title: Unable to make changes to specific files in .NET Core 3.1 scaffolded identity
body: <p>I have scaffolded the Identity files in my .NET Core 3.1 MVC project and I can edit most of the files in the <code>Areas/Identity/Pages/Account</code> directory but any changes I make to the <code>Register.cshtml.cs</code> and <code>RegisterConfirmation.cshtml.cs</code> are not reflected when debugging in VS for Mac. Also in VS for Mac I can't edit the <code>RegisterConfirmation.cshtml</code> or <code>Register.cshtml</code> files, however they exist in the <code>Account</code> directory when I navigate to it outside of VS. Is there a reason why these specific files seem to have some sort of restriction?</p>
