Compiled code on Windows with Visual Studio 2012

Compile this program on Windows with Visual Studio 2012:

class Program
    static void Main(string[] args)
        var identity = System.Security.Principal.WindowsIdentity.GetCurrent();

        if (System.Type.GetType("Mono.Runtime") == null)
            // shouldn't be run on mono
            // shouldn't crash either

Run it on mono:

$ mono ConsoleApplication1.exe
Missing method get_Name in assembly /home/ubuntu/ConsoleApplication1.exe, type System.Security.Claims.ClaimsIdentity

Unhandled Exception:
System.TypeLoadException: Could not load type 'System.Security.Claims.ClaimsIdentity' from assembly 'ConsoleApplication1'.
[ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: Could not load type 'System.Security.Claims.ClaimsIdentity' from assembly 'ConsoleApplication1'.

$ mono --version

Comment 1 Rodrigo Kumpera 2013-05-17 13:18:51 UTC
You cannot use unavailable types and methods in the same method you check for mono presence.

Move usage to System.Security.Claims.ClaimsIdentity in a separate method and use the type test guard to call it or not.
Comment 2 catgotyrtongue 2013-05-17 14:16:46 UTC
This type and methods are available, it works perfectly if it's compiled with mono.
Comment 3 Rodrigo Kumpera 2013-05-17 14:20:59 UTC
Then I fail to see what's the problem you're suggesting that exists.
Comment 4 catgotyrtongue 2013-05-17 14:22:35 UTC
If I compile my library (e.g. Npgsql) on Windows and then want to distribute it with my application, it will not run on mono.
Comment 5 Rodrigo Kumpera 2013-05-17 15:12:01 UTC
Because it will throw the above exception, right? I explained why it will and how to avoid it. It's not a bug but just how things work.

You cannot have missing types/methods on methods that are executed, even if you don't call them.
Comment 6 Timothy 2013-10-15 07:03:03 UTC
I don't think this is resolved.
Sure your first reply pointed out why he gets the TypeLoad exception
but it does not solve/explain why the following code works fine if you compile with mono and doesn't work when you compile with .NET (visual studio)

var identity = System.Security.Principal.WindowsIdentity.GetCurrent();

The proper execution of the code above should not depend on 
the compiler that has been used.

If you still refuse to see the issue,
consider the following example:


compile it with gmcs (mono) and with csc (.net) and try to run
both versions with mono.
