@GuruStron: just make sure old .Net frameworks like 3.5 to 4.8 all fundamentals of asp.net will be the same even in 2023 or not? – Sudarshan Patil Jan 18 '23 at 07:25

There have been a lot of changes between Framework 4.8 and the current .Net7. So if you start learning, don't bother with the old stuff – Hans Kesting Jan 18 '23 at 10:37

There are several types of web-project, some (like webforms) are now (nearly) obsolete, others (like Blazor) new since .net5. What "fundamentals" do you mean exactly (please [edit] that into your question) – Hans Kesting Jan 18 '23 at 12:23

@HansKesting: all fundamentals of asp.net changed between frameworks 3.5 to 4.8 or not and do all fundamentals of asp.net still apply with the old framework like 3.5 to 4.8 in 2023 or not? – Sudarshan Patil Jan 18 '23 at 12:46

Most fundamental changes were introduced in ASP.NET 4.0 in 2010, so Microsoft published an article to cover them,
https://learn.microsoft.com/en-us/aspnet/whitepapers/aspnet4/breaking-changes
Ever since then, while each .NET Framework 4.x release introduced many useful features, the impact on ASP.NET itself is quite limited.
Note that since ASP.NET Core was introduced in 2016, ASP.NET 4.x received almost no big feature update in the past few years. Recent changes were added mainly to enable smoother migration to ASP.NET Core.
Nobody has the luxury time to count "how many changes" are out there. And I am not answering that either.
