I don’t know how this happened but for the last couple years (at least), whenever I read an author who writes about ORMs, I often see a sentiment like this: “ORMs are fine, just make sure you disable this pesky feature called Lazy Loading”.
It’s like this feature is not even needed and only brings confusion and performance issues to everyone who chooses to use it. Well, as you may guess from the title of this article, I disagree with this point of view completely.
.NET 6 Preview 1 is now available and ready for evaluation. This is the first preview of .NET 6, the next major update to the .NET platform. .NET 6 is expected to ship in November of this year, and will be a Long Term Support (LTS) release.
In any real world enterprise application, you end up writing a lot of similar, tedious boilerplate code for bookkeeping . This logic results in a data model where each table is adorned with a lot of non-domain specific columns – does this look familiar?
Compiler – Support for ReadOnlyReferences
class Type1
{
// This parameter will have an attribute (in IL) of type `IsReadOnly`
public void Method1(ref readonly int param1) { throw null; }
// This method return type will have an attribute (in IL) of type `IsReadOnly`
public ref readonly int Method2() { throw null; }
}
HTML5 added a whole bunch of useful new values for the rel attribute, one of which is noreferrer
(yes, spelt correctly this time). When this attribute is added, the
browser is instructed not to set the header if the user follows the
link.

{
var obj = new T();
var properties = typeof(T).GetProperties();
var queries =new NameValueCollection();

queries= HttpContext.Current.Request.QueryString;
else
{
queries = HttpContext.Current.Request.Form;
}
foreach (var property in properties)
{
foreach (Attribute attribute in property.GetCustomAttributes(true))
{
var requestBodyField = attribute as RequestBodyField;
if (requestBodyField == null) continue;
//get value of query string
var valueAsString = queries[requestBodyField.Field];
if (valueAsString == null)
{
var keys = from key in queries.AllKeys where key.StartsWith(requestBodyField.Field) select key;
if(!keys.Any())
continue;
var collection = new NameValueCollection();
foreach (var key in keys)
{
var openBraketIndex = key.IndexOf("[", StringComparison.Ordinal);
var closeBraketIndex = key.IndexOf("]", StringComparison.Ordinal);
if (openBraketIndex < 0 || closeBraketIndex < 0)
throw new Exception("query string is crupted.");
openBraketIndex++;
//get key in [...]
var fieldName = key.Substring(openBraketIndex, closeBraketIndex - openBraketIndex);
collection.Add(fieldName, queries[key]);
}
property.SetValue(obj, collection, null);
continue;
}
var converter = TypeDescriptor.GetConverter(property.PropertyType);
var value = converter.ConvertFrom(valueAsString);
if (value == null)
continue;
property.SetValue(obj, value, null);
}

return obj;
