What's the difference between dotnet watch and Hot Reload in Visual Studio?

[LuohuaRain]

Interestingly, in my own experimentation, I've found dotnet watch CLI to be faster than Hot Reload in Visual Studio (Blazor Server).

I am not sure what's the differences between them?

From what I recently heard, they are not exactly the same. Watch watches for files to change, then recompiles, and restarts the app. "Hot reload" is the reload mechanism.

In Visual Studio there is no such watch functionality, at least not the same.

My guess is that Dotnet Watch and VS both integrate with the same basic Hot Reload functionality in different ways.

They are both implementations of the Edit and Continue support; VS presumably has some built-in "trigger EnC for these files", while dotnet watch presumably does similarly, but as a CLI tool.

Hot reload is not stable at all. Sometimes it appears and sometimes it doesn't without any reason you can think of.
