http://blogs.msdn.com/b/jmstall/archive/2006/08/09/ndepend.aspxI just saw a free cool tool, NDepend , which analyzes .NET assemblies and lets you get neet metrics. It also lets you run queries like: WARN IF Count &gt; 0 IN SELECT TYPES OUT OF NAMESPACES "System.Xml" WHERE DepthOfIsUsing "System.Xml.XmlChildNodesen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/jmstall/archive/2006/08/09/ndepend.aspx#695616Fri, 11 Aug 2006 18:47:16 GMT91d46819-8472-40ad-a661-2c78acb4018c:695616MikeJConwell - It would definitely be cool if VS had this sort of search. I'd love to see this sort of seach possible on the managed heap as well (&quot;find me all objects whose total size &gt; 100k&quot;). <br> <br><div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=695616" width="1" height="1">http://blogs.msdn.com/b/jmstall/archive/2006/08/09/ndepend.aspx#695593Fri, 11 Aug 2006 18:17:58 GMT91d46819-8472-40ad-a661-2c78acb4018c:695593JConwellCan you immagine an VS addin that uses this type of syntax for its Search functionality?<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=695593" width="1" height="1">http://blogs.msdn.com/b/jmstall/archive/2006/08/09/ndepend.aspx#693429Wed, 09 Aug 2006 19:34:28 GMT91d46819-8472-40ad-a661-2c78acb4018c:693429Dan McKinleyYou forgot to mention that it can also emit .xml files that describe the dependencies. I use this (well, a stripped down version of NDepend that runs faster, actually) to support other custom build/project tools that I have written at my company.<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=693429" width="1" height="1">
