Method not found 'Boolean Microsoft.JavaScript.NodeApi.JSValue.Is()'

[moriyalb]

//JSValue.cs public bool Is<T>() where T : struct, IJSValue<T> { return T.CanCreateFrom(this); }

//MyCode //JSValue _in; if (!_in.Is<JSMap>()) { Jex.Error("implicit map value failed. invalid value "); return _out; }

Compile is success. But while running, got this error:

Error: Method not found: 'Boolean Microsoft.JavaScript.NodeApi.JSValue.Is()'.
at jj.Jex.Runtime.ProxyTypes.Tb5b61cd4_W.op_Implicit(JSValue _in)

How could this happen?

when you installing, you need to place a check in install to path and select "gcc."

I'm not sure what's going on there. Is it possible it's using an older version of the assembly at runtime than the one used to build? The JSValue.Is<>() method was added fairly recently so a slightly older version wouldn't have it.

Closing because I can't reproduce this. Try doing a clean build, and check the version of the Microsoft.JavaScript.NodeApi assembly in your output directory.
