Incorrect collapse of expression bodied member with compiler directive

[lonix1]

I'm unsure which repo this belong in?

This collapses properly:

public class Demo1 {

  public int Foo() {
    return
    #if DEBUG
    10;
    #else
    20;
    #endif
  }

}

This does not:

public class Demo2 {

  public int Foo() =>
    #if DEBUG
    10;
    #else
    20;
    #endif

}

Can you clarify what you mean by "incorrect collapse"?

[lonix1]

One expects this:

public class Demo1 {

>  public int Foo() {

}

But it does this:

public class Demo2 {

>  public int Foo() =>
    #else
    20; ...

}

And I've seen this too:

public class Demo2 {

>  public int Foo() =>
    #endif

}

You can see for yourself by copy-pasting into a c# file.

We'd take a targeted community fix here. Moving to backlog.
