T4 templates can be used to auto-generate code, such as creating TypeScript types from C# class/enums. Remove the manual step by automatically running your templates as part of the build process.
In Visual Studio, a T4 text template is a mixture of text blocks and control logic that can generate a text file. The control logic is written as fragments of program code in Visual C# or Visual Basic.
The generated file can be text of any kind, such as a web page, or a resource file, or program source code in any language.

This is great, but requiring manual intervention for code generation is so 2019.

Run your T4 Text Transforms after the C# code builds:
BackEnd.csproj1<PropertyGroup>2 <PostBuildEvent>"$(SolutionDir)packages\Mono.TextTransform.1.0.0\tools\TextTransform.exe" "$(ProjectDir)Models\Model.tt" -a=outDir!"$(TargetDir)$(ConfigurationName)\"</PostBuildEvent>3</PropertyGroup>
If you need to run your T4 template before the build, such as for T4 MVC, you'll want to use a
<PreBuildEvent> instead of the
<PostBuildEvent> above in your
