Postsharp Error after updating newtonsoft

Question

I have a .net framework solution, that uses postsharp version 4.2.21.0.

I have a demand to upgrade our newtonsoft.json package from 11.0.2 to 13.0.1. After this upgrade, solution became unable to build, because os this post sharp error

When I downgrade newtonsoft.json back to 11.0.2, solution builds fine.

Is it possible to update this newtonsoft.json withou geting the postsharp error?

This is certainly a bug in PostSharp 4.2, released in 2015, but it is currently unsupported. Please update to a supported version.
