DbContext could not be found

In this Azure tutorial, we will discuss fixing the error, The Type Or Namespace DbContext Could Not Be Found, which I got while working with the  Azure Function Project.

DbContext could not be found

I recently worked with one Azure Function Project where I had to implement the Entity Frame Work to interact with the SQL Database using Visual Studio 2019. I have created one Data context class which was supposed to inherit from the DbContext. But while implementing that, I got the error The Type Or Namespace DbContext Could Not Be Found.

One point to note down here is I had already installed the EntityFramework NuGet Package but still I got the above error.

Below is my DataContext class code

using System;
using System.Collections.Generic;
using System.Text;

namespace MyAzurefunctionEF
{
    class UserDataContext: DbContext
    {
      //Implementation logic
    }
}

I got the Error. You can see it below

applicationdbcontext could not be found

The exact error message was as below

CS0246 The type or namespace name ‘DbContext’ could not be found(are you missing directive or an assembly reference?)
