Static function does not see members of enclosing type

[OndrejPetrzilka]

struct PassInterface
{
    float3 BaseColor;
    float Metalness;
    float3 Normal;
    float Roughness;

    static PassInterface Create(float3 color = 0, float3 norm = 0, float rough = 1, float metal = 0)
    {
        PassInterface result;
        result.BaseColor = color; // 'PassInterface' does not have a field 'BaseColor'
        result.Normal = norm; //'PassInterface' does not have a field 'Normal'
        result.Roughness = rough; // here too
        result.Metalness = metal; // here too
        return result;
    }
};

When I only declare function within struct and it's implementation is below, it works fine
