In my old project I had this bit of code in its Build.cs:

```
    if (UEBuildConfiguration.bBuildEditor == true)
    {
        PublicDependencyModuleNames.AddRange(
            new string[] {
                "UnrealEd",
            }
        );

```

The goal is to load UnrealEd only if I’m compiling an Editor build configuration (Development Editor, etc).

However when I try to switch to 4.19, I get an error saying:

```
error CS0103: The name 'UEBuildConfiguration' does not exist in the current context

```

So how do you do it in 4.19?

Try this:

```
if (Target.bBuildEditor)
{
	PrivateDependencyModuleNames.Add("UnrealEd");
}
```

Even when question is already answered, i want to point, that better to use this:

`if (Target.Type == TargetRules.TargetType.Editor) {...}`

Could you explain why it’s better?
