If you want to use Entity Framework you should consider to use Database First approach.

Other simple and fast way to import a Sql Server scheme to a class in VS is this:

1. Make a select as json query:

   SELECT * FROM Approval 
   FOR JSON AUTO
   

2. Copy one row from the result in your clipboard:

   [
     {"Id":1, "FormId":10, "DesignationId":100, "CreatedOn":"2000-01-01T00:00:00"},
     {"Id":2, "FormId":20, "DesignationId":200, "CreatedOn":"2000-01-01T00:00:00"}
   ]
   

3. Paste in Visual Studio: Edit > Paste Special > Paste JSON As Classes
