如何将VS2017与Unity 2018一起使用

Question

I'm new with Unity and I have problem with target .Net Framework version in the project. Visual Studio shows me this message …

… but I already have .Net framework 3.5 installed. What can I do?

Message:

The C# Project "Assembly-CSharp" is targetting ".NET Framework, Version=v3.5", which is not installed on this machine. To proceed, select an option below.

• Change the target to .Net Framework 4.6.1
• Download the targeting pack for ".Net Framework, Version=v3.5"
• Do not load the project

Answer 1

I faced this before. You can download targeting pack for developer from microsoft. Done!

Answer 2

Found the fix! go to this directory C:\\Program Files (x86)\\Reference Assemblies\\Microsoft\\Framework.NETFramework

Then create a folder named 4.6.1

Copy all files from 3.5 folder Paste them all in 4.6.1 folder Done!
