Hot reload error: System.AggregateException: One or more errors occurred. (Format of the executable (.exe) or library (.dll) is invalid.) #122628
Description
Description
I'm running my Aspire-based project with dotnet watch run --project "./Ogma3.AppHost/Ogma3.AppHost.csproj". Hot reload works.
Eventually, though, it randomly throws the forementioned error after a file change, and from that point on it stops working completely. The application itself does not crash, it just doesn't hot reload anymore.
Reproduction Steps
I tried recreating this issue with a simple project, but failed. It could very well be a function of complexity.
Expected behavior
dotnet watch ⌚ File updated: F:\VS Projects\Ogma3\Ogma3\Pages\Index.cshtml
dotnet watch 🔥 [Ogma3.AppHost (net10.0)] Hot reload succeeded.
Actual behavior
dotnet watch ⌚ File updated: F:\VS Projects\Ogma3\Ogma3\Pages\Index.cshtml
dotnet watch 🔥 [Ogma3.AppHost (net10.0)] Hot reload succeeded.
dotnet watch ⚠ [Ogma3 (net10.0)] Exception from 'Microsoft.AspNetCore.Mvc.HotReload.HotReloadService.UpdateApplication': System.AggregateException: One or more errors occurred. (Format of the executable (.exe) or library (.dll) is invalid.)
