IL2CPP stripping help.

Question

Hello there,

Relevant Info: iOS, IL2CPP, stripping disabled, works in Mono2x

Situation:

My emailing script doesn't work because some of the types used in it are being stripped out. The problem is that System.Net.Configuration.MailSettingsSectionGroup's constructor keeps getting stripped regardless if it's in the link.xml or not. I've seen on the help forms that Josh Peterson has said to add it to the link.xml file and he provides a link (http://docs.unity3d.com/Manual/iphone-playerSizeOptimization.html) but apparently I can't do anything right because it's still being stripped. my link.xml which is in my assets folder is also provided below.

Question:

Can someone help me figure out how stop System.Net.Configuration.MailSettingsSectionGroup from being stripped. My link.xml has become a large tangled mess because of my lack of understanding.

Thanks in advance for all you help! have a great day.

Xcode Error:

 MissingMethodException: 
 Method not found: 'Default constructor not found...ctor() of 
 System.Net.Configuration.MailSettingsSectionGroup'.

so it turns out that Link.xml != link.xml on a Mac. i simply renamed the file from Link.xml to link.xml and it worked. (note: the link.xml I provided has many problems would not use it)

Thanks in advance for that !!! :)

The problem @ToxicGue is describing is that the "L" in Link was upper case but on a mac there is an expectation that the case is sensitive and needed to be a lower "l" in the word "link", so ins$$anonymous$$d of "Link.xml" it worked fine as "link.xml"

Thanks @Landern but @ToxicGue is saying in is response that the link.xml he provided has many problems and would not use it

That why I want to know what is the problem inside his link.xml :)

@Eonirma the problem with the link.xml file above was that, through my rage I had started to just put namespaces in as assembly names. then, when I got unity to finally find the link.xml file the game would not compile because the linker would look for the namespaces which would not exist in the assembly (or something like that) unity would give me an error saying blank does not exist and could not me preserved (something along that line). To fix this I simply removed the fake assmebly names from the link.xml file. After this everything worked well.

just for completeness, my final link.xml is listed below.

--------------------- NEW link.xml ----------

 <linker>
     <assembly fullname="System">
         <type fullname="System.Net.Configuration.$$anonymous$$ailSettingsSectionGroup" perserve="all"/>
         <type fullname="System.Net.Configuration.WebRequest$$anonymous$$oduleHandler" preserve="all"/>
         <type fullname="System.Net.HttpRequestCreator" preserve="all"/>
         <type fullname="System.Net.FileWebRequestCreator" preserve="all"/>
         <type fullname="System.Net" preserve="all"/>
         <type fullname="System.Net.$$anonymous$$ail" preserve="all"/>
         <type fullname="System.Net.Security" preserve="all"/>
         
         <type fullname="System.Net.Configuration.NetSectionGroup" preserve="all"/>
