Windows App Certification Kit Fails with error - All types referenced in metadata files must be discoverable

Question

I created a Windows Runtime Component DLL with the following class:

namespace WindowsRuntimeComponent1
{
    public ref class Class1 sealed
    {
    public:
        Class1();
        static Platform::Type^ GetTypeTest();
    };
}

When I consume this from a C# Windows Store application, the application fails the WACK with errors:

The type System.Type referenced by type WindowsRuntimeComponent1.__IClass1Statics in file C:\Program Files\WindowsApps\8c839635-2b37-41ba-a6eb-8e01fdfac0d3_1.0.0.2_x86__ze744fdnb0cr8\WindowsRuntimeComponent1.winmd was not found. All types referenced in metadata files must be discoverable.
The type System.Type referenced by type WindowsRuntimeComponent1.Class1 in file C:\Program Files\WindowsApps\8c839635-2b37-41ba-a6eb-8e01fdfac0d3_1.0.0.2_x86__ze744fdnb0cr8\WindowsRuntimeComponent1.winmd was not found. All types referenced in metadata files must be discoverable.

Answer 1

Hi Ike,

Looks like your RuntimeComponent cannot be found on the package file, I would like to know how you create this, because Windows Runtime Component does not a DLL, it create a .winmd file instead.

Answer 2

Hi Ike,

Any update? If your code is as simple as you wrote in the question, you may need share CPP code with us to have a better analysis.  "All types referenced in metadata files must be discoverable." looks like some types are not discoverable in your app, you may need to validate this.

What more code do you need?  I put the code for the component right in the original post:

namespace WindowsRuntimeComponent1
{
    public ref class Class1 sealed
    {
    public:
        Class1();
        static Platform::Type^ GetTypeTest();
    };
}
