'Unhandled exception. System.MissingMethodException' on .NET7 project with preview language

[Stijnwingens]

Describe the bug
Even though I'm using the language-version: Preview option, the Stryker.NET execution fails (System.MissingMethodException). The error message suggests that the language version is not read (or used by me) correctly?

Logs

Logs found in attachments.

Expected behavior
No exception.

Desktop (please complete the following information):

• OS: Windows 10
• Visual Studio Solution
• .NET7 (preview language version)
• Stryker Version 3.12.0

Additional context
First time using Stryker.NET. Using the following conf file (stryker-config.yml):

  stryker-config:
    language-version: Preview
    target-framework: net7.0
    
    mutation-level: Complete
    reporter: html

run with dotnet stryker -f stryker-config.yml

Sorry, seems like a duplicate of #2776. Thought it had to do with preview language. Can probably be closed as duplicate.

@Stijnwingens could you post the exception? The logs don't contain it so I can't confirm that it's the same issue.

Going to 3.11 fixed the issue for me so I assume it's the same. The exception was:

Unhandled exception. System.MissingMethodException: Method not found: 'System.Collections.Generic.IEnumerator`1<Microsoft.CodeAnalysis.NodeStateEntry`1<System.ValueTuple`2<System.__Canon,System.__Canon>>> Microsoft.CodeAnalysis.NodeStateTable`1.GetEnumerator()'.
