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

Answer 1

1. Ensure the BuildAction of your App.xaml is set to "ApplicationDefinition"
2. Delete the "obj" folder in the project, rebuild.
3. If the problem persist, get rid of the "_" character in your namespace.

Answer 2

I had the same build error but the build action was already set to Page. Trying Build Action set to ApplicationDefinition (error: there can only one instance of that), and setting it back to Page, fixed the build error. Sounds like black magic, but it worked for me.

Answer 3

After successful builds, when the error occurs, close VS, delete the hidden .vs folder in your project (this clears intellisense). Open VS, the error is gone.

Answer 4

This is the same question and answer here: The name 'InitializeComponent' does not exist in the current context

You might get this error when you import a class from another project, or change the path of the xaml file, or the namespace of either the xaml or behind .cs file.

One: It might have a namespace that is not the same as what you have in you new project

namespace TrainerB.MVC.Forms
{
     public partial class AboutDeveloper : ContentPage
     {
          public AboutDeveloper()
          {
               InitializeComponent();
          }
     }
}

As you can see the name space in the imported file begins with the old project name: "TrainerB", but your new project might have a different name, so just change it to the correct new project name, in both the .xaml file and the behind .cs file.

Two:

change the properties of the .xaml file to:

Build Action: Embedded Resource

Custom Tool: MSBuild:UpdateDesignTimeXaml

Answer 5

My solution was to set the Build Action property of Package.appxmanifest to AppxManifest. :)

Answer 6

This worked for me, Try Ctrl+S on the pages that give you this error. The error came about, when my visual studio crashed(restarted). The pages I was working on(before the restart) didnt failed to build. Which lead me to think the didnt save correctly. Hence, Ctrl+S. That solved my issue.
