Compiler Error C3507

a ProgID can have no more than 39 characters 'id'; nor contain any punctuation apart from '.'; nor start with a digit

The progid attribute has restrictions on the values that it can take.

The following sample generates C3507:

// C3507.cpp
[module(name="x")];
[
coclass,
progid("0123456789012345678901234567890123456789"),
uuid("00000000-0000-0000-0000-000000000001") // C3507 expected
]
struct CMyStruct {
};
int main() {
}
