Doesn't compile in .NET Core 3.1

Thx for posting this utility/tool! Just had one issue when trying to use it...getting compile error with this source code.
It looks like you may be missing the code for the extension method GetElementsResult()?

[hexpl0it]

you can replace this line
KeyValuePair<PropertyInfo, DataMemberAttribute>[] pairs = typeof(TEntity).GetElementsResult().ToArray();
with this
KeyValuePair<PropertyInfo, DataMemberAttribute>[] pairs = typeof(TEntity).GetProperties().Select(x => new KeyValuePair<PropertyInfo, DataMemberAttribute>(x, (DataMemberAttribute)x.GetCustomAttribute(typeof(DataMemberAttribute)))).ToArray();
