Describe the bug

I'm making a Blazor app with .NET 8.0.100 and try to use the Hot Reload functionality of the dotnet watch command.

It works fine at first, then usually after a few minutes of usage it becomes increasingly slow and can take up to minutes to detect a change in the code. It looks like the time to detect a change is approximately doubled each time (see screenshot below).

Expected Behavior

Relatively fast detection of changes and browser refresh when using dotnet watch.

Steps To Reproduce

• Create a new Blazor project with dotnet new blazor
• Try to make a page with dotnet watch on Ubuntu using a terminal

Exceptions (if any)

No response

.NET Version

8.0.100

Anything else?

I tried using different browsers but the problem remained.
