Summary: Appdomain.GetAssemblies() returns assemblies loaded
for reflection only, not just for execution. Different
behaviour than .NET
Classification: Mono
Product: Mono: Class Libraries
Version: 2.4.x
Platform: i686
OS/Version: Ubuntu
Status: NEW
Severity: Normal
Priority: P5 - None
Component: CORLIB
AssignedTo: [email protected]
ReportedBy: [email protected]

When calling Appdomain.GetAssemblies() one should get an array with all
assemblies currently loaded in execution context.
See
http://msdn.microsoft.com/en-us/library/system.appdomain.getassemblies.aspx
"Gets the assemblies that have been loaded into the execution context of this
application domain."
Mono 2.4 release tarball does not follow this.
Simple test program to run under .net and mono
-------------
using System;
using System.Reflection;
class GetAssembliesBug
{
static void Main(string[] args)
{
Console.Out.WriteLine("Loaded in execution context: {0}",
AppDomain.CurrentDomain.GetAssemblies().Length);
Console.Out.WriteLine("Loaded in reflection context: {0}",
AppDomain.CurrentDomain.ReflectionOnlyGetAssemblies().Length);
Assembly loaded =
Assembly.ReflectionOnlyLoad(typeof(System.Data.SqlDbType).Assembly.FullName);
Console.Out.WriteLine("Loaded in execution context: {0}",
AppDomain.CurrentDomain.GetAssemblies().Length);
foreach(Assembly a in AppDomain.CurrentDomain.GetAssemblies())
Console.Out.WriteLine("\t{0} in {1} context", a.GetName().Name,
a.ReflectionOnly ? "reflection" : "exec");
Console.Out.WriteLine();
Console.Out.WriteLine("Loaded in reflection context: {0}",
AppDomain.CurrentDomain.ReflectionOnlyGetAssemblies().Length);
foreach(Assembly a in
AppDomain.CurrentDomain.ReflectionOnlyGetAssemblies())
Console.Out.WriteLine("\t{0} in {1} context", a.GetName().Name,
a.ReflectionOnly ? "reflection" : "exec");
Console.In.ReadLine();
}
}
-----
Result in .net:
Loaded in execution context: 4
Loaded in reflection context: 0
Loaded in execution context: 4
mscorlib in exec context
GetAssembliesBug in exec context
System.Data in exec context
System in exec context
Loaded in reflection context: 1
System.Data in reflection context
---------
Result in mono:
Loaded in execution context: 3
Loaded in reflection context: 0
Loaded in execution context: 4
System.Data in reflection context
System.Data in exec context
GetAssembliesBug in exec context
mscorlib in exec context
Loaded in reflection context: 1
System.Data in reflection context

Here is my patch for 2.4 branch in SVN (works for me(tm)):
Index: mono/metadata/appdomain.c
===================================================================
--- mono/metadata/appdomain.c (revision 132563)

+ continue;
if (ass->corlib_internal)

g_ptr_array_add (assemblies, ass);
Reproducible: Always
Steps to Reproduce:
Run supplied test program
Actual Results:
Assemblies loaded in reflection context are returned from both GetAssemblies
and ReflectionOnlyGetAssemblies. This causes portability issues.
Expected Results:
Assemblies should not be returned from GetAssemblies
