UPDATE: This is also happening on the web version of my Blazor application, so it's likely not a MAUI issue but a hot reload issue. Not sure how to move this to the relevant place so it can stay here I suppose, in the hope that someone knows how I can resolve it UPDATE 2: Closing this as I have posted it elsewhere as a Blazor hot reload issue. (#57107) UPDATE 3: Turns out it was a Blazor issue after all. See Answer.I have a large application built with MAUI Blazor hybrid. Was working fine until a couple of days ago so I hope this can be resolved just be clearing a cache or something. Hot reload freezes the application, memory usage shoots up then plateaus.

Resolved this finally. Turns out one of my components was hitting an infinite render cycle which could only ever be hit through hot reload.

Or any XAML framework?) has an "Infinite Layout Cycle" error, and React has similar too. |
