why is my wpf application starting in web browser?

I created a wpf application which have a single window which is getting started on a web browser. I need to run it as a standalone application.

Code goes below.

<Application x:Class="WPFTESTER.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    StartupUri="Page1.xaml">
    <Application.Resources>

    </Application.Resources>
</Application>



<Window x:Class="WPFTESTER.MyWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
    <Grid>
        <telerik:RadGridView x:Name="testGrid" AutoGenerateColumns="False">
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"/>
                <telerik:GridViewDataColumn IsReadOnly="True">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <telerik:RadButton Click="RadButton_Click" Content="Button1"/>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>
                <telerik:GridViewDataColumn IsReadOnly="True">
                    <telerik:GridViewDataColumn.CellTemplate>
                        <DataTemplate>
                            <telerik:RadButton Click="RadButton_Click" Content="Button2"/>
                        </DataTemplate>
                    </telerik:GridViewDataColumn.CellTemplate>
                </telerik:GridViewDataColumn>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>
    </Grid>
</Window>

Because you create WpfBrowserApplication. Create Wpf Application and everything will be fine

In the Application block you've got

StartupUri="Page1.xaml">

I'm guessing you need to change that to be the name of you main xaml page.

Also check the project type - should not be a 'browser app'
