"Exception has been thrown by the target of an invocation." following the Sample Translation Service Provider Plug-in example

Question

Hi all, 
 I'm following the Sample Translation Service Provider Plug-in example and I got an "Exception has been thrown by the target of an invocation." error at MyTranslationProviderWinFormsUI.get_TypeName() when I create a new project, add a file and click on "Next". 
 
 I'm using SDL Trados 2017 with Visual Studio 2017. 
 
 I have no idea why, if someone can help me please. 
 Thanks, 
 Matthieu
