Detect whether the assembly was built for .NET Compact Framework

Question

Having a .NET assembly, how can I detect whether it was built for .NET CF or a full framework?

Answer 1

It's quite simple:

public enum AssemblyType
{
    CompactFramework,
    FullFramework,
    NativeBinary
}

public AssemblyType GetAssemblyType(string pathToAssembly)
{
    try
    {
        Assembly asm = Assembly.LoadFrom(pathToAssembly);
        var mscorlib = asm.GetReferencedAssemblies().FirstOrDefault(a => string.Compare(a.Name, "mscorlib", true) == 0);
        ulong token = BitConverter.ToUInt64(mscorlib.GetPublicKeyToken(), 0);

        switch (token)
        {
            case 0xac22333d05b89d96:
                return AssemblyType.CompactFramework;
            case 0x89e03419565c7ab7:
                return AssemblyType.FullFramework;
            default:
                throw new NotSupportedException();
        }
    }
    catch (BadImageFormatException)
    {
        return AssemblyType.NativeBinary;
    }
}

I rather use CCI or Cecil to parse its metadata and check out which set of references it depends on.
