DbSet does not contain a definition for ‘FromSQL’ and no extension method ‘FromSql’ accepting an argument of type ‘DbSet’ could be found.

Hi everyone,

I ran into the following error while attempting to use a custom query with EntityFramework:

DbSet does not contain a definition for ‘FromSQL’ and no extension method ‘FromSql’ accepting an argument of type ‘DbSet’ could be found.

This one’s pretty straight forward:

// Install the following package via nuget
Install-package Microsoft.EntityFrameworkCore.Relational

//Add the following namespace to your file
using Microsoft.EntityFrameworkCore;

Hopefully that’ll solve it for you, but if not there’s a lot a more information in these posts:
