Group by case sensitive

[fooo]

Working with RavenDb 6 in c#.
Case sensitive queries are possible e.g using _exact: true in the WHERE.
Now I also want to do a case sensitive GROUP BY.

GroupBy(i => i.Prop, StringComparer.Ordinal)

doesn't seem to work. Any suggestions?

By default, group by is case sensitive.
You don't need to do anything to enable that.
If you need it to be case insensitive, you need to GroupBy(x=>x.Prop.ToLowerInvariant())
