Entity Framework Core 3 raw SQL missing methods

I'm trying to use EF Core 3 to delete all rows from a table like:

db.MyTable.ExecuteSqlRaw("delete from MyTable;");

But I get the error:

DbSet' does not contain a definition for 'ExecuteSqlRaw' and no accessible extension method 'ExecuteSqlRaw' accepting a first argument of type 'DbSet' could be found (are you missing a using directive or an assembly reference?)

The Microsoft breaking changes page for EF Core 3 does not offer any advice on if there are special packages required to enable this:

https://docs.microsoft.com/en-us/ef/core/what-is-new/ef-core-3.0/breaking-changes#fromsql-executesql-and-executesqlasync-have-been-renamed

These are the Nuget packages I have installed:

<PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.0.0" />
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="3.0.0" />
<PackageReference Include="Newtonsoft.Json" Version="12.0.2" />
<PackageReference Include="System.Linq" Version="4.3.0" />
<PackageReference Include="System.Linq.Expressions" Version="4.3.0" />
<PackageReference Include="System.Linq.Queryable" Version="4.3.0" />

Using statements:

using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.EntityFrameworkCore;

Note that FromSqlRaw is available, but ExecuteSqlRaw, ExecuteSqlRawAsync , etc are not.

EDIT: I added a using Microsoft.EntityFrameworkCore and the error has changed to:

'DbSet' does not contain a definition for 'ExecuteSqlRaw' and the best extension method overload 'RelationalDatabaseFacadeExtensions.ExecuteSqlRaw(DatabaseFacade, string, params object[])' requires a receiver of type 'DatabaseFacade'
