'type': you cannot cast to a type that contains 'auto'
You cannot cast a variable to the indicated type because the type contains the auto keyword and the default /Zc:auto compiler option is in effect.
The following code yields C3537 because the variables are cast to a type that contains the auto keyword.
// C3537.cpp
// Compile with /Zc:auto
int main()
{
int value = 123;
auto(value); // C3537
(auto)value; // C3537
auto x1 = auto(value); // C3537
auto x2 = (auto)value; // C3537
auto x3 = static_cast<auto>(value); // C3537
return 0;
}
