Linq: Order by date and Find the first element

Linq: Order by date and Find the first element

I want to query a datatable where i select list of rows based on some data
and order the rows by date and get the row with latest date. This is what
I did
var propertyValueId = _dbSis.Set<PropertyValue>()
.Where(m => m.PropertyInstanceId == id)
.OrderBy(z => z.TimeStamp);
var pvalueId = propertyValueId.ElementAtOrDefault(0);
but I get error on propertyValueId.ElementAtOrDetault(0);
LINQ to Entities does not recognize the method
'Sorama.DataModel.SIS.Configuration.PropertyValue
ElementAtOrDefault[PropertyValue](System.Linq.IQueryable`1[Sorama.DataModel.SIS.Configuration.PropertyValue],
Int32)' method, and this method cannot be translated into a store
expression.
How can I achieve what I just expected, and how can i solve the error?
