Steps to reproduce

1. Project Setup

• Create a new MVC Project with Authentication enabled. Choose Individual Accounts for type.
• Scaffold the Register.cshtml page for a custom User class that inherits from IdentityUser by using the steps described in the official documentation for scaffolding Account pages.
• Make sure this User class has additional fields like First Name and Last Name
• Open the Register.cshtml page and add the additional fields for First Name and Last Name
• Open Register.cshtml.cs and expand Input to include the new fields.
• Set the First Name and Last Name fields in the custom User class in OnPostAsync in Register.cshtml.cs

2. Debugger Setup

• Create the launch.json file in .vscode
• Use the default .NET Core Launch (Web) setup
• Change the "program" path to the .dll file.

Debugging

• Debug the program, the View Index cannot be found.
• Stop the Debugger and update program.cs by adding RazorRuntimeCompilation to the Services (needs NuGet Package)
• Debug the Program again. Views work now. Navigate to the Register page.
• The View is still the standard Register View and not the scaffolded version with the additional fields.
• Stop the debugger and open the terminal. Type dotnet run and press enter
• Navigate to the Register page and notice it now displays the correct View with the fields for First Name and Last Name.

Expected behavior

• Using both dotnet run and the Debugger should show the same results in Views

Actual behavior

• Running the app with the Debugger shows different Views. The first image is using the Debugger. The second is when using dotnet run

Additional context

• Similar issues occur when trying to use .resx files for translations. Using a ViewLocalizer in a Razor page will only display the Values when using dotnet run. With the debugger, it simply displays the Keys as the .resx files appear to not be loaded / compiled when using the debugger.
• This version of VS Code runs in a container, but it has full access to all files outside the container and the problem persists.
