Could not load file or assembly 'file:///C:\Program Files (x86)\MS Build\ExtensionPack\4.0\MSBuild.ExtensionPack.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the declara tion is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework .ITask.     0 Warning(s)     1 Error(s)   Couple of questions. Is there a "hello world" for MSBuild extension pack? Something that would show that all the paths are correct and the software libraries are installed? I have noticed that directory C:\Program Files (x86)\MSBuild\ExtensionPack\4.0\MSBuild.Extens ionPack.dll does not exist but the installed directory is C:\Program Files\MSBuild\ExtensionPack\4.0\MSBuild.ExtensionPack.dll.   black_13
