Running the RevitTestFrameWork with 2023

[talisman]

Hi ,
I want to use this Framework for testing my revit plugins , no dynamo involved at this point .
I git cloned this repo, replaced the Revit references with DLLs from Revit 2023 and compiled it successfully.
I created a solution with two projects - one for my production code the other for testing . The testing one references the production as well as the RTFRevit.dll and the RevitTestFrameworkTypes.dll . Both the production and the test projects compiles fine.
Once I run the GUI version I get the list of Revit Versions installed on my machine which indicated that I am in the right direction.
Once I choose the Dll containing the test, specify the working folder and the results file, select (test or multiple tests) and click run - nothing happens .
When I run the Console version with all the required parameters I get output of the tests discoverd and the models and an error :

...
Attempting to resolve referenced assembly: RevitTestFrameworkTypes, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

Unable to cast object of type 'System.Xml.XmlComment' to type 'System.Xml.XmlElement'.

I get the same errors when trying to run against the SampleTests that ship with the repo .
Any idea where this issue comes from ?
Thanks
