To install it using Flatpak (which will provide a more up-to-date version of MonoDevelop) first install Flatpak with:

sudo dnf install flatpak

then run:

flatpak remote-add --user --from gnome https://sdk.gnome.org/gnome.flatpakrepo
flatpak install --user --from https://download.mono-project.com/repo/monodevelop.flatpakref

and then one can start MonoDevelop by running:
