ASP.Net Resume Templater

I am working on the Resume Templater.
[Project link]( syntax/projects/razor-project)

The project isn’t updating when you hit save so I copied everything into Visual Studio. I am getting a CS0117 error that my IndexModel Class is missing a definition for ‘FullName’.

I have
public string FullName { get; set; }
and farther down in the OnGet
FullName = “my name”;

The line the error references is in the Index file where the course has you complete this line

Hey there, I'm @Model.FullName !

Can someone please give me an idea of what I have wrong?
