Fix ObjectDisposedException From Scoped Services
Compile-time guidance for scope leaks, services escaping scopes, and using resolved services after the scope ends in ASP.NET Core and .NET apps.
Problem guides
These pages are written around the search queries maintainers and teams actually use when DI issues show up in logs, reviews, or startup failures.
Problem guide
Compile-time guidance for scope leaks, services escaping scopes, and using resolved services after the scope ends in ASP.NET Core and .NET apps.
Problem guide
Use compile-time diagnostics to catch singleton-to-scoped and singleton-to-transient lifetime mismatches before stale state or thread-safety bugs ship.
Problem guide
Catch BuildServiceProvider misuse during service registration so composition code does not silently create a second service container.
Problem guide
Find missing registrations and implementation mismatches at compile time instead of learning about them from runtime activation exceptions.
Problem guide
Surface hidden dependencies, service locator drift, and direct IServiceProvider injection in application code before it hardens into architecture debt.
Problem guide
Identify transient services implementing IDisposable or IAsyncDisposable that the container will not track or dispose automatically.
Problem guide
Find classes that are accumulating too many constructor dependencies so SRP drift shows up in IDE diagnostics and CI instead of code-review debates.
Problem guide
Catch ignored TryAdd calls and duplicate registrations that change single-service resolution behavior in Microsoft.Extensions.DependencyInjection.
Problem guide
Catch CreateScope usage in async flows so async-disposable services are cleaned up with the correct scope pattern.
