-Using the notation @(\<myType>) enables a collection of items of type \<myType> to be expanded into a semicolon-delimited list of strings, and passed to a parameter. If the parameter is of type `string`, then the value of the parameter is the list of elements, separated by semicolons. If the parameter is an array of strings (`string[]`), then each element is inserted into the array based on the location of the semicolons. If the task parameter is of type <xref:Microsoft.Build.Framework.ITaskItem>`[]`, then the value is the contents of the item collection together with any metadata attached. To delimit each item by using a character other than a semicolon, use the syntax @(<\myType>, '<\separator>').
