The name 'InitializeComponent' does not exist in the current context. Cannot get any help on net searches [duplicate]

Answer 1

Here's one other possibility, after exhausting all the above (as well as a few others scattered about the internet): make sure that your Startup object is correctly set to [Project].App in your Project Properties > Application tab.

I had renamed some namespaces, and somewhere in the process VS set the Startup object to "(not set)".

Answer 2

1) In the xaml file, check the x:Name of the main layout. Rename it 2) Compile. It should throw errors 3) Go back to the xaml file and give the same class name as it associated code behind file has (.cs file) Also include the namespace. eg: if namespace is "X" and class name is "Y", x:Name = "X.Y" 4) Compile. It should work.

Answer 3

There are two potential causes of this.

1. The most common is the x:Class doesn't match up with the MainPage.xaml namespace. Make sure that x:Class in MainPage.xaml has the correct namespace.

2. The second most common cause of this problem is that the "Build Action" is not set to "Page" for MainPage.xaml!

Answer 4

In my case, I had set build action of XAML page to Embedded Resource, reverting it to Page fixed the issue.
