dotnet watch doesn't react when changing .razor files in referenced projects #22219
Description
dotnet watch is meant to identify files in referenced projects that should trigger a refresh. This does work correctly for .cs files, but not for .razor files.
Repro
Using .NET Core 3.1.300 (on Mac, but probably is the same on other platforms):
dotnet new blazorwasm --hosted -o MyAppcd MyAppdotnet watch -p Server --list
Expected result: Lists the files (including .razor files from the Client project)
Actual: Gets the paths wrong. Output is:
path/MyApp/Server/Pages/Error.cshtml
path/MyApp/Server/Pages/Shared/_Layout.cshtml
path/MyApp/Server/Controllers/WeatherForecastController.cs
path/MyApp/Server/Pages/Error.cshtml.cs
path/MyApp/Server/Program.cs
path/MyApp/Server/Startup.cs
path/MyApp/Server/MyApp.Server.csproj
path/MyApp/Server/App.razor
path/MyApp/Server/Pages/Counter.razor
path/MyApp/Server/Pages/FetchData.razor
path/MyApp/Server/Pages/Index.razor
path/MyApp/Server/Shared/MainLayout.razor
path/MyApp/Server/Shared/NavMenu.razor
path/MyApp/Server/Shared/SurveyPrompt.razor
path/MyApp/Server/_Imports.razor
path/MyApp/Client/Program.cs
path/MyApp/Client/MyApp.Client.csproj
path/MyApp/Shared/WeatherForecast.cs
path/MyApp/Shared/MyApp.Shared.csproj
Notice Server/Pages/Counter.razor? This should be Client/Pages/Counter.razor. I'm not sure how it's computing these incorrect paths to non-existent files.
Also if you try editing and saving one of the Client/**/*.razor files, dotnet watch won't respond.
