Is it ok to use MVC + web api architecture together?

Question

ASP.NET

There is an MVC application, with its own registration and authentication, I wrote a simple real-time chat on signalR, I was told that it is better to do the chat through the web api, and the question is whether it is normal to combine web api + mvc in 1 project, it turns out that I have ordinary pages there will be .cshtml and a SPA .html chat page, there is no complete understanding of what is right and what is wrong and what experienced guys usually do and how in such cases

Answer 1

Why not.
Just note that it is better to move the statics to separate locations for nginx so as not to drive kestrel in vain
