DLL creation y not possible??

Question

Hi friends

Well coming to pint 

Cant c# developers lets say .net developers cant create libraries like Write & read etc which communicates with hardware if i am not wrong ??

is it right that some C# Pre-defined libraries are not possible to create using our .Net languages so we implement them using other languages c++,c, forton etc and re-implement here. 

I am deeply hurted the thing why cant we create a libraries which can communicate with hardware as our C# or .net lang's is more advanced then c++,c etc ??

If anything wrong in my question please correct me :)

 just please share your valuable view on it , i am dying to know it
