    We use the AxSeriel COM Driver from https://www.activexperts.com/serial-port-component/ . It's a DLL that is placed in the Scripts folder and then used in c#.

    In the Editor everything works fine but when we create a build we get the NotSupportedException error thrown.
    The Whole construct worked with the 2018 Version of Unity, after the Update this problem appeared.

    Code (csharp):
    1. System.NotSupportedException: Specified method is not supported.
    2.   at (wrapper cominterop) AxSerial.ComPortClass..ctor()
    3.   at MyNamespace.Serial.SerialManager.initComponents () [0x0005d] in C:\Users\MYUSER\Documents\Unity\MYPROJECT\Assets\Scripts\Serial\SerialManager.cs:86
    4.  
    We've tried verious solutions that we found all over the internet loke creating a DLL folder in the Assets root and palce the dll there and alos copy itin the Unity/Editor folder etc. Nothing worked :/

    Maybe someone have a Hint/Solution for this problem.

    Thanks.

    Which platform are you building to? Did you try using IL2CPP scripting backend?

    What API Compatibility level are you using? Could you try using .NET 4.x?

    Ok it works with .NET 4.x. Didn't thought of that.
    Thank you.

    The reason this worked in the editor is because the editor always runs in .NET 4.x mode, regardless of the player setting.

    I can't but i can explain more now. After hundred tries i found source of this issue. "Managed Stripping Level". When it's enables Low, MEdium or High doesn't matter Issue comes out. Mono or IL2CPP doesn't matter both mode gives this error when managed stripping level enables. I don't took any error in mono because i can disable it. But IL2CPP can't. How can bypass this mode. I read documentation of Managed Stripping Level it says removing unreachable codes. I don't want it. It's killing my game. I can't publish my game with this issue. My game is like a trash and totally waste of time if this issue can't be resolved. Also my other online games because i use them too this plugins. By the way is there any way to bypass to deleting unreachable codes or totally disabling the stripping method in IL2CPP .?

    As mentioned in the "Link XML" section of the documentation here: https://docs.unity3d.com/Manual/ManagedCodeStripping.html, you can add a link.xml file to your project to indicate which assemblies, namespaces, or types should always be preserved.

    Code (CSharp):
    1. <linker>
    2.     <assembly fullname="MySql.Data" preserve="all">
    3.         <type fullname="*" preserve="all"/>
    4.     </assembly>
    5.     <assembly fullname="Newtonsoft.Json" preserve="all">

    12.     <assembly fullname="UnityEngine" preserve="all"/>
    13.     <assembly fullname="mscorlib" preserve="all"/>
    14. </linker>

    I allready made this yesterday and also i tried 45 times over with changing something but no it doesn't changed anything. Package size chganged so seems linker doing something but my plugins or my code still doesn't work. What i must do ?, i'm really confused.

    I think the best option now if to try to get a full stack trace when the error occurs. Maybe this is unrelated to managed cod stripping entirely.

    Can you try to add this line to the link.xml file?

    <assembly fullname="System.Data" preserve="all"/>

    It looks like the code here is in System.Data.dll. I don't think the the linker should be removing this code though, so I'm still unclear why this is happening. But lets start here to see if you can work around the issue.

    Hi again i added line but still not working. Also i guess nothing doesn't changed yet. But package size increased. So i think we are going to solve this issue.
    here is new link.xml:
    Code (CSharp):
    1.  
    2. <linker>
    3.     <assembly fullname="MySql.Data" preserve="all">
    4.         <type fullname="*" preserve="all"/>
    5.     </assembly>
    6.     <assembly fullname="Newtonsoft.Json" preserve="all">
    7.         <type fullname="*" preserve="all"/>
    8.     </assembly>
    9.     <assembly fullname="Assembly-CSharp" preserve="all">
    10.         <type fullname="*" preserve="all"/>
    11.     </assembly>
    12.     <assembly fullname="System" preserve="all"/>
    13.     <assembly fullname="System.Data" preserve="all"/>
    14.     <assembly fullname="UnityEngine.CoreModule" preserve="all"/>
    15.     <assembly fullname="mscorlib" preserve="all"/>
    16. </linker>
    17.  
    here is new stack trace:

    Huh, it looks like nothing changed there. That is very odd. As a sanity check, how is the MySql.Data.dll compiled? Is it compiled against .NET Standard 2.0? Or is is compiled against .NET Framework?

    Ok, the .NET 4.5 version should work. Can you submit a bug report with this project? Something is wrong here that I do not understand.

    Hı Josh;

    I came back with detailed issue. After deep searching of all stack trace by one by i found the complete source of issue.

    MySQLConnection is uses MySqlConnectionStringBuilder when connection is building, after building connection is calling MySqlConnectionStringBuilder.Clear(). The issue comes here. This is Also called IDictionary.Clear() from System.Collections.cll and mscorlib.dll.

    IDictionary.Clear() methods throws NotSupportedException when it's readonly. I cannot change MySqlConnectionStringBuilder dictionary to editable. Method has only get; property.
    So this issue always will come up. If an error occurs in the code, the codes below will be not read and execute. So if i can bypass the exception, the codes below from exception are will read and executed .?
    If yes i think i can handle this with try catch am i wrong ?.

    Also what happens during stripping assemblies to this error comes up. With stripping assemblies disabled MySqlConnection clearly call MySqlConnectionStringBuilder.Clear() with no error. I don't understand what stripping assemblies exactly doing.

    This is MySqlConnectionStringBuilder class's document:
    https://dev.mysql.com/doc/dev/conne..._MySqlClient_MySqlConnectionStringBuilder.htm

    This is MySqlConnectionStringBuilder.Clear method's document:
    https://dev.mysql.com/doc/dev/conne...Client_MySqlConnectionStringBuilder_Clear.htm

    This is IDictionary.Clear method's document !! SOURCE OF ERROR !!:
    https://docs.microsoft.com/en-us/do...=net-5.0#System_Collections_IDictionary_Clear

    Thanks for the additional details. I'm still unsure what is causing this issue. Our QA team is processing the bug report you submitted - once they do that we will investigate it.

    I have this error as well. Any updates?

    I get the stack trace below. The similarity seems to be these are both `EventSource` subclasses, with a method having the `EventAttribute` attribute.
    I get this in Unity 2021.1 and 2021.2 when using IL2CPP, with API Compatibility Level set to .NET Standard 2.1, or .NET Framework

    Code (CSharp):

    It looks like our QA team was unable to reproduce the problem in the initial bug report, so we've not investigated this issue.

    Did this code work in versions of Unity prior to 2021.1?
