Ef what is context

NET Core Controller method:. Given that ASP. ResetState and DbContext. Resurrect , but I wouldn't recommend calling those directly from your code, as they will probably change in future releases. Starting from.

From EF Core 3. Do not use this in production code, I mention it as it may help someone in testing depending on the scenario. As the comment on the code says;. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release. Well my opinion is that, in my experience, EF, or being any orm, does not work well under too much pressure or complex model.

And beyond, if your queries are always per id consider using a nosql or perhaps sql with just key and json. This would avoid the impedance problem between classes and tables. For your case scenario, loading things in objects that way seems very slow to me.

Really in your case, stored procedures are better because you avoid the transport of data thru the network, and sql is way faster and optimized to manage aggregation and things like that.

Within a given transaction, when SaveChanges operations performed multiple times, EF core automatically creates a savepoint for every SaveChanges call. If SaveChanges fail due to any reason, the transaction can be rolled back until last successful Savepoint.

After coming to last savepoint , the transaction is in the same state as if the remaining part of transactions has not been executed yet. It is also possible to create and name the savepoints manually. In this way, a transaction can be rolled back to one of the save points. Below code example shows how the transaction can be rolled back to a specific save point.

The methods used in below code snippet — CreateSavepoint and RollbackToSavepoint — also have async implementations. Some databases may not provide support for transactions. In such cases, such databases may throw exceptions in case transactions APIs are called. Also, the save point feature may not be supported by many databases.

In such cases, an error in save changes may leave transactions in an unknown state. This topic explores the EFContextProvider in greater detail and explains how to subclass it to get the behavior you need.
