这是有问题的，因为传入的任何属性都会丢失。

进一步说明：我将一个属性传递给项目文件。此属性是 .props 文件的路径。它包含 detokenise 类的标记和替换值。该任务显然会重新加载项目并且不维护路径。其他任务似乎并非如此，例如 guid 任务。

在示例中，我使用了一个名为 guids.proj 的示例项目

调用使用： 

<MSBuild.ExtensionPack.FileSystem.Detokenise TaskAction="Detokenise" TargetFiles="@(FileCollectionToBeDetokenized )"/>

一些命令行输出如下：

Task "MSBuild.ExtensionPack.FileSystem.Detokenise" (TaskId:11) Detokenise Task Execution Started [13:04:35] (TaskId:11) Loading Project: C:\Users\bstrausser\Desktop\guids.proj (TaskId:11) Detokenising Collection: 1 files (TaskId:11) C:\Users\*****\Desktop\guids.proj(37,9): error : Property not found: Asset Directory
