I am trying to secure a transaction through Entity Framework. When I use BeginTransaction
, ASP.NET throws an exception:
The configured execution strategy 'SqlServerRetryingExecutionStrategy' does not support user initiated transactions. Use the execution strategy returned by 'DbContext.Database.CreateExecutionStrategy()' to execute all the operations in the transaction as a retriable unit.
This is my code inside the repository
public async Task<EvaluationFormQuestionAnswer> AddScore(EvaluationFormQuestionAnswer evaluationFormQuestionAnswer)
{
evaluationFormQuestionAnswer.Id = Guid.NewGuid();
evaluationFormQuestionAnswer.EvaluatorId = _identityService.Identity.CurrentAccount.Id;
using (var transaction = _dataContext.Database.BeginTransaction())
{
try
{
var result = await _dataContext.EvaluationFormQuestionAnswer.AddAsync(evaluationFormQuestionAnswer);
await _dataContext.SaveChangesAsync();
transaction.Commit();
return result.Entity;
}
catch (Exception ex)
{
transaction.Rollback();
throw new ArgumentException("Error", ex);
}
}
}
This should work:
var strategy = _dataContext.Database.CreateExecutionStrategy();
await strategy.ExecuteAsync(async () =>
{
...<Your Using Block>...
});
Wrap it in the execution strategy as shown above and your code should work fine.
