"Stack overflow" error in unity at migration from MO 6 to 7

[FlorianKehrle]

I tried to upgrade my unity project from MagicOnion 6.1.6 to 7.0.2 and did all the steps described in the "Migration guide from v6". Unfortuantely, I allways get an "Stack overflow" error when adding the "MagicOnion.Client.Unity" via package manager or in the "Packages/manifest.json" file.
I also redid it multiple times with cleaned up versions or tried to copy my project structure to a completely new project.

Here is the error I get:

Solved it, with updating all "included" MagicOnion.Client packages via Nuget4Unity - maybe those versions of the dependend packages could be updated in the main MagicOnion.Client package directly (or until thios is done, the "manually update included packages step" added to the MO migration 6to7 description).

Additionally I had to install the "System.IO.Pipeline" package that is needed by YetAnotherHttpHandler.
