I get "Sequence contains no matching element" exception while trying …

…to load recursively assembly that has c++ project dependencies.

The problem reside in TypeFactory class line 180 or so.
typeDefinition.CustomAttributes.Any(att => att.AttributeType.FullName == typeof(UnsafeValueTypeAttribute).FullName)
returns two attributes - UnsafeValueTypeAttribute and NativeCppClassAttribute
typeDefinition FullName looks like .$ArrayType$$$BY0GC@$$CB_W

typeDefinition.Fields has no fields so trying to get them leads to an exception here:
var arrayType = typeDefinition.Fields.First(field => field.Name == "FixedElementField").FieldType;

Stack trace looks like that:
System.InvalidOperationException
