Type loading by Assembly.LoadFrom is not the same

I'm creating type by name to put them to DI container. For any reason the DI container fails to register/resolve types created this way:

Type interfaceTypeFromAssembly = Assembly.LoadFrom(InterfacesAssemblyPath).GetTypes().First(t => t.Name == interfaceName);
Type implementorTypeFromAssembly = Assembly.LoadFrom(ApplicationAssemblyPath).GetTypes().First(t => t.Name == implementorClassName);

I compared types and found that:

Type implClassType= typeof(ImplClass);
Type implClassType2= typeof(ImplClass);
bool res = implClassType == implClassType2; // True

res = implClassType == implementorTypeFromAssembly; // False

The last line gives False although types have the same GUID.

What's the reason of such a behavior?
