Small Jet Captain reported after takeoff the nose gear would not retract. After troubleshooting and aggressive maneuvering; the crew was able to extend the gear and land safely.

Narrative

After departure from ZZZ; our landing gear was showing the mains up and locked with the nose wheel still unlocked. We were briefed to recycle the gear to fix the issue. Upon recycling the gear; the nose was still showing unlocked. Now; the mains were locked and the nose was unlocked. The gear handle was now stuck in the down position with a weight on wheels miscompare message showing on the CAS. We ran the appropriate checklist and tried pulling the D ring handle to get the nose unlocked. This did not work. We did a low pass to verify the indication and the Ops crew verified our nose wheel was still up. We asked to fly around for a bit to make calls to our company. After exhausting our options to get the nose down; we maneuvered aggressively to try to get it down. We were eventually able to get it down and land safely. All messages on the CAS cleared. Priority was given to us to maneuver around the ZZZ1 area. Approach; Tower; Ground and Ops did everything they could to help us. The crew in the plane used CRM to reach out to outside sources for help. The aircraft manufacturer maintenance was communicating with us to help with ideas. In the end; it turned out well. Crew; passengers and plane were safe.
