I have a problem with link.xml

It's my link.xml info:

Code (csharp):

1. <linker>
2.   <assembly fullname="System">
3.     <type fullname="System.Net" preserve="all"/>
4.     <type fullname="System.Threading" preserve="all"/>
5.     <type fullname="System.Net.Sockets" preserve="all"/>
6.     <type fullname="System.IO" preserve="all"/>
7.     <type fullname="System.Text" preserve="all"/>
8.     <type fullname="System.Collections" preserve="all"/>
9.     <type fullname="System.Collections.Generic" preserve="all"/>
10.     <type fullname="System.Net.WebRequest" preserve="all"/>
11.     <type fullname="System.Configuration.ExeConfigurationHost" preserve="all"/>
12.     <type fullname="System.Configuration" preserve="all"/>
13.   </assembly>
14. </linker>

It's the problem(for xcode throw):

The game I'm working on using several classes from the System.Net.Sockets package. If I run it on a normal build it works perfectly, but if I try to strip it using either StrippingLevel.StripAssemblies or StrippingLevel.StripByteCode stripping levels, it crashes with a*exception (above...).

But, why?

Additional Information:
1, I have implemented Http using System.Net.Sockets.
2, When I use my link.xml, the size of System.dll is increased (259kb).
3, When I only use [StrippingLevel.StripByteCode], the size of System.dll is small (252kb).
4, When I disable the [strip function], the size of System.dll is biggest (1.7m).

 

If I want to ignore all classes of System.dll , How can I do?
Because, I only need to strip my Assembly-CSharp.dll

en... Is this right?

Code (csharp):

1.  
2. <linker>
3.     <assembly fullname="System">
4.         <type fullname="System.*" preserve="all"/>
5.     </assembly>
6.     <assembly fullname="mscorlib">
7.         <namespace fullname="System.*" preserve="all"/>
8.     </assembly>
9. </linker>
10.  

 

Exactly the same issue, someone please help!

 

1. Discover the name of the assembly for excluding

• Build project for windows (or just looking for any dlls in project)
• Got .NET SomeAssemblyBrowser (ILspy or something like this)
• Open in SomeAssemblyBrowser suspected dll libraries (BuildFolder\Managed, BuildFolder\Plugins etc)
• Figure out assembly name by searching for desired namespace

For example you found SomeAssemblyName and SomeNamespaceName within it.
2. Make the file Assets\link.xml:

Code (csharp):

1. <linker>
2.        <assembly fullname="SomeAssemblyName">
3.                <namespace fullname="SomeNamespaceName" preserve="all"/>
4.        </assembly>
5. </linker>
6.  

3. Build project for iOS with this file, set strip level different values and verify that the corresponding BuildFolder/Libraries/SomeLibraryName.dll.s size is changing (also "Other/SystemExecutableAndDll" size in Profiler.Memory.Detailed Take Sample)

 

I encountered the same problem when used HttpWebRequest.
Following link.xml helps:
<linker>
<assembly fullname="System">
<type fullname="System.Net.HttpWebRequest" preserve="all"/>
<type fullname="System.Net.WebResponse" preserve="all"/>
<type fullname="System.Net.HttpRequestCreator" preserve="all"/>
</assembly>
</linker>
But I don't know what's the reason and how to find the corrected type name, anybody can help?

 

Okay, a little help for those searching for some instructions on how this works. This is based on trial and error.

"type" can be either a class name (with full namespace) or just a namespace and every class within that namespace will be excluded.
Child namespaces will not be excluded just by adding the parent namespace. In order to exclude namespaces recursively, use *

Code (csharp):

1. <linker>
2.    <assembly fullname="MyAssemblyName"> // the name of the assembly
3.        <type fullname="MyNamespace" preserve="all"/> // excludes all classes that are direct children of MyNamespace
4.        <type fullname="MyNamespace.*" preserve="all"/> // excludes all namespaces and classes recursively under MyNamespace
5.        <type fullname="MyNamespace*" preserve="all"/> // excludes all namespaces and classes recursively under MyNamespace. Would also exclude the namespace MyNamespaceABC
6.        <type fullname="My*" preserve="all"/> // excludes all namespaces and classes that start with My and all children of those namespaces
7.        <type fullname="*" preserve="all"/> // excludes all namespaces and classes in the assembly
8.    </assembly>
9. </linker>

Essentially, it seems to be just a simple string comparison.

Also, using the namespace element also works. I haven't tested this but I assume it excludes everything within that namespace. Not sure about child namespaces within the parent.

Code (csharp):

1. <linker>
2.    <assembly fullname="MyAssemblyName">
3.        <namespace fullname="MyNamespace" preserve="all"/>
4.    </assembly>
5. </linker>
