Today I wanted to generate a bit of rather trivial C# code to provide a convenient facade to an internal library. After creating a T4 template, loading the required assembly and adding some namespace imports, I found it rather inefficient to write code in that simple text editor without IntelliSense. So of course, there is always the option to write a code generator class with a method that returns a string. The T4 template can instantiate that class, call the method and emit the value directly:

<#= new CodeGenerator().Generate() #>

Next comes the question of how to implement the generator. StringBuilder? Come on, there must be a better way. I checked in another library that I knew was using code generation. Then I saw that the library was using CodeDOM. For my simple needs, I decided that this would be sufficient for the time being (and efficient, since I didn’t want to spend too much time there).

But then I started to wonder. Will CodeDOM still work with the new .NET Core?
