true instanceof Object //=> false
false instanceof Boolean //=> false
false instanceof Object //=> false

ome-literals

while in c#
all should return true

C# example:
var b = "aaaa";
return (b is JsString); // should return true but return false

The native js types are currently configured to generate standard 'instanceof' 
when using the 'is' keyword on them. This behavior can be configured 
differently in any project, but currently, 'is' converts to 'instanceof' with 
any js issues related to it.  You can remove this behavior, and then implement 
the 'Is()' global method instead.
Please confirm before I close this issue.

How can I force SharpKit to use Is() in all types in project?

You should set NativeCasts=false on types that you wish to disable it. For 
native types, you might have to compile your own SharpKit.JavaScript.

Hi,
>> For native types, you might have to compile your own.

It is really not a solution, we constantly got your latest version and don't 
want to work with an un-official version. that solution may useful for 
single-time usage!
Wish you provide an attribute in assembly level. 
Regards
