    Hello,

    I am creating a UWP app that is just targeting PC and attempting to use the System.Xml.Serialization namespace to serialize and deserialize some content. Whenever I attempt to make a call to this namespace, specifically creating a new serializer, I get the following error:

    Unable to load DLL 'kernel32.dll': The specified module could not be found.

    This was not a problem when using the .NET scripting backend a year ago, but it has since been marked deprecated and we have switched to using the IL2CPP scripting backend. As for a few of my other settings, I am using .NET 4.x Equivalent for the Scripting Runtime Version and .NET 4.x as my API Compatibility Level. The version of Unity I am using is 2018.2.11f1.

    I am not sure if this is something wrong with the IL2CPP build pipeline or if I am doing something incorrect when building the project. Thank you in advance for any help!

    This is a bug in IL2CPP. It only happens in .NET 4.x API compatibility level - you could work around it if you switched to .NET Standard 2.0 (note: not .NET 2.0 or .NET 2.0 subset).

    It is fixed in 2018.3.

    Not in the same context but I had the same error "Unable to find kernel32.dll" using Unity 2017, .NET 4.X and Mono.

    Switch to Unity 2018.3 fixed it so anyways it worth the try.

    I got the same run-time error as in first post.

    Unity 2017.4.30f1, ILL2CPP, API compatibility level: .NET 4.6

    How to fix it using Unity 2017.4 LTS?
    As I understand I can not use .NET Standard 2.0 in 2017 LTS
    Can anyone help? Solution to use Unity 2018 require some work...

    If I switch to API compatibility level: .NET 2.0 or .NET 2.0 subset the project failed to build.

    As I see most easy way - get rid of XML serialization)
