[Aspire]: dotnet watch crashes after a few edits using Visual Studio

[davidfowl]

Using this project https://github.com/dotnet/aspire/tree/main/playground/mongo/Mongo.AppHost, running dotnet watch and making 3 edits to this line https://github.com/dotnet/aspire/blob/8abcdf7c7c5e2f0ea31db330e989450c9ccb8cdc/playground/mongo/Mongo.ApiService/Program.cs#L18.

Steps (using Visual Studio)

• Set DOTNET_DASHBOARD_UNSECURED_ALLOW_ANONYMOUS=true (to work around dotnet watch swallowing the logs and dashboard token)
• Run dotnet watch on Mongo.AppHost (you'll get 2 browser popups, one for the dashboard and one for the app)
• Go to Mongo.ApiService/Program.cs line 18 and change entries to entries2
• The entire process gets recycled instead of using hot reload (maybe rude edit detection?)
• Go to Mongo.ApiService/Program.cs line 18 and change entries2 back to entries
• Watch it crash:

@tmat did you get a chance to look at this?

@davidfowl It's having some issues with browser refresh but is applying changes correctly now.

Unable to repro anymore, assume fixed
