The examples that are shipped as part of the ObjectDump repository requires LINQPad to run, a free tool made by the author of C# 40 in a Nutshell, a O'Reilly book about C# 4.0, LINQ and various other topics.
Ensure that you load up the solution file in Visual Studio 2015, and do a full rebuild for the Debug target before testing any of the examples. They rely on the binary produced as part of the build output.
