When using metric source-generator with a strong-typed metric the number of dimensions is limited to 30, i.e. if you try to create a metric with more than 30 dimensions you'll get an error METGEN013 "A metric class contains too many tag names".

[Counter(typeof(SomeType))]
public static partial SomeMetric CreateSomeMetric(Meter meter);
public class SomeType
{
 public string D1 { get; set; } = string.Empty;
 ...
 public string D33 { get; set; } = string.Empty;
}

At the same time, if you specify tag names as a parameter of a metric attribute the issue will not occur and the metric will be successfully created/generated:

[Counter("D1", ..., "D33")]
public static partial SomeMetric CreateSomeMetric(Meter meter);

We should unify the behavior and remove the limitation on the number of tag names in a metric type.
