Unity Project doesn't have solution file

问题

I just started learning unity and I created a project. But my project doesn't have a sln file included in. Every time I create a C# script and open it in Xamarin Studio I can't have any intellisense.

1. Is it normal not to have sln file in unity project?
2. If not, how can I add solution file to project?
3. Why that happened?

回答1:

I finally found the answer.

I closed Xamarin and inside Unity went Assets > Sync MonoDevelop Project Doing this created the two .sln projects: -csharp.sln and .sln
