Updating using Entity Framework can be very slow if you need to update hundreds or thousands of entities with the same expression. Entities are first loaded in the context before being updated which is very bad for the performance and then, they are updated one by one which makes the update operation even worse.
EF+ Batch Update updates multiple rows using an expression in a single database roundtrip and without loading entities in the context.
You need to update one or millions of records based on a query criteria and an expression.
The Update IQueryable extension method updates rows matching the query criteria with an expression without loading entities in the context.
You need to update one or millions of records based on a query criteria and an expression asynchronously.
The UpdateAsync IQueryable extension method updates asynchronously rows matching the query criteria with an expression without loading entities in the context.
You need to log the DbCommand information or change the CommandText, Connection or Transaction before the batch is executed.
The Executing property intercepts the DbCommand with an action before being executed.
