Question: Is there a way to use something like substring for showing only a certain number of words, so that it doesn't cut the words, but cuts on the spaces only? I want to do this for shortening a description when showing the item.

Answer: 
NuGet.org will remove support for TLS 1.0 and 1.1 in April, 2020
We realize adapting to change can take time, and we want to share our plans early. To help minimize the number of affected users, we plan to make this change in two stages:

* **February 2020**: Temporarily remove support for TLS 1.0/1.1 in 3 timezones, for 4 hours each, to ensure overlap with normal working hours across the globe
* **April 2020**: Permanently remove support for TLS 1.0/1.1

If you need more about next steps, please refer to [doc](https://devblogs.microsoft.com/nuget/deprecating-tls-1-0-and-1-1-on-nuget-org/)
I was also able to solve this problem by updating nuget.exe to a newer version (2.8 to 5.0).
