Problem reading .ini file --> "Attempt by security transparent method"

[marco.santilli@2023]

I have problems reading an .ini file in the public folder
everything works locally, both under iss and in visual studio 2019 virtualization
but when i go online i get this text

-------------------------------------------------------------
Attempt by security transparent method 'TradingDomasa.IniFile2.ReadValue(System.String, System.String)' to call native code through method 'TradingDomasa.IniFile2.GetPrivateProfileString(System.String ByRef, System.String ByRef, System.String ByRef, System.Text.StringBuilder, Int32, System.String ByRef)' failed. Methods must be security critical or security safe-critical to call native code.

System.Web.UI.Control.LoadRecursive() +61

instead if I try to read an XML file always present in the public folder, it doesn't give me an error and everything works correctly

Do you have any tips to try?

Hello and thanks
