Don't forget add EntitySpaces operands to Where method.
In EntitySpaces you can specify filter to load data. I've wrote the following code EmployeesCollection collection = new EmployeesCollection(); Collection.Query.LastName.L... collection.Query.Load(); and couldn't understand why the filter doesn't work.

DotNetnuke 4.4 RewriterUtils.RewriteUrl breaking change in adding QueryString.
I am using modified version of DNN HttpModules\UrlRewrite\UrlR... in particular I am calling their Friend RewriterUtils.RewriteUrl function. In 4.0.3 version it expected URL parameter without QueryString and added queryString from context.Request.QueryString inside the function.But in 4.4. my code stopped working.The reason was that they removed the code to add querystring information from the function and made it responsibility of a caller.It certainly makes sense, but it will be easier ......
