Can you fix/update the old scripts at Unity.2019.1?

After I updated Unity 2019.1.4f1 and Visual Studio 2017(and 2019) I feel like my 2018 scripts is broken/not loaded. Even I can't find the VS2019 at Preferences. Why the Add Component Scripts are changed to Packages. please fix or update the Unity problem. thanks.![alt text][1] ![alt text][2] [1]: https://cdn.discordapp.com/attachments/430976562838634519/585430598731038721/unknown.png [2]: https://cdn.discordapp.com/attachments/430976562838634519/585430821952028702/unknown.png
