Why are .java files generated when .cs should be in c#/Antlr4.Runtime.Standart?

Question

I need to write a translator for the language. I decided to use ANTLR4. The files for the parser are generated for Java, but I need them to be generated for C#. What do I need to add or do to change the language for which files will be created?

According to the documentation, I installed the Nuget package Antlr4.Runtime.Standart, and also installed the extension in VS Code. Then I downloaded the latest jdk. I created a project, added a *.g4 file, wrote a grammar, saved the file and everything worked. BUT! *.java files were generated, but should be *.cs. What did I forget to configure? What needs to be specified so that files are generated for C# and not for Java? Files Here is the code in the .csproj file:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Antlr4.Runtime.Standard" Version="4.13.1" />
  </ItemGroup>

</Project>
