Description Al Clark [MSFT] 2017-03-02 19:00:48 UTC
=== Overview ===

Error in new template for Forms Content Page Xaml file.  Codebehind is creating an instance of class ContentPageViewModel that doesn't exist.

=== Steps to replicate ===

1. Create a new Forms project.
2. Right-click project and add Forms Content Page Xaml file.

=== Expected result ===

Sample should create instance of class named after the file created.

        public fcp()
            BindingContext = new [NameOfContentPage]ViewModel();

=== Actual result ===

Sample creates instance of ContentPageViewModel resulting in red squigglies and the error:
"The type of namespace name 'ContentPageViewModel' could not be found (are you missing a using directive or an assembly reference?)"

        public fcp()
            BindingContext = new ContentPageViewModel();

Still not fixed. I get it after doing this:

1. In Portable project Add new item...
2. Choose "Forms Content Page Xaml"
3. Click "Add"
4. Open .cs-file and "BindingContext = new ContentPageViewModel();" is still there.
Comment 9 Pierce Boggan [MSFT] 2017-05-05 14:49:14 UTC

This will be fixed in the next stable release of Visual Studio. Thanks so much for the report. :)
