p587 - Exception because <partial name="_Employee" ... not found about cs11dotnet7

[markjprice]

The naming convention for shared files like layouts and partial views is to prefix with underscore. Your problem was caused by you naming your file Employee.cshtml instead of _Employee.cshtml. Instead of removing the _ from the <partial> element name, you should add it to the name of the file. The exception you got tells you one of the paths that you should use to find it: /Pages/Shared/_Employee.cshtml

I have added some improvements for the next edition that I hope will help to avoid your issue in future:

Mark Thank you for responding to my issue so quickly. As you point out, I failed to notice the initial underscore character in the naming of the file created in the shared folder of the Northwind.Razor.Employees project. I’ve followed your advice and restored the code and file names to how they appeared in the 7th edition, and starting the Northwind.Web up does indeed display the employees page as shown in the book without causing the runtime exception I initially experienced. I have also read your comments and clarifications proposed for the next edition and find them both enlightening and useful. Thank you. For me, the issue I raised can acceptably closed now.
