dotnet watch hot reloads for all non-code files - potential infinite reload loop

[seangwright]

Describe the bug

I'm running dotnet watch in the directory of an ASP.NET Core 8.0 application using the .NET 9 SDK.

My app generates non-code files in the ~\App_Data directory as part of a background process (this includes binary, xml, json, and other non code files). When this happens, dotnet watch records the files being created or modified and will even hot reload

For example

dotnet watch ⌚ Files added: .\App_Data\LuceneSearch\QANDA_SEARCH\i-g0000059-p_False\write.lock, .\App_Data\LuceneSearch\QANDA_SEARCH\i-g0000059-p_False_taxonomy\write.lock
dotnet watch ⌚ Files added: .\App_Data\LuceneSearch\QANDA_SEARCH\i-g0000059-p_False\write.lock, .\App_Data\LuceneSearch\QANDA_SEARCH\i-g0000059-p_False_taxonomy\write.lock
dotnet watch ⌚ No hot reload changes to apply.

I have tried ignoring specific files but none of the recommendations work. Even if they did work, there's no reason I should have to explicitly ignore some .txt files in App_Data to keep my app from reloading.

To Reproduce

1. Clone https://github.com/seangwright/dotnet-watch-dotnet-sdk9-bug
2. Run dotnet watch
3. See home page load in browser
4. See infinite number of .txt files created in App_Data\Test because dotnet watch keeps reloading the page

Exceptions (if any)

dotnet watch should not process files that have nothing to do with rebuilding or hot-reloading my .NET application.
