Question

I’ve recently upgraded my project from Visual Studio 2008 to Visual Studio 2010.

By enabling Code Analysis and building on Release, I’m getting warning CA1811: Avoid uncalled private code.

I’ve managed to reduce the code to this:

.h file:

public ref class Foo
{
public:
    virtual System::String^ ToString() override;

private:
    static System::String^ Bar();
};

.cpp file:

String^ Foo::ToString()
{
    return Bar();
}

String^ Foo::Bar()
{
    return "abc";
}

The warning I get:

CA1811 :
Microsoft.Performance :
‘Foo::Bar(void)’ appears to have no
upstream public or protected
callers.

It doesn’t matter if Bar() is static or not.

I’ve tried to reproduce it in C# but I can’t. I can only reproduce it in C++/CLI.

Why do I get this warning?

Is this a Visual Studio 2010 bug?

UPDATE

I’ve decided to open a bug report on Microsoft Connect.

Answer 1

Microsoft guys have reproduced this bug and decided not to fix it.

Suppressing the warning is the workaround.
