    @DarshanJS - Post your app.xaml and app.xaml.cs (or the relevant bits thereof), plus an example of where you consume one of the global styles.

    No reason they shouldn't be working. I think its lesson 104 on my series that talks about styles - if it helps.

    Code in app.xaml

        <Application.Resources>
            <ResourceDictionary>
                <Style x:Key="MyTitleLabel" TargetType="Label" >
                    <Setter Property="FontSize" >
                        <Setter.Value>

                            <OnIdiom x:TypeArguments="x:Double">
                                <OnIdiom.Phone>
                                    <OnPlatform x:TypeArguments="x:Double" iOS="14" Android="15"  />
                                </OnIdiom.Phone>
                                <OnIdiom.Tablet>
                                    <OnPlatform x:TypeArguments="x:Double" iOS="21" Android="21"  />
                                </OnIdiom.Tablet>
                            </OnIdiom>
                        </Setter.Value>
                    </Setter>
                    <Setter Property="TextColor" Value="#000000" />
                    <Setter Property="FontAttributes" Value="None" />

                </Style>
        </ResourceDictionary>
     </Application.Resources>

    usage of styles in other pages for label

    <Label x:Name="lblmessage" Margin="20,20,0,0"  IsVisible="False" Grid.Row="1" Text="Sorry, No results found"  HorizontalOptions="CenterAndExpand"  Style="{StaticResource MyTitleLabel}"/>

    @DarshanJS - I do mine in C# currently, rather than XAML, but from a quick look nothing looks obviously wrong in what you posted above. Is Intellisense highlighting anything, or are there any warnings when you build? Is NuGet warning about any consolidation being possible?

    I hate to ask this, but since upgrading to VS2017, have you deleted your bin and obj folders? Also, if you check your version control history, has anything been changed since the upgrade?

    I've never used OnIdiom in my styles. Just for a test, do more vanilla styles work? Just really simple ones where you set color and size and nothing else. I'm just looking to narrow down if its all styles, or just OnIdiom in styles.

    Yes it is highlighting for "OnIdiom.Phone" saying that "The attachable property 'Phone' was not found in the type on OnIdiom

    have you deleted your bin and obj folders?
    No, i didn't deleted anything and also we are maintaining projects in TFS

    Sure i will check by removing OnIdiom and try with simple styles

    Like I said, I don't use XAML for this, so I could be completely wrong, but should the '.' in OnIdiom.Phone be a space?

    No it should be OnIdiom.Phone
    Thing is if i define same style code in every page under ResourceDictionary it is working properly, only it is not fetching from App.Xaml i am facing strange issue.

    @ClintStLaurent :

    Thanks guys you both saved my day. Sometimes Xamarin will give crazy issues (other than this issue) . Thanks for everything.

    This code is simple and worked for me

            <Style x:Key="MyTitleLabel" TargetType="Label">
                        <Setter Property="FontSize">
                            <Setter.Value>
                                <OnPlatform x:TypeArguments="x:Double" >
                                    <On Platform="Android" >
                                        <OnIdiom x:TypeArguments="x:Double" Tablet="25" Phone="25" />
                                    </On>
                                    <On Platform="iOS" >
                                        <OnIdiom x:TypeArguments="x:Double" Tablet="25" Phone="25" />
                                    </On>
                                </OnPlatform>
                            </Setter.Value>
                        </Setter>
                    </Style>
