Xaml g.cs file

When creating a new application, the automatically generated App. The main thing to notice here is the StartupUri property. This is actually the part that instructs which Window or Page to start up when the application is launched. In this case, MainWindow. In some situations, you want more control over how and when the first window is displayed. In that case, you can remove the StartupUri property and value and then do it all from Code-Behind instead.

I had pretty much the same issues, although I was not updating an old project, mine was completely new. I solved the issues with reloading the project, sometimes some small actions can change a lot Could you try to delete the bin folders and the obj folders and rebuild it? I understand how to solve this - it happens if an item on the page contentpage or contentview has an object that is unresolved.

In some cases you will see this happen when you use Lists:. They are defined in the clr-namespace:System. This kills the file generation. The content you requested has been removed.

Ask a question. Forms, for example ContentPage. The second namespace declaration defines a prefix of x. However, these elements and attributes are slightly different depending on the year embedded in the URI. Forms supports the XAML specification, but not all of it. The local namespace declaration allows you to access other classes from the.

NET Standard library project. At the end of that first tag, the x prefix is used for an attribute named Class. The x:Class attribute specifies a fully qualified. This is the only new class defined in the XAML file.

Everything else that appears in the XAML file is instead simply instantiated from existing classes and initialized. The MainPage class derives from ContentPage , but notice the partial class definition.

This suggests that there should be another partial class definition for MainPage , but where is it? And what is that InitializeComponent method? This is the other partial class definition of MainPage that contains the definition of the InitializeComponent method called from the MainPage constructor.

These two partial MainPage class definitions can then be compiled together. At runtime, code in the particular platform project calls a LoadApplication method, passing to it a new instance of the App class in the.

NET Standard library. The App class constructor instantiates MainPage. LoadFromXaml initializes all the objects defined in the XAML file, connects them all together in parent-child relationships, attaches event handlers defined in code to events set in the XAML file, and sets the resultant tree of objects as the content of the page.

When you compile and run this program, the Label element appears in the center of the page as the XAML suggests:. Give the page a name, for example, HelloXamlPage :. Two files are added to the project, HelloXamlPage. Edit the HelloXamlPage.

Content :. The ContentPage. Content tags are part of the unique syntax of XAML. At first, they might appear to be invalid XML, but they are legal. The period is not a special character in XML. Content tags are called property element tags. Content is a property of ContentPage , and is generally set to a single view or a layout with child views.

Normally properties become attributes in XAML, but it would be hard to set a Content attribute to a complex object. For that reason, the property is expressed as an XML element consisting of the class name and the property name separated by a period. Name and my project had a namespace in it, eee. I removed ViewModels and Commands, but forgot to remove the [assembly:] attributes, so it was looking for them when I rebuilt.

Removed the offending lines, et voila. This give's me the error in g. So it seems this issue happens when the namespace name is the same as the class name. I have to change them to below which caused the error gone.

The compiler was keep on throwing error. Give proper name or remove that empty string solves the error for me. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?
