Its possible ?

I don't understand why this code works fine:

<Style x:Key="MyStyle" TargetType="{x:Type Canvas}">
<Setter Property="Width" Value="125" />
<Setter Property="Height" Value="55" />
<Setter Property="Background" Value="White" />
</Style>

But this one its wrong:

<Style x:Key="MyStyle">
<Style.Resources>
<Style TargetType="Canvas">
<Setter Property="Width" Value="125" />
<Setter Property="Height" Value="55" />
<Setter Property="Background" Value="White" />
</Style>
</Style.Resources>
</Style>

What I have tried:

The case is I want to inject several types in this last MyStyle, such as textboxes, ellipses, etc..

I explained myself well?

If you want the same style to work with multiple types, you actually need to create a style that targets a base type of those controls. You don't have to constrain yourself to the most derived type. For instance, you could define a style for all Panel types (Canvas, etc), like this:

C#

<Style x:Key="PanelStyle" TargetType="{x:Type Panel}">
  <Setter Property="Width" Value="125" />
  <Setter Property="Height" Value="55" />
</Style>
