Azure SQL Database - Transient Fault Handling doesn't work

I tried to use SQL Azure Transient fault handling, but it doesn't seem to work. My Web Service still throws a transient error. Here is my code:
public int ExecuteSqlCmd(string sql, object[] parameters)
{
return (new RetryPolicy<SqlDatabaseTransientErrorDetectionStrategy>(10, TimeSpan.FromSeconds(0.5), TimeSpan.FromSeconds(0.5))).ExecuteAction<int>(() =>
{
return this.Database.ExecuteSqlCommand(sql, sqlParams);
});
}
Every now and then, it still throws this error:
System.Data.Entity.Core.EntityException: An exception has been raised that is likely due to a transient failure. If you are connecting to a SQL Azure database consider using SqlAzureExecutionStrategy. ---> System.Data.SqlClient.SqlException: Transaction (Process ID 84) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

Any idea why? I have spent days trying to figure out the solution to this problem.

How can I solve whatever is causing SQL Server to throw "The transaction log for database 'tempdb' is full due to 'NOTHING'"?

SQL Server complains that it is full of nothing, which is, I guess, better than being full of some other things. This question has some very interesting answers, especially the one by Steven.
However, after running the script he provided, rather than seeing TRANSACTION or BACKUP as the entries in the log_reuse_wait_description column, I see only "NOTHING" and "CHECKPOINT" Every "state_desc" value is "ONLINE" and every "recovery_model_desc" is "SIMPLE". All of the "Last FULL Backup" vals are the same, too - 10/31/2014 - almost a year-and-a-half ago.
I am no DBAdmin by a long stretch, so have no idea what these things mean, or most importantly, how to prevent the err msg from occurring.
Is there anything I can do from the C# side to prevent this "full of nothing" error from occurring?
The entire err msg is:
Date: 3/7/2016 2:24:45 PM Message: Monday, March 07, 2016: Exception message: The transaction log for database 'tempdb' is full due to

Entity Framework 7 Beta5 - DbUpdateException resolution

I am having issues using the Entity Framework for simple CRUD operations.

Telerik Open Access error on string with 8000 characters

I'm trying to save 8,000 characters to a SQL Server Express database table, and this may be smaller or larger in the future, and I'm getting an exception saying that the data will be truncated.
I've already set the column to varchar(max) and don't know if there is another setting for the ORM itself.
Any help is appreciated

#makerofthings7, my best guess about the re-appearance of the error after the fix is that the model and the database are not in synchronous.
It seems that you have modified the table in the storage model in Visual Designer and in order to complete the fix, I would suggest to you to run the Update Database From Model wizard and to transfer the change in the database.
I hope this helps.
