WPF MahApps.Metro Embedded Dll Resource not working - wpf

Question

my problem is that the embedded dlls of MahApps.Metro and MahApps.Metro.IconPacks are not working fine.
Used the Visual Studio debugger to check if they are getting loaded and it worked fine. If it could not load them the program would throw a xaml exception.
But for some reason the ResourceDictionaries which are merged are not working in runtime.
Should look like this
But looks like this
(As you can see the text color is different and it is missing the icon on the right side => does not load the styles.)
It looks like the first picture if both Dll's are provided in the directory of the program.

Answer 1

This code works for me: (add all libraries as Embedded Resource and set startup object to this class)
public class Program
{
private static Assembly ExecutingAssembly = Assembly.GetExecutingAssembly();
private static string[] EmbeddedLibraries =
ExecutingAssembly.GetManifestResourceNames().Where(x => x.EndsWith(".dll")).ToArray();
[STAThreadAttribute]
public static void Main()
{
AppDomain.CurrentDomain.AssemblyResolve += CurrentDomain_AssemblyResolve;
App.Main();
}
private static Assembly CurrentDomain_AssemblyResolve(object sender, ResolveEventArgs args)
{
// Get assembly name
var assemblyName = new AssemblyName(args.Name).Name + ".dll";
// Get resource name
var resourceName = EmbeddedLibraries.FirstOrDefault(x => x.EndsWith(assemblyName));
if (resourceName == null)
{
return null;
}
// Load assembly from resource
using (var stream = ExecutingAssembly.GetManifestResourceStream(resourceName))
{
var bytes = new byte[stream.Length];
stream.Read(bytes, 0, bytes.Length);
return Assembly.Load(bytes);
}
}
}

Answer 2

The project file portion was cut off previous answer.
Add this to project file
<!--Then add this is project file.-->
<Target Name="EmbedReferencedAssemblies" AfterTargets="ResolveAssemblyReferences">
<ItemGroup>
<!-- get list of assemblies marked as CopyToLocal -->
<AssembliesToEmbed Include="#(ReferenceCopyLocalPaths)" Condition="'%(Extension)' == '.dll'" />
<!-- add these assemblies to the list of embedded resources -->
<EmbeddedResource Include="#(AssembliesToEmbed)">
<LogicalName>%(AssembliesToEmbed.DestinationSubDirectory)%(AssembliesToEmbed.Filename)%(AssembliesToEmbed.Extension)</LogicalName>
</EmbeddedResource>
</ItemGroup>
<Message Importance="high" Text="Embedding: #(AssembliesToEmbed->'%(DestinationSubDirectory)%(Filename)%(Extension)', ', ')" />
</Target>
<!-- no need to copy the assemblies locally anymore -->
<Target Name="_CopyFilesMarkedCopyLocal" />

I had the same issue you described and came across fix that resolves the issue.
public partial class App : Application {
public App() {
AppDomain.CurrentDomain.AssemblyResolve += OnResolveAssembly;
}
private static Assembly OnResolveAssembly(object sender, ResolveEventArgs args) {
var executingAssembly = Assembly.GetExecutingAssembly();
var assemblyName = new AssemblyName(args.Name);
var path = assemblyName.Name + ".dll";
if (assemblyName.CultureInfo.Equals(CultureInfo.InvariantCulture) == false) {
path = String.Format(#"{0}\{1}", assemblyName.CultureInfo, path);
}
using (var stream = executingAssembly.GetManifestResourceStream(path)) {
if (stream == null)
return null;
var assemblyRawBytes = new byte[stream.Length];
stream.Read(assemblyRawBytes, 0, assemblyRawBytes.Length);
return Assembly.Load(assemblyRawBytes);
}
}
}
%(AssembliesToEmbed.DestinationSubDirectory)%(AssembliesToEmbed.Filename)%(AssembliesToEmbed.Extension)
'%(DestinationSubDirectory)%(Filename)%(Extension)',
', ')" />
