当运行以下命令时dnu publish，我抛出一个 ArgumentNullException 异常。
dnu publish "C:\Project\MyProject" --out "C:\a" --configuration Debug --runtime dnx-clr-win-x86.1.0.0-beta6
抛出异常：
Restoring packages for C:\a\approot\src\RelatedProject\project.json

The project.json相关项目如下：
{
"version": "1.0.0-*",
"description": "MyProject.Domain.Model Class Library",
"dependencies": {
"System.Collections": "4.0.10-beta-23019",
"System.Linq": "4.0.0-beta-23019",
"System.Threading": "4.0.10-beta-23019",
"System.Runtime": "4.0.10-beta-23019",
"Microsoft.CSharp": "4.0.0-beta-23019"
},
"frameworks": {
"net451": { }
}
}
问题归结为 MyProject 的目标是dnx451和相关项目（由 MyProject 引用）的目标是net451。将相关项目更改为目标dnx451解决了问题dnu publish.
