+
+#### Named Query Filters (.NET 10+)
+
+Starting from .NET 10, the library supports [named query filters](https://learn.microsoft.com/ef/core/querying/filters), which allow attaching names to query filters and managing each one separately. This is useful when you need multiple filters per entity type and want to selectively disable specific filters at query time:
+
+```csharp
+// using TinyHelpers.EntityFrameworkCore.Extensions;
+protected override void OnModelCreating(ModelBuilder modelBuilder)
+{
+    // Apply named filters to all entities that implement the corresponding interfaces.
+    modelBuilder.ApplyQueryFilter<ISoftDeletable>("SoftDelete", e => !e.IsDeleted);
+    modelBuilder.ApplyQueryFilter<ITenantEntity>("TenantFilter", e => e.TenantId == currentTenantId);
+}
+```
+
+Named filters can then be selectively disabled in specific queries:
+
+```csharp
+// Disable only the soft-delete filter, keeping the tenant filter active.
+var allItems = await context.People.IgnoreQueryFilters(["SoftDelete"]).ToListAsync();
+```
