Compiler Error C3539

'type': a template-argument cannot be a type that contains 'auto'

The indicated template argument type cannot contain a usage of the auto keyword.

To correct this error

  •  Do not specify the template argument with the auto keyword.

The following example yields C3539.

// C3539.cpp
// Compile with /Zc:auto
template<class T> class C{};
int main()
   C<auto> c;   // C3539
   return 0;
