What you are looking for is a Batch Delete Library which deletes multiple records in a database from a LINQ Query without loading entities.

Multiple libraries supporting this feature exist.

You can find the list here: Entity Framework Batch Delete Library

Disclaimer: I'm the owner of the project Entity Framework Plus

// using Z.EntityFramework.Plus; // Don't forget to include this.

// DELETE directly in SQL (without loading entities)
db.Tables.Where(_ => _.Column == 'SomeRandomValue'
 && _.Column2 == 'AnotherRandomValue')
 .Delete();

// DELETE using a BatchSize 
db.Tables.Where(_ => _.Column == 'SomeRandomValue'
 && _.Column2 == 'AnotherRandomValue')
 .Delete(x => x.BatchSize = 1000);

Wiki: EF+ Batch Delete

It's a bit broken, try

db.Tables.RemoveRange(
 db.Tables
 .Where(_ => _.Column == 'SomeRandomValue'
 && _.Column2 == 'AnotherRandomeValue').AsEnumerable().ToList()
);
db.SaveChanges();

var db1 = db.Tables
 .Where(_ => _.Column == 'SomeRandomValue'
 && _.Column2 == 'AnotherRandomeValue').AsEnumerable().ToList();
db.Tables.RemoveRange(db1);
db.SaveChanges();

Use an Variable to Store Removable list and pass it to RemoveRange().

I Usually do like this, and That's Work.
Hope This also work in your case.

Why don't you just have an adapter to the database and just send the appropriate delete command like in your example?

Step back and think. Do you really want to download the records from the database in order to delete them? Just because you can doesn't make it a good idea.

Perhaps you could consider deleting the items from the database with a stored procedure? EF also allows to do that...

I'm dealing with this myself, and agree with Adi - just use sql.

I'm cleaning up old rows in a log table, and EF RemoveRange took 3 minutes to do the same thing this did in 3 seconds:

DELETE FROM LogEntries WHERE DATEDIFF(day, GETDATE(), Date) < -6

Date is the name of the column containing the date. To make it correct, use a parameter, of course, like this:

 context.Database.ExecuteSqlCommand
 ("DELETE FROM LogEntries WHERE DATEDIFF(day, GETDATE(), Date) < @DaysOld", new System.Data.SqlClient.SqlParameter(
 "DaysOld", - Settings.DaysToKeepDBLogEntries));

Note that there are a lot of rows involved in my case. When I started the project and didn't have a lot of data, RemoveRange worked fine.

I have met this problem as well, this is my workaround with a library called entityframework.extended by LoreSoft (which you can get it from nuget package manager):

1.You first query them your list.
2.Then use .Delete(), which is a function from .extended library.

var removeList = db.table.Where(_ => _.Column == 'SomeRandomValue'&& _.Column2 == 'AnotherRandomValue') 
removeList .Delete();

Note: According to Entity Framework EF extended, as of the time writing, this entityframework.extended is deprecated. Therefore one might need to consider entityframework plus library. While i have not tested on the plus extension, but i can confirmed working it works using .extended library.
