You can use it as long as meet our license terms

I mean, I am not working on nopcommerce source code. I just created new asp.Net core project from visual studio and in that project I implemented the functionalities of nopcommerce using your code. So it is permitted or not?

You still have to meet license terms if you copy some code from nopCommerce

I think, In this case, you shouldn't use the GPL license in nopcommerce project.
