My code:

        ws.CategoryConfiguration cc = new ws.CategoryConfiguration();
        cc.LoadChildProducts = true;
        cc.ChildProducts.SearchOptions.PropertiesToReturn = new string[] { "BasePrice" };

when I run this, I get a NullReferenceException on the ChildProducts line. I know that string[] is an object because it's right there, so it must be PropertiesToReturn. Anyone know what the issue is? LoadChildProducts works without any issue.

You need to new up the SearchOptions object, like this:

CatalogSearchOptions searchOptions = new CatalogSearchOptions();

Then you can add the PropertiesToReturn, like this: 

searchOptions.PropertiesToReturn = "BasePrice";

Finally, you can assign the searchOptions to the CategoryConfiguration.ChildProducts.SearchOptions property, like this:

cc.ChildProducts.SearchOptions = searchOptions;

It is either the ChildProducts or the SearchOptions inside the ChildProducts.
Make sure that they get initialized in the constructor of a CategoryConfiguration
