FYI, if you are getting a NameError using RunString that usually means that
you run needs to do some imports remember that RunString creates
totally new global local namespace, so you¹ll need to import any names you
your code snippet.
hope this helps,

> - The RunString works only if the code does not have any .net objects or does
> not include any .net exceptions
> - If the code sent to RunString includes a .net object e.g. obj, then
> RunString always returns in NameError, obj is not defined
> 3. Strangely, if I run the console application, it is able to work with .net

> 4. Is this because of the new dictionary created while in RunString?
