Custom Claims Principal

[RafaelMontegordoFelix]

Hi there,
I'm using claims transformation, to inject a CustomClaimsIdentity, that uses other properties than claims.

public CustomPrincipal(ClaimsPrincipal principal, Custom type, long userId) : this (principal)
{
RuleType = type;
UserId = userId;
}

public bool Method(List ids)
{
throw new NotImplementedException();
}

My problem is that when i get the user, i was getting a ClaimsPrincipal, that was not my Custom.
This is because you always create a new ClaimsPrincipal

{
var transformedPrincipal = await _options.ClaimsTransformation(context.Authentication.User);
context.Authentication.User = new ClaimsPrincipal(transformedPrincipal);
}

Is this really necessary? Do you know any problem that can happens if the new was removed and set to the transformedPrincipal?

Thanks
