I'm trying to create a button that has an image in it and no border - just like the Firefox toolbar buttons before you hover over them and see the full button.

I've tried setting the BorderBrush to Transparent, BorderThickness to 0, and also tried BorderBrush="{x:Null}", but you can still see the outline of the button.

Fantastic! Every other solution I've found is extremely convoluted and involves overriding all styling of the button.
Unfortunately, it disables the effect of setting HorizontalContentAlignment to Stretch.
@Cœur the questions specified WPF not Silverlight
This is turning my button into a toggle button. When I click the button it stays selected until I click another button. How would I stop it from acting like that?
I'd upvote this twice if I could. Saved me a lot of code to get the look I want.

You may have to change the button template, this will give you a button with no frame what so ever, but also without any press or disabled effect:

    <Style x:Key="TransparentStyle" TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Background="Transparent">
                        <ContentPresenter/>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

And the button:

<Button Style="{StaticResource TransparentStyle}"/>

I don't know why other solutions seems to work at other people. This solution is the only one which can work because the ContentPresenter Border line is also removed! Good work!
I tried several other solutions, this is the only one works. btw, for newbies, the <style></style> code should be in the header of your xaml like in <Window><Window.Resource><Style>....
also, there is a typo in the answer: <Button Style="{StaticResource TransparentButton}"/> should be <Button Style="{StaticResource TransparentStyle}"/>
Worked for me as well, great solution!
Why there is empty <ContentPresenter/> ? What is it for?

What you have to do is something like this:

<Button Name="MyFlatImageButton"
        Background="Transparent"
        BorderBrush="Transparent"
        BorderThickness="0" 
        Padding="-4">
   <Image Source="MyImage.png"/>
</Button>

Hope this is what you were looking for.

Edit: Sorry, forgot to mention that if you want to see the button-border when you hover over the image, all you have to do is skip the Padding="-4".

This works, and this is very nice idea in some cases
This works perfectly when you want to stretch an image inside a button. Removing the padding lets the image occupy the full button dimensions.
To remove only the border, BorderThickness="0" is enough

I don't know why others haven't pointed out that this question is duplicated with this one with accepted answer.

I quote here the solution: You need to override the ControlTemplate of the Button:

<Button Content="save" Name="btnSaveEditedText" 
                Background="Transparent" 
                Foreground="White" 
                FontFamily="Tw Cen MT Condensed" 
                FontSize="30" 
                Margin="-280,0,0,10"
                Width="60"
                BorderBrush="Transparent"
                BorderThickness="0">
    <Button.Template>
        <ControlTemplate TargetType="Button">
             <ContentPresenter Content="{TemplateBinding Content}"/>
        </ControlTemplate>
    </Button.Template>  
</Button>

If you don't put any content inside the button it will not respond to clicks. You can fix that by wrapping that ContentPresenter in a Border with a transparent background. That way you can make a blank/transparent button of any size to place over an image.

You can use Hyperlink instead of Button, like this:

        <TextBlock>
            <Hyperlink TextDecorations="{x:Null}">
            <Image Width="16"
                   Height="16"
                   Margin="3"
                   Source="/YourProjectName;component/Images/close-small.png" />
            </Hyperlink>
        </TextBlock>

I like this solution. It's a nice trick, gives you a hand cursor on hover and doesn't require to use a custom style.

You may already know that putting your Button inside of a ToolBar gives you this behavior, but if you want something that will work across ALL current themes with any sort of predictability, you'll need to create a new ControlTemplate.

Prashant's solution does not work with a Button not in a toolbar when the Button has focus. It also doesn't work 100% with the default theme in XP -- you can still see faint gray borders when your container Background is white.

Why don't you set both Background & BorderBrush by same brush

 <Style TargetType="{x:Type Button}" >
        <Setter Property="Background" Value="{StaticResource marginBackGround}"></Setter>
        <Setter Property="BorderBrush" Value="{StaticResource marginBackGround}"></Setter>            
 </Style>

<LinearGradientBrush  x:Key="marginBackGround" EndPoint=".5,1" StartPoint="0.5,0">
    <GradientStop Color="#EE82EE" Offset="0"/>
    <GradientStop Color="#7B30B6" Offset="0.5"/>
    <GradientStop Color="#510088" Offset="0.5"/>
    <GradientStop Color="#76209B" Offset="0.9"/>
    <GradientStop Color="#C750B9" Offset="1"/>
</LinearGradientBrush>
