Oxide core fails to compile

Heyo! Was anything changed? I'm working on my plugins under the oxide project itself(it just easier to look what some functions actually does and how the work). But now I have a problem right now.
For some reason oxide wont compile core and some projects (medival and sapce engineers).
It says something about XML, or so, I don't quite get the error. Never saw anything like that before.
It says that XML default namesspace should be MSBuild XML....
Does the source code path cnahged? I'm using the one from here - GitHub - OxideMod/Oxide: Core mod and extensions for the Oxide mod framework.

 

I can show you what I see, but..... I'm using VS in russian, so there won't be much help. SO the path was not changed and the latest source are still there?
Dang. I have no idea what can be a problem.
Gimmi a moment and I'll change the lang.
[DOUBLEPOST=1507913413][/DOUBLEPOST]Actually what I see is :

Code:

D:\Games\Rust\Oxide\Oxide.Core\Core.csproj : error  : пространством имен XML по умолчанию для этого проекта должно быть пространством имен MSBuild XML. Если проект создан в формате MSBuild 2003, добавьте xmlns="http://schemas.microsoft.com/developer/msbuild/2003" в элемент <Project>. Если проект был создан в старом формате 1.0 или 1.2, преобразуйте его в формат MSBuild 2003.  D:\Games\Rust\Oxide\Oxide.Core\Core.csproj

 

Are you seriouse? 2017? Why so?
Yep. 2015 as it use to be. So this is a problem, right?

 

Code:

D:\Games\Rust\Oxide\Oxide.Core\Core.csproj : error  : The default XML namespace of the project must be the MSBuild XML namespace. If the project is authored in the MSBuild 2003 format, please add xmlns="http://schemas.microsoft.com/developer/msbuild/2003" to the <Project> element. If the project has been authored in the old 1.0 or 1.2 format, please convert it to MSBuild 2003 format.  D:\Games\Rust\Oxide\Oxide.Core\Core.csproj

So the problem is that I'm using VS 2015 insted of 17?

 

Use Rider.
Visual Studio - fucking program with lags.
