Hi running into error while trying the tutorial on Windows 10. I copied the code directly from tutorial and pasted and I get the following error when trying to run. This is my first dive into learning code so any help will be appreciated.

@page
@model IndexModel
@{
ViewData["Title"] = "Home page";
}

The build failed. Fix the build errors and run again.

Can you make sure you edited the Index.cshtml file and not the Index.cshtml.cs file? Sometimes, Windows will hide the file extension.

So in the example below the Index.cshtml file is the first one and not the second.

Let me know if that helps.

That was exactly the issue. Thanks! It works now.

Thanks for confirming. I’ll add something to the tutorial to make that more clear.
