System.IO.FileNotFoundException: Could not load file or assembly 'ConcurrencyLab.ParallelChecker.Core, Version=2.6.0.0

[MalcolmEllis]

Using v 2.6 with VS2022 17.4.1, Windows 10 Pro 21H2

I suspect this is the same issue as this: https://community.sonarsource.com/t/ad0001-errors-system-io-filenotfoundexception-could-not-load-file-or-assembly-sonaranalyzer-cfg/71341/15 and also Roslynator 2022: dotnet/roslynator#1001. As I reported there, based on the Sonar issue thread, it seems to be tied to whether the VS setting (text editor/c#/advanced) 'run code analysis in separate process' is on, and that the last update of VS 2022 turned that 'on' by default. Switching that off stops the error. Sonar and Roslynator are fixed, not sure why this one cropped up days later but hopefully there's enough info in those cases to figure out a fix.

Stack trace starts like this:
AD0001 Analyzer 'ParallelChecker.ParallelAnalyzer' threw an exception of type 'System.TypeInitializationException' with message 'The type initializer for 'ParallelChecker.ParallelAnalyzer' threw an exception.'.
System.TypeInitializationException: The type initializer for 'ParallelChecker.ParallelAnalyzer' threw an exception.

Thank you very much. Unfortunately, this is a problem with the latest VS 2022 version 17.4.2. I am working on a fix, by redesigning at the same time the analysis process, cf. branch https://github.com/blaeser/parallelchecker/tree/luc%2Fnew_release. I hope to have a new release soon.

This should be now fixed with the latest 2.7.0 release of Parallel Checker.
