Returns the first element in a sequence that satisfies a specified condition.
public static Task<TSource> FirstOrDefaultAsync<TSource>(this IAsyncEnumerator<TSource> source, CancellationToken token = default, bool disposeSource = true)
Returns the first element in the IAsyncEnumerator<T>, or a default value if no element is found.
public static Task<TSource> FirstOrDefaultAsync<TSource>(this IAsyncEnumerator<TSource> source, Func<TSource, bool> predicate, CancellationToken token = default, bool disposeSource = true)
Returns the first element in a sequence that satisfies a specified condition, or a default value if no element is found.
