问题：

我）为什么Visual Studio的决定，这是版本（实例）来引用，当我从列表中选择，而不是浏览到该文件？

i) Why did Visual Studio decide that this is the version (instance) to reference when I chose from the list rather than browsing to to the file?

二）为什么不的System.Threading在远程计算机上存在吗？ （我以为是框架的核心组成部分）

ii) Why does System.Threading not exist on the remote machine? (I thought it was a core part of the Framework)

感谢

推荐答案

System.Threading.dll中添加了.NET 4.0（虽然命名空间的的System.Threading 自V1已经出现）。接收包括版本System.Threading.dll的被反向移植到.NET 3.5 SP1。

System.Threading.dll was added in .NET 4.0 (though the namespace System.Threading has been around since v1). Rx includes a version of System.Threading.dll that was backported to .NET 3.5 SP1.

这听起来像你的目标.NET 3.5。在这种情况下，运行时不会加载了一块4.0只System.Threading.dll（显然）。你装会失败，除非你包括接收版本System.Threading.dll连同你的程序。

It sounds like you're targeting .NET 3.5. In this case, the runtime won't load a 4.0-only System.Threading.dll (obviously). Your loading would fail unless you included the Rx version of System.Threading.dll along with your program.

要直接回答的问题：

要解决你的问题，要么你的程序的目标。NET 4.0或包括接收的System.Threading.dll随着你的程序。

To solve your problem, either have your program target .NET 4.0 or include Rx's System.Threading.dll along with your program.

P.S。我建议您升级到RX的最新版本。该 desktopV2 文件夹没有被用于最后的几个版本。升级时，先卸载旧版本 - 它的工作原理更好的办法

P.S. I recommend upgrading to the latest version of Rx. The desktopV2 folder hasn't been used for the last few releases. When upgrading, uninstall the old version first - it works better that way.
