Now I have lot of work, when I looking for solution how my old projects working with new Unity version.
I used older Unity 5 version and Monodevelop. I updated it and now I can not compile, because there is Visual Studio.
If needs add Visual Studio to Unity please ensure that it also works with monodevelop. This is for developteam, please do testings first that it workin fine. I know Visual Studio quite well, but I am not sure that it is good “integrate” it to Unity if making breaking changes same time. Because also Monodevelop is quite good tool for c# coding.
When making software needs really ensure is it really important to make some new feature if it will break some old feature, because lot of projects is made by using old features.
Also yesterday I tested, I made new project and make one c# script by using Visual Studio, and it worked fine in the new Unity version. Today I installed it again and anytihing not work. I needs test again by reinstall all. But also needs looking for where is some wrong path (monodevelop).
It looks like you have some pathing issues or something wrong with the car it is referencing there. Did you install to default directory? Did you have a beta version installed before this version?
I took back version 5.0.0 now c# compiler works fine and c# editor is Monodevelop. But projects UI layout not work. He he. So Unity minor versions they are so sensitive. Needs to be carefull.
