I have finally updated the Linq Expressions DebuggerVisualizer to work in VS 2010.

There were a lot of new kind of Expressions introduced so I added support for them too.

You can see it in action with data from the MSDN samples for the SwitchExpression class and the TryExpression class.



You can download the Visualizer here

Some time ago I created a DebuggerVisualizer for LINQ expressions. I have finally updated the DebuggerVisualizer for Visual Studio 2008 RTM version. You can download it here.

The main changes are that Funclets and LiftExpressions were removed after Beta 1. For more information check this post.

I have tested it only in a couple of expressions so let me know if you find any problem.

In a couple of hours I got this DebuggerVisualizer working. </p> <p> For the following expressions: </p> <p style="FONT-SIZE: 10pt; BACKGROUND: white; MARGIN: 0px; COLOR: black; FONT-FAMILY: Courier New"> <span style="COLOR: #2b91af">Expression</span><<SPAN style="COLOR: #2b91af">Func><<SPAN style="COLOR: #2b91af">Person>, <span style="COLOR: blue">bool</span>>> expr1; </p> <p dir=ltr style="FONT-SIZE: 10pt; BACKGROUND: white; MARGIN: 0px; COLOR: black; FONT-FAMILY: Courier New"> <span style="COLOR: #2b91af">Expression</span><<SPAN style="COLOR: #2b91af">Func><<SPAN style="COLOR: blue">int>, <span style="COLOR: blue">string</span>, <span style="COLOR: blue">bool</span>>> expr2; </p> <p dir=ltr style="FONT-SIZE: 10pt; BACKGROUND: white; MARGIN: 0px; COLOR: black; FONT-FAMILY: Courier New"> </p> <p dir=ltr style="FONT-SIZE: 10pt; BACKGROUND: white; MARGIN: 0px; COLOR: black; FONT-FAMILY: Courier New"> expr1 = p => p.Name == <span style="COLOR: #a31515">"Manu"</span>; </p> <p dir=ltr style="FONT-SIZE: 10pt; BACKGROUND: white; MARGIN: 0px; COLOR: black; FONT-FAMILY: Courier New"><= 0) || (str.Length > expr2 = (idx, str) => !((idx 2)); </p> <!--EndFragment--> <p> </p> <p> The visualizer renders the following: </p> <p> <img src="http://www.manuelabadia.com/blog/content/binary/expr1.PNG" border=0> </p> <p> <img src="http://www.manuelabadia.com/blog/content/binary/expr2.PNG" border=0> </p> <p> The nodes in red are terminal expressions (constants or parameters), the nodes in green are objects used by the expression subtree, and the other expression nodes are blue. The properties and fields for each node are loaded on demand and can be inspected when the node is expanded. </p> <p> As expression trees are used to do really cool things I have made a free special version of StructsViz with only the functionaly needed to display expression trees. Due to the crappy NVidia drivers for Vista I haven't been able to test it extensively (as my hard disk stops from time to time, specially with Virtual PC) so let me know if there is any problem. As always, feedback is welcome. </p> <p> To read more about Linq take a look at <a href="http://msdn2.microsoft.com/en-us/library/aa479865.aspx">this article</a> or at <a href="http://weblogs.asp.net/scottgu">ScottGu's excellent posts about Linq</a>. </p> <p> To use the DebuggerVisualizer, create a Visualizers folder inside C:\Documents and Settings\Administrator\My Documents\Visual Studio 2008, and copy the LinqExpressionVisualizer.dll there. </p> <p> Another option is to copy the visualizer to C:\Program FIles\Microsoft Visual Studio 9.0\Common7\Packages\Debugger\Visualizers </p> <p> Please do not distribute the visualizer from your web page.
