Disable the default constructor on a Database-First workflow

You can modify the template to provide the constructor you want.

• Open the *.Context.tt file
• Go to line ~59

• Change this code.

  public <#=code.Escape(container)#>()
      : base("name=<#=container.Name#>")
  

• Into the default constructor you want, for example.

  public <#=code.Escape(container)#>(string nameOrConnectionString)
      : base(nameOrConnectionString)
  

• Save

You can inherit the DbContext created by the template, define your own constructor, and use the inherited DbContext instead of the one generated by the template.

public class MyModifiedDbContext : TheTemplateGeneratedDbContext
{
   public MyModifiedDbContext() 
   {
       // define your own constructor
   }
}

Or make it private to avoid its use, so you get the error at compile time

public class MyModifiedDbContext : TheTemplateGeneratedDbContext
{
   private MyModifiedDbContext() 
   // ...
}

Use MyModifiedDbContext instead of TheTemplateGeneratedDbContext
