Adding drawables to an ImageView

I am having an issue with Mono for Android and adding drawables as background images or image resources in an ImageView. I have a file in my drawable folder called LogoLarge.png, which I want to display. Its Build Action is set to AndroidResource. So I try this:

<ImageView 
  android:id="@+id/Logo"
  android:src="@drawable/LogoLarge"
  android:layout_height="wrap_content" 
  android:layout_width="wrap_content" 
  />

The LogoLarge resource is referenced in Resource.Designer.cs. Building the project works fine. When I try to deploy to the emulator, I get the following in the build output:

C:\Program Files (x86)\MSBuild\Novell\mandroid.exe -v --nosign --sdk-dir="C:\Android" --builddir="C:\Users\Vegard\Documents\Visual Studio 2010\Projects\HelloAndroid\HelloWorld2\obj\Debug\android" --framework-dir="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v2.2" --framework-dir="C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0" -S="C:\Users\Vegard\Documents\Visual Studio 2010\Projects\HelloAndroid\HelloWorld2\obj\Debug\res" --package="HelloWorld2.HelloWorld2"   --nolink --abi="armeabi" --java-sdk-dir="C:\Program Files\Java\jdk1.6.0_26" --debug --manifest-template="C:\Users\Vegard\Documents\Visual Studio 2010\Projects\HelloAndroid\HelloWorld2\Properties\AndroidManifest.xml" --sdk-platform="8" "C:\Users\Vegard\Documents\Visual Studio 2010\Projects\HelloAndroid\HelloWorld2\bin\Debug\HelloWorld2.dll" "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v2.2\Mono.Android.dll" "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0\mscorlib.dll" "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0\System.Core.dll" "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0\System.dll" "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0\System.Xml.dll" "C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\MonoAndroid\v1.0\System.Xml.Linq.dll"

If I remove the android:src property from the XML file, and put this in my Activity1.cs file, it works:

ImageView i = FindViewById<ImageView>(Resource.Id.Logo);
i.SetImageResource(Resource.Drawable.LogoLarge);

The same issue also occurs when trying to set a background image for any view using android:background="@drawable/SomeBackground" in XML, but works fine when doing it programmatically.

What is happening here. Is this a bug in MonoDroid?

I think that your LogoLarge must be logolarge , because you only can use lower case letters in the drawables.
