Question

I have VS community 2019 version is 16.11.17. In my C# unity project i need language version 9.0 but when i try to open project properties window it does nothing. How can i fix it???

Answer 1

Double click the project name in Solution Explorer to open the project file. Alter LangVersion as shown below and save. The only reason this will not work is if the .NET Core framework is not installed.

<Project Sdk="Microsoft.NET.Sdk">  
 <PropertyGroup>  
 <OutputType>Exe</OutputType>  
 <TargetFramework>net5.0</TargetFramework>  
 <LangVersion>9.0</LangVersion>  
 </PropertyGroup>  
</Project>
