Can we have one .exe calling a .dll with XAML and Prism (for MVVM)? - prism

Question

My question is this: How can I call a library project (DLL) that contains all my XAML (Views) and ViewModel classes from another project that is meant to only run as an "EXE"? (I want to use Prism 7 for MVVM purposes).
My intent is to have one project whose only purpose is to create an .EXE. This EXE will load the assembly where the actual WPF views and the viewmodels reside.
Ideally, I'd like to have App.xaml in the EXE project... But I want to have my Bootstrapper in the Assembly project... Is this possible with Prism 7?
I want to have an App.xaml in "Company.Product.Application" project (which produces an EXE):
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Company.Product.Application"
xmlns:Presentation="clr-namespace:Company.Product.Presentation;assembly=Product.Presentation"
DispatcherUnhandledException="Application_DispatcherUnhandledException"
xmlns:prism="http://prismlibrary.com/">
<Application.Resources>
<ResourceDictionary>
<Presentation:AppBootstrapper x:Key="Bootstrapper" />
</ResourceDictionary>
</Application.Resources>
Then from my Bootstrapper, I want to load my IoC and create my views and viewmodels.
I have been able to accomplish this with Caliburn.Micro... The idea here is that "Company.Product.Presentation" DLL can be tested out without having to create an EXE in itself. I could add the reference to "Presentation" in my test project (NUnit) and test it independently. The EXE is just a project that calls on "Company.Product.Presentation" DLL to actually generate Graphical User Interface goodness.
I appreciate any insight you may have in regards to this question. Thanks!

Sure, just reference the dll with the bootstrapper from the exe and put something like this in App.xaml.cs:
protected override void Onstartup(StartupEventArgs e)
{
base.OnStartup(e);
var bootstrapper = new Company.Product.Presentation.Bootstrapper();
bootstrapper.Run();
}
