Dependency injection is possible in asp.net core razor pages as well.

You can do constructor injection in your page model class.

public class LoginModel : PageModel
{
    private IFileSystem fileSystem;
    public LoginModel(IFileSystem fileSystem)
    {
        this.fileSystem = fileSystem;
    }

    [BindProperty]
    public string EmailAddress { get; set; }

    public async Task OnPostRefresh()
    {
       // now you can use this.fileSystem
       //to do : return something
    }
}

Dependency injection is also possible in the pages :). Simply use the inject directive.

@model YourNameSpace.LoginModel 
@inject IFileSystem FileSystem;
My page
// Use FileSystem now
