Future of Asp.Net as compare to Java

If you are needed to handle ASP.NET Core tasks in current company, then happily continue with it, you won't regret its really much better than saying no to management. After some period if you want you can move back into java.

Changing tech is not a problem especially java and .net skills are both almost similar and relatable and transferable(I am not much experienced, as per my little exposure).

C# with ASP.NET Core is better than Java In my opinion, ASP.NET Core is very easy for backend development, it is constantly updated and upgraded, is bit faster compared to Java in certain instances (depending on how you test it, but response time is better in C# and it can handle higher loads). In my opinion C# is the future because now you can use it on all different OS.

Both are used for enterprise developments. In recent periods, .Net is very stimulating and getting picked up rapidly in various places. while seeing the big demand, community, support, ASP.NET Core is advisable.
