How to modify SpecFlow code generation behaviour

We have a feature file with 15061 lines ( auto-generated through another system ). Specflow (version 3.9.7) manages to generate a cs file through MSbuild task with 39017 lines. However build of the generated feature file fails with Stack overflow error as:

C:\Program Files\dotnet\sdk\6.0.202\Roslyn\Microsoft.CSharp.Core.targets(75,5): error : Stack overflow. [D:\Code\DDS_SpecFlow\DDS_SpecFlow.csproj]
C:\Program Files\dotnet\sdk\6.0.202\Roslyn\Microsoft.CSharp.Core.targets(75,5): error : Repeat 24214 times: [D:\Code\DDS_SpecFlow\DDS_SpecFlow.csproj]
C:\Program Files\dotnet\sdk\6.0.202\Roslyn\Microsoft.CSharp.Core.targets(75,5): error : -------------------------------- [D:\Code\DDS_SpecFlow\DDS_SpecFlow.csproj]
C:\Program Files\dotnet\sdk\6.0.202\Roslyn\Microsoft.CSharp.Core.targets(75,5): error :    at Microsoft.CodeAnalysis.CSharp.Syntax.InternalSyntax.DirectiveStack.CompleteRegion(Roslyn.Utilities.ConsList`1<Microsoft.CodeAnalysis.CSharp.Syntax.InternalSyntax.Directive>) [D:\Code\DDS_SpecFlow\DDS_SpecFlow.csproj]
C:\Program Files\dotnet\sdk\6.0.202\Roslyn\Microsoft.CSharp.Core.targets(75,5): error : -------------------------------- [D:\Code\DDS_SpecFlow\DDS_SpecFlow.csproj]

Seems like the number of #line directives generated in the file is more than the compiler can handle, since the build succeeds once I remove all of the line directives.

So I am looking a way to configure the SpecFlow code generation task and skip line directive generation.

Please split your feature files into multiple files. Any file with 15k lines is unreadable and unmaintainable.

Seb Rose wrote a good article on how to organize your feature files at https://cucumber.io/blog/bdd/solving-how-to-organise-feature-files/
