还有Salamander，这是一个来自Remotesoft的原生。net编译器和链接器，可以在没有。net框架的情况下部署应用程序。我不知道它是否符合它所宣称的。

Here's one idea: you could have a server hosted by your company that all instances of your software need to connect to. Simply having them connect and verify a registration key is not sufficient -- they'll just remove the check. In addition to the key check, you need to also have the server perform some vital task that the client can't perform itself, so it's impossible to remove. This of course would probably mean a lot of heavy processing on the part of your server, but it would make your software difficult to steal, and assuming you have a good key scheme (check ownership, etc), the keys will also be difficult to steal. This is probably more invasive than you want, since it will require your users to be connected to the internet to use your software.

Jared指出de4dot声称能够反编译它。

.NET Reactor provides complete protection for your sensitive intellectual property by converting your .NET assemblies into unmanaged processes which cannot be understood as CIL, and which no existing tool can decompile. Hackers have no access to any intelligible form of your source. Powerful and flexible, the .NET Reactor licensing features allow you to enforce your license conditions and protect your revenue stream by using hardware and software locks. The license manager can build trial or permanent licenses, in a matter of seconds. A fully documented software development kit (SDK), complete with examples, allows you to call the licensing system directly from your code, allowing you to create custom extensions to the licensing system.

客户端上运行的任何东西都可以被反编译和破解。混淆只会让它更难。我不了解你的应用程序，但99%的情况下，我认为不值得这么做。

如果微软能想出一个解决方案，我们就不会有盗版的Windows版本，所以没有什么是非常安全的。下面是来自Stack Overflow的一些类似问题，您可以实现自己的保护方式。如果你正在发布不同的版本，那么你可以针对不同的版本采用不同的技术，这样当第一个版本被破解时，第二个版本就可以接管。

只是补充一个警告:如果你打算使用混淆，检查一切仍然工作!混淆可能会改变类名和方法名。因此，如果你使用反射来调用某些方法和/或类(就像在插件架构中)，你的应用程序在混淆后可能会失败。另外，堆栈跟踪对于跟踪错误可能是无用的。
