I think that my previous post could answer the question - so you can consume both methods from a managed C++ client? If the IL is same for both methods, then at least Microsoft should have added a HideFromNonMcppCompilers (or something like this) to the method as well, so non-MC++ clients cannot see the "offending" method.
I have changed the code to :
public __gc class MyClass
{
public: void foo(MyClass* const a)
{
System::Console::WriteLine("void foo(MyClass* const a)");
} void foo(const MyClass* a)
{
System::Console::WriteLine("void foo(const MyClass* a)");
} void boo()
{
const MyClass* myClass;
this->foo(myClass);
} void boo1()
{
MyClass* const myClass = 0;
this->foo(myClass);
}};
Then created C# executable with main:
MyClass a = new MyClass();
a.boo();
a.boo1();The output is:
void foo(const MyClass* a) void foo(MyClass* const a)
The IL code for those methods differ only by method tokens.

Are you new to .NET? AFAIK no .NET-enabled language except C++ supports object const-ness. It is interesting though that you managed to compile the class with the MC++. In .NET (as opposed to C++, where const rules) you'll have to learn to deal with readonly (initonly) fields, get/set properties, read-only collections (or similar patterns) to prevent object clients to modify the instance, etc., etc.
IMHO losing const is a drawback but this has been discussed many times
and I don't want to start any religious wars.
Maybe I wasn't clear enough. Or perhaps I should make the question different. I wonder why the MC++ compiler allows the constructs as below and generates the same IL code for both of the methods.

Hi,
Lets say I have a class:
public __gc class MyClass { public:
void foo(MyClass* const a) { }
void foo(const MyClass* a) { } };
Why is the IL code generated by MVC++ the same for both those methods?
Is there any way to use such method in C# code? Currently I have:
e:\classlibrary1\class1.cs(34,13): error CS0121: The call is ambiguous
between the following methods or properties: 'ManagedClass.MyClass.foo(ManagedClass.MyClass)' and 'ManagedClass.MyClass.foo(ManagedClass.MyClass)'
Thanks,
Regards, Bogdan
