Ошибка cs0103 имя initializecomponent не существует в текущем контексте

Since this seems to be the go-to thread for the problem regarding missing ‘InitializeComponent’, I’ll include my answer here.

I too was having this issue and I’ve tried everything I found here and in all other Forums that Google could find, however none resolved the issue for me. After two hours of trying everything, I finally figured out what was wrong with my setup.

In our project, we are using Metro components from MahApps. The view that was giving me trouble was a view inheriting from MetroWindow, like this:

<Controls:MetroWindow x:Class="ProjectNamespace.MyView"
                      xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
                      ... >

Now, I have defined my static resources as

<Controls:MetroWindow.Resources>
    <prop:Resources x:Key="LocalizedStrings"/>
    ...
</Controls:MetroWindow.Resources>

That’s how I’ve defined Resources in UserControls in all my other views, so that’s what I assumed will work.

That was, however, not the case with Controls:MetroWindow! There I absolutely needed the resource definition as follows:

<Controls:MetroWindow.Resources>
    <ResourceDictionary>
        <prop:Resources x:Key="LocalizedStrings"/>
        ...
    </ResourceDictionary>
</Controls:MetroWindow.Resources>

So my issue, in summary, was a missing <ResourceDictionary> tag. I really don’t know why this produced the ‘InitializeComponent’ error and it weirdly didn’t even produce it on every machine of mine, but that’s how I fixed it. Hope this helps (the remaining 0.001% of people encountering this issue).

I have checked all similar questions on StackOverflow, but none of the answers solved my problem. I simply get the error in title.

Here is my MainVindow.xaml : 

<Window x:Class="CodeFirstMVVM.App.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:cm="clr-namespace:System.ComponentModel;assembly=System"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

        mc:Ignorable="d"
        DataContext="{Binding Source={StaticResource Locator}, Path=CustomerView}"
        Title="MainWindow" Height="500" Width="900">
    <Grid>
        <Canvas>
            <TextBox Height="23" Canvas.Left="131" TextWrapping="Wrap"  Canvas.Top="51" Width="283" Name="txtName" Text="{Binding NameUI}"/>
            <DataGrid x:Name="maingrid" ItemsSource="{Binding Entities, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" SelectedItem="{Binding SelectedEntity}" AutoGenerateColumns="True" Canvas.Left="10" Canvas.Top="265">
                <DataGrid.Columns>
                    <DataGridTextColumn Binding="{Binding Name}" Header="Name" Width="200"></DataGridTextColumn>
                </DataGrid.Columns>
            </DataGrid>
            <DataGrid x:Name="ordergrid" ItemsSource="{Binding ElementName=maingrid, Path=SelectedItem.Orders}" AutoGenerateColumns="True" Canvas.Top="265" Canvas.Left="597">

                    <DataGridTextColumn Binding="{Binding Explanation}" Header="Orders" Width="200"></DataGridTextColumn>
                </DataGrid.Columns>
            </DataGrid>
        </Canvas>

    </Grid>
</Window>

And here is my App.xaml : 

<Application x:Class="CustomerOrder.App.App" 
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
             xmlns:d ="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:mc ="http://schemas.openxmlformats.org/markup-compatibility/2006"
             StartupUri="MainWindow.xaml" 
             mc:Ignorable="d">
    <Application.Resources>
        <vm:ViewModelLocator x:Key="Locator" d:IsDataSource="True" xmlns:vm="clr-namespace:CustomerOrder.App.ViewModel" />
    </Application.Resources>
</Application>

On MainWindow.xaml.cs :

namespace CustomerOrder.App
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }
}

Can you tell me how to fix this? Thanks.

UWP app project showing Intellisense error with a new, from template Xamarin.Forms solution using a Shared project type.

Error CS0103 The name ‘InitializeComponent’ does not exist in the current context App1.UWP
is shown in the errors pane.

The first time I tried to reproduce it, I got a build error and the UWP app project build failed, as described in the forum post. Cleaning and rebuilding resolved the build error but the Intellisense error remained only for the UWP app project.

I then tested again, creating a new template project of the same type. This second time there was no build error, but the Intellisense error was shown for all three app platform projects. At some point, after cleaning and rebuilding and selecting the iOS app project as the startup project, the INtellisense error went away for the iOS app project, but remained for Android and UWP.

I tried closing and re-opening the solutions as well as closing and re-opening the IDE. At some point the Intellisense errors went away. I closed the IDE and re-opened the second solution I created, opened the properties pages to get some info for the bug report, i.e. target frameworks, and the Intellisense errors went away. Not sure after which specific action they disappeared, but it seems to me this was a dance that should not need to be done.

    Hi,

    The error CS0103 (The name ‘InitializeComponent’ does not exist in the current context) has started appearing after doing a build of our Xamarin Forms solution. The build, however, appears to have succeeded in spite of this error message?

    This started happening after adding the first XAML ContentPage to the PCL project. If I remove the XAML ContentPage then the error disappears.

    I’ve tried installing the latest Alpha channel update on both my Windows (Visual Studio) machine and my Mac build host but it hasn’t made any difference.

    Please advise ASAP as we would like to use XAML for our ContentPages but may have to revert to using C# code to build the UI if the XAML approach is not viable.

    Regards,
    Andy
