I'm facing this issue too. My solution is based on .NET Core 3.x. In my case I found that the updates applied to .cshtml files work only on "Start Without Debugging", useful for now but not ideal for debugging. Both the Start(with debugging) from kestrel(console) and IIS have this issue.
Here's the Solution and Project file:
collanon.zip

Thanks @thepra. Bringing this up for triage on monday. In the meantime, can you please host your projects as a github repo, as it's much simpler that way to look into the code and navigate

[thepra]

Mmmmm, it's more of a closed source web app(already running as collAnon) than an open source project.
But still I could open up some non-business-core pieces like Startup.cs or Program.cs, etc. in a new project if it can help, just let me know.

To enable runtime-compilation it's now required to use a special NuGet package. You can read more about how to enable runtime-compilation here: https://docs.microsoft.com/en-us/aspnet/core/mvc/views/view-compilation?view=aspnetcore-3.0#runtime-compilation

Ok... but should I isolate it like this?

#if DEBUG 
    .AddRazorRuntimeCompilation()
#endif

because adding runtime compilation in Release/Production doesn't make that much sense. 🤔

@thepra That sounds like a valid solution.
