分享2个应用：Session State ASP.Net MVC反序列化错误

Question

I'm hosting two applications under one website on IIS. The main application creates a session state when the user logs in. I am able to share the session between the two applications, but when I try to access the specific session variable I get a deserialization error seen below. On my second application, I load the dll (in Global.asax during start up) that it claims is missing. I even confirm that it has been loaded before accessing the session and it still throws an error. The library that's loaded is from the same directory and has the same exact assembly string that it's complaining about.

Perhaps it's loading it to a different domain of the application? Does anybody know why it's still not working? Any suggestions would be great.

(Unable to find binary)

(Confirmed that the DLL is properly loaded upon startup for the second app)

Answer 1

This looks like a dependency issue, yes the file is there, but maybe some other file it depends on is not there. The error message could be a bit misleading

Answer 2

This is a issue with type-based serializer, please refer to this post here ArrayTypeMismatch Exception in Session
