Question

操作系统：Windows 7专业版。

我们正在使用Roslyn打开.csproj文件，以使用以下代码获取其编译详细信息：

using (var workspace = MSBuildWorkspace.Create())
{               

   Project currentProject = workspace.OpenProjectAsync(projectPath).Result; 
   Compilation compilation = currentProject.GetCompilationAsync().Result;
}

该代码适用于文件路径少于260个字符的.csproj文件。但是，在打开文件路径大于260个字符的.csproj文件时，代码会抛出异常。

    System.AggregateException: One or more errors occurred. ---> 
    System.IO.PathTooLongException: The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

但是这个限制必须有一些解决方法。我们正在寻找解决此问题的某些选择。

注意：

我们无法将文件路径更改为较短的文件路径。
我们已经尝试了 subst 选项，但它仍然不是完整的证明选项。

调用MSBuildWorkspace.OpenProjectAsync时出现System.IO.PathTooLongException
