Can someone please help me understand if there would be any issue regarding this transactions extension methods and its implementation? I am not sure if this could cause any issue, on locking the Db, or also if the current transactinos will be set or not.

Te method Transaction is working fine, but i wonder if it could cause any side effects.

I would need some help to address any possible issue, aappreciate it XD

extension class:

public static class TransactionExtensions
    {
        public static async Task<IDbContextTransaction> BeginTransactionAsync(this DbContext context)
        {
            if (context == null)
                throw new ArgumentNullException(nameof(context));

            if (context.Database.CurrentTransaction != null)
                throw new InvalidOperationException("An active transaction already exists.");

            return await context.Database.BeginTransactionAsync();
        }

        public static async Task CommitTransactionAsync(this DbContext context, IDbContextTransaction transaction)
        {
            if (context == null)
                throw new ArgumentNullException(nameof(context));

            if (transaction == null)
                throw new ArgumentNullException(nameof(transaction));

            if (transaction != context.Database.CurrentTransaction)
                throw new InvalidOperationException($"Transaction {transaction.TransactionId} is not the current transaction.");

            try
            {
                await context.SaveChangesAsync();
                await transaction.CommitAsync();
            }
            catch
            {
                await RollbackTransactionAsync(context, transaction);
                throw;
            }
        }

        public static async Task<T> Transaction<T>(this DbContext context, Func<Func<Task>, Task<T>> action)
        {
            using (var transaction = await context.BeginTransactionAsync())
            {
                try
                {
                    var result = await action(() => context.CommitTransactionAsync(transaction));
                    return result;
                }
                catch (Exception)
                {
                    await RollbackTransactionAsync(context, transaction);
                    throw;
                }
            }
        }

        private static async Task RollbackTransactionAsync(DbContext context, IDbContextTransaction transaction)
        {
            try
            {
                await transaction.RollbackAsync();
            }
            finally
            {
                await transaction.DisposeAsync();
            }
        }
    }

Usage:

private async Task chargeSearch(JobOfferCriteria criteria, int fetchedRecords)
        {
            var freeSearches = await GetFreeSearches();
            var charge = new OfferSearchCharge(_auth.User, fetchedRecords - (freeSearches?.Total ?? 0));
            if ((criteria.Credits ?? 0) < charge.Price) throw new Exception("Credits not enough");

            await _context.Transaction(async (commit) =>
            {
                var added = _context.Add(charge);
                await _context.SaveChangesAsync();

                charge = added.Entity;
                var credits = await _wallet.Api.ConsumeCredits(new(_auth.UserId, charge.Price));

                try
                {
                    charge.CreditsOnHold = credits;
                    charge.Confirm();
                    await commit();
                }
                catch
                {
                    _wallet.Broker.RevertCreditsConsumption(new(_auth.UserId, charge.Price));
                    throw;
                }

                return charge;
            });

            await updateAnalytics(charge);
        }
