ASP.NET Core vs RichFaces

As a medium level .Net programmer trying to implementing a website, I decided to go through the Asp.Net Core. I found some tutorials on the web and started learning; however, I faced a problem. Even though I have been working with .Net and C# (mostly with unity game engine, which led to a quite amazing mobile game, published on a Persian app store) for two years or even more, by start learning Asp.Net Core, I found out that I do not know .Net as much as I expected. There were some things I should have learned before.

I searched for other frameworks, and Django was a popular one. Besides, I have planned to learn Python for machine learning. The website I want to make (with a small team) is nearly similar to Khan Academy. (We are going to use React for front-end)

So, What should I do? Continue working on .Net core with its amazing new features, or start getting into the Python and Django?

Your advice accompanied by reasons will be greatly appreciated!

I have a mission to make a web application for my organization (engineering consultant). With the following bullet points that the new web app has to cover, what is the right tool?

1. It should be able to display employee data and project data. For example, when searching the name of Mr. Peter Parker, I should be able to click on the name to see his personal profile and also a list of construction projects he is or was a part of. Also, if I click on a project name, say Project ABC building, it should show me the detail of this project (who is the client, who works on this project, where, start-finish dates, etc.)

2. It should be able to sync with the database from Microsoft Access.

(optional) 3. The user of this web app should be able to propose a rotation of role (Ex. Boss might want Mr. Peter Paker to work in another project next month, he can just drag Peter into XYZ Building.)

For context, I currently use JavaScript (React) and Python (Flask) in my daily routine.

I need your help in choosing either Spring Boot or ASP.NET Core. Both frameworks seem to have mature ecosystems. I would like to hear your thoughts on the following points:

• Difficulty level of both frameworks
• Level of community support
• Career prospects i.e do Spring based jobs pay more or vice versa
• which one will be helpful if I decide to transition towards a more specialized field like data engineering.

I am asking this because it is something that I am also exploring in parallel. I know that Python and #SQL play a huge role in big data.
