Visual Studio 2017: How to show "System" and c# related documents other than "UnityEngine"?

Example:

In Visual Studio 2017, Unity Project, when I move my mouse hover on the class name "MonoBehaviour", it will show the documentation "Monobehaviour is the base class from..."

But in Unity Project, I don't have those documentation for c# standard classes. for example, when I hover my mouse on "string", it shows no document.

But in non-Unity Project, in WPF project for example, there will be documentation like "Represents text as a sequence of..."

How to solve that? How to enable c# standard class documentation in Unity?

 

Provided you have

Code (csharp):

1.  
2. using system;
3.  

You should be fine. If I understand rightly, you are referring to the summary of Unity members.

 

I don't mean that I have compiler error, I mean I don't have C# document that I should have.

Here are the screenshots.

This is non-Unity project documentation for File class (documentation language is chinese.)


This is Unity project "documentation" for File class, there are no documentation at all.

I believe that information is embedded in the xml files of the same name next to the dll.

So if you right click UntiyEngine in your solution explorer's References, and check the path, you'll find that it's placed in:
Path_to_game\Library\UnityAssemblies\UnityEngine.dll

Next to UnityEngine.dll, there will be a UnityEngine.xml file with all of the docs.

For the System.dll, there's no such xml file. For me, it's placed in:
C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v3.5\Profile\Unity Subset v3.5

I'm not sure where you'd get access to the doc files.

 

Thank you, after copy those related xmls from 3.5 Profile Client to Unity Subset v3.5, they showed up!

Problem solved. But if there are better solution, please post it.
