Methods

AllAsync<TSource>(IQueryable<TSource>, Expression<Func<TSource,Boolean>>, CancellationToken)	Asynchronously determines whether all the elements of a sequence satisfy a condition.
AnyAsync<TSource>(IQueryable<TSource>, CancellationToken)	Asynchronously determines whether a sequence contains any elements.
AnyAsync<TSource>(IQueryable<TSource>, Expression<Func<TSource,Boolean>>, CancellationToken)	Asynchronously determines whether any element of a sequence satisfies a condition.
AsAsyncEnumerable<TSource>(IQueryable<TSource>)	Returns an IAsyncEnumerable<T> which can be enumerated asynchronously.
AsNoTracking<TEntity>(IQueryable<TEntity>)	The change tracker will not track any of the entities that are returned from a LINQ query. If the entity instances are modified, this will not be detected by the change tracker and SaveChanges() will not persist those changes to the database.
AsNoTrackingWithIdentityResolution<TEntity>(IQueryable<TEntity>)	The change tracker will not track any of the entities that are returned from a LINQ query. If the entity instances are modified, this will not be detected by the change tracker and SaveChanges() will not persist those changes to the database.
AsTracking<TEntity>(IQueryable<TEntity>, QueryTrackingBehavior)	Returns a new query where the change tracker will either keep track of changes or not for all entities that are returned, depending on the value of the 'track' parameter. When tracking, Any modification to the entity instances will be detected and persisted to the database during SaveChanges().
