How to debug a script that is executed by ScriptExecutor?

[Kilian-E]

Hello,

I use the https://github.com/scriptcs-contrib/scriptcs-mef/ module. This module calls the ExecuteScript method of the ScriptExecutor class in order to compile/execute cs-scripts. So far so good.
When I pass "-debug" as argument to the scriptArgs parameter of the method, I assume the script engine to create an assembly that can be debugged. But it seems this assumption is wrong:
In the ReturnValue of the scriptResult (CommonScriptEngine → Execute()), I can see, that the created assembly has the DebuggableAttribute in the CustomAttributes-List. But its constructor parameter ist 263 which is not a valid value according to the microsoft docs.

Is it possible to compile the assembly in a way, that it can be debugged?

Best regards
Kilian
