XmlSerializers with addin outlook

I’m trying to create add-in for outlook and have issue with deserialization and antivirus program.

I’ve noticed that when my add-in tried to deserialize any data, .NET framework created temporary dll in “C:\Users\{UserName}\AppData\Local\Temp\" folder.
This dll existed very short time, but from time to time antivirus locked it and add-in thrown error message that file is used by another process.

I’m tried to get rid of temporary dll and found recommendations to use sgen tool for creation of XmlSerializers.dll.

I generated MyAssembly. XmlSerializers.dll with strong name and placed it to the folder with add-in (C:\Program Files (x86)\MyAddin). But it doesn’t help.

Then I tried to place MyAssembly. XmlSerializers.dll to GAC and then to outlook folder, but had no success. When dll was called from GAC I got following error message, but dll has no any reference.

"System.IO.FileNotFoundException: Could not load file or assembly or one of its dependencies. The system cannot find the file specified."

Please add any thoughts how can I to get rid of temporary dll
