this->ProgressBar1->Value += 1;
//This is the target value
if (this->ProgressBar1->Value == 10)
{
    //this line of code just doesnt work... icannot compile Please help.
    this->ProgressBar1->Visibility = Visibility->Collapsed;

需要使用命名空间

this->ProgressBar1->Visibility = Windows::UI::Xaml::Visibility::Collapsed;
