不允许 C++\CLI 异常规范
I'm an experienced unmanaged C++ developer, new to C++\CLI.
How come managed C++ doesnt allow exception specification?

What's the best practice for specifying exceptions my methods throw then?

大概是因为 CLR 不使用异常规范； 这大概是因为微软在研究 Java 后认为它们带来的麻烦远远超过了它们的价值。
因此，指定方法抛出哪些异常的最佳实践是不要打扰，即删除异常规范。 值得指出的是，即使在正常的 C++（即本机）世界中，大多数人要么完全避开异常规范，要么仅使用空规范来指示该方法不会抛出异常。
Presumably because the CLR doesn't use exception specifications; this in turn is presumably because Microsoft looked at Java and decided that they are far more trouble than they are worth.
So the best practice for specifying what exceptions your methods throw is to not bother, ie remove your exception specs. It's worth pointing out that even in the normal C++ (ie native) world most people either eschew exception specifications entirely, or only use the empty specification to indicate that the method does not throw.
