Are you aware of any information about the more subtle changes between beta1 and beta2

<br>

<br>I just noticed that  Items, of now ObjectModel.Collection&lt;T&gt; is a List but it no longer supports Sort using the default comparer.

<br>

<br>MyCollection : Collection&lt;ComparableObject&gt;

<br>{

<br>     public void Sort()

<br>     {

<br>            base.Items.Sort();

<br>      }

<br>}

<br>

<br>what do you think the best technique to replace this with would be in this scenario ?

<br>

<br>

<br>

Using Power Collections, you could just write:

<br>

<br>   Algorithms.SortInPlace(base.Items);

<br>

<br>With just the .NET Framework, you'd have to copy the list to an array, sort the array, and copy back. Something like (untested code ahead):

<br>

<br>  T[] temp = new T[base.Items.Count];

<br>  base.Items.CopyTo(temp, 0);

<br>  temp.Sort();

<br>  for (int i = 0; i &lt; temp.Length; ++i)

<br>     base.Items[i] = temp[i];

<br>

It turns out that even though items object of Collection&lt;T&gt; is now an exposed as an IList it still does infact use the List&lt;T&gt; object (makes sence) to back up the collection,

<br>

<br>in short you can still do sorting in place with just the frame work alone.

<br>

<br>

<br>((List&lt;[MYTYPE]&gt;)base.Items).Sort()

<br>

<br>

<br>I just took a stab in the dark prayed and it worked, who knows for how long. :)  The joys of beta programing.

<br>

<br>Thanks for taking the time to write back.

When will a new version of the Power Collections be released for beta 2? :)
