Thanks for contacting support.
I am afraid none of our current API's supports .NET Core framework. However we are going to release a new product line for .NET Core but I am afraid currently we are not certain about the exact timelines. However we expect to have one of the release versions in Q3-2017 (but still its not a promise). As soon as the new product line becomes available, we will let you know.
We are sorry for this inconvenience.
