I'm interested in enum generic constraints, but when I'm switching language version for project on Build → Advanced I'm still getting error «not available in C#5; please use language version 7.3 or greater» even after reopening the project.
Project type is an ASP.NET MVC application.

I've installed Microsoft.Net.Compilers and Microsoft.CodeDom.Providers.DotNetCompilerPlatform packages from Nuget, then changed in web.config system.codedom → compilers → compiler language="c#;cs;csharp" property langversion to 7.3, reloaded project and all worked.
