+Summary: Type arguments of custom attributes in System assembly have wrong type names in IL
+
+Apparently, some Type arguments of custom attributes in, for example, the 
+System assembly have a bad type name.
+
+For example, look at the IL that's emitted for the 
+System.ComponentModel.TypeConverterAttribute of the 
+System.ComponentModel.IComponent interface in the System assembly.
+
+The ctor of the TypeConverterAttribute takes a Type, and in the source 
+its defined like this :
+
+[TypeConverter (typeof (System.ComponentModel.ComponentConverter))]
+
+However, in the emitted assembly the type name looks like this :
+
+System.ComponentModel.ComponentConverter, System, Version=0.0.0.0, 
+Culture=neutral, PublicKeyToken=null
+
+Ofcourse both the version number and the publickeytoken are not correct.
+
+Also MS does not emit an AssemblyQualifiedName if the type is in the same 
+assembly.
+
+Note: On Windows I can no longer build Mono, and I think it might be 
+because of this issue. 
+
+If I'm not mistaken, the 1.0 profile assemblies are built using csc on 
+Windows. This means that the Type argument is emitted with its full name 
+and not its assembly qualified name. 
+
+Then when the 2.0 profile is bootstrapped its first uses the System 
+assembly built using csc and fails when verifying CLS compliance as csc 
+did not emit assembly qualified type names (for Type arguments of custom 
+attributes) and apparently mcs relies on these being fully qualified.
