Inline if conditionals in dotnet new template

I have a class like the following:

public class MyTemplateClass : BaseClass {

public class MyTemplateClass : BaseClass {

I want to add a parameter to the template to make the class inherit a specific interface. If I do this using:

public class MyTemplateClass : BaseClass
#if (useInterface)
        , MyInterface
#endif
    {

public class MyTemplateClass : BaseClass
#if (useInterface)
        , MyInterface
#endif
    {

Then the outputted code would be:

public class MyTemplateClass : BaseClass
        , MyInterface
    {

public class MyTemplateClass : BaseClass
        , MyInterface
    {

Which we can all probably agree on does not look that great Is there a way to inline these conditionals? For example, something like:

public class MyTemplateClass : BaseClass #if (useInterface) , MyInterface #endif {

public class MyTemplateClass : BaseClass #if (useInterface) , MyInterface #endif {

as a possible work around, can you conditionally include entire different files?

That is a possibility, but how would the naming of the file work not to mention the duplicated code

what about

#if (useInterface)
public class MyTemplateClass : BaseClass, IMyInterface
#else
public class MyTemplateClass : BaseClass
#endif
{

#if (useInterface)
public class MyTemplateClass : BaseClass, IMyInterface
#else
public class MyTemplateClass : BaseClass
#endif
{

That is an amazing solution, I might go with that thanks :catbless:

You can also use partial classes

RuttieOP•3w ago

I did consider that, but I feel like it'd be hell to actually work with

canton7•3w ago

public partial class MyTemplateClass : BaseClass
{

}

#if USE_INTERFACE
partial class MyTemplateClass : IMyInterface { }
#endif

public partial class MyTemplateClass : BaseClass
{

}

#if USE_INTERFACE
partial class MyTemplateClass : IMyInterface { }
#endif

(not that it's any prettier tbh)
