问题
Further to this question, I have lots of projects inside a solution and I dont want to create a dotsettings file for each project. Can anyone help me set the C# Language Level on a solution level.
This is relevant for me as I downloaded VS2015 today and ReSharper is offering me useful refactor suggestions based on targeting C# 6 and my projects are using C#5.
回答1:
I added below settings in .sln.DotSettings
<s:String x:Key="/Default/CodeInspection/CSharpLanguageProject/LanguageLevel/@EntryValue">CSharp50</s:String>
This line was added to .csproj.DotSettings when I tried to disable c#6 for a particular project. After adding this line in .sln.DotSettings resharper is reporting an error whenever I am trying to use c# 6.0 feature.

According to Jetbrains documentation about C# default version, you can specify the target C# version explicitly by selecting the project in the Solution Explorer and using the C# Language Level property in the Visual Studio's Properties window.
