After changing the data in the SQL database, they are not immediately read.

.Net Core, MVC-6, EF-7
writing data to Postgres SQL:

db.SaveChanges(); db.Database.CommitTransaction(); 

After that I try to read this data using LINQ-SQL - there is no recorded data. Reload page - i.e. new query - the recorded data using LINQ-SQL read!

Actually the question is why the recorded data is not read after the record and what should I do to be read?

All code in one function. No Async or await.

 db.Database.BeginTransaction(); 

I change the base:

 List<License> DelLicenses = db.Licenses .Where(u => u.UserId == UserId && u.ProductId == ProductId).ToList(); db.RemoveRange(DelLicenses); db.SaveChanges(); ....; db.SaveChanges(); db.Database.CommitTransaction(); 

And here it is not read:

 List<License> DelLicenses = db.Licenses .Where(u => u.UserId == UserId && u.ProductId == ProductId).ToList();
