it seems it is not possible to bind a command on a modernbutton, because nothing happend.
if possible - what do i wrong?
if not possible - why not? :/
            <mui:ModernButton EllipseDiameter="32" IconWidth="20" IconHeight="20" IconData="{StaticResource IconAdd}">
                    <CommandBinding Command="ApplicationCommands.New" CanExecute="New_CanExecute" Executed="New_Executed" />

this works just fine for me:
<mui:ModernButton Command="{Binding SearchCommand}"
                               ToolTip="search projects" />

Works fine for me... just didn't use the same specific command nowhere, but I use a lot "NavigationCommands.GoToPage" and some others

I experienced something similar: a MVVM Light RelayCommand with this body works fine:
toggleIsEditingNumberCommand = new RelayCommand(() => { IsEditingNumber = !IsEditingNumber; });
but when adding some more lines to the lambda body it just stops to work. Don't know if this is somehow related to MVVM Light or something non-async in the lambda body (like it is in Silverlight, whichs won't even compile AFAIR when e.g. calling a service synchronuously). Could you please specify your MVVM-framework?

I remember dealing with this in mvvmlight. I just stopped using lambdas as my command method, and instead just always had my command call a method.

for example:
public RelayCommand MyCommand { get; private set;}
private void ExecuteMyCommand()
    // do stuff. 

MyCommand = new RelayCommand(() => ExecuteMyCommand());
To, this is more readable anyhow.
