When CodeNav is set to Sort by Order, some methods that are not part of an interface may be displayed out-of-order

Hello Samir,

This is a follow-up issue for #140.

When CodeNav is set to Sort by Order, some methods that are not part of an interface may be displayed out-of-order.

Repro:

File IMyService.cs:

internal interface IMyService
{
 void PublicMethod1();

 void PublicMethod2();

 void PublicMethod3();
}

File MyService.cs:

namespace SomeNamespace;

internal sealed class MyService : IMyService
{
 private static void PrivateMethod0() // <-- Not part of an interface.
 {
 }

 public void PublicMethod1()
 {
 }

 private static void PrivateMethod1() // <-- Not part of an interface.
 {
 }

 public void PublicMethod2()
 {
 }

 public void PublicMethod3()
 {
 }

 internal void PrivateMethod3() // <-- Not part of an interface.
 {
 }
}

CodeNav displays this:

+---------------------------------+
| SomeNamespace |
+---------------------------------+
| +-----------------------------+ |
| | MyService : IMyService | |
| +-----------------------------+ |
| | PrivateMethod0 () | |
| | +-------------------------+ | |
| | | IMyService | | |
| | +-------------------------+ | |
| | | PublicMethod1 () | | |
| | | PublicMethod2 () | | |
| | | PublicMethod3 () | | |
| | +-------------------------+ | |
| | PrivateMethod1 () | | // <-- Wrong position (must be between 'PublicMethod1' and 'PublicMethod2').
| | PrivateMethod3 () | |
| +-----------------------------+ |
+---------------------------------+

But it should instead display this:

+---------------------------------+
| SomeNamespace |
+---------------------------------+
| +-----------------------------+ |
| | MyService : IMyService | |
| +-----------------------------+ |
| | PrivateMethod0 () | |
| | +-------------------------+ | |
| | | IMyService | | |
| | +-------------------------+ | |
| | | PublicMethod1 () | | |
| | +-------------------------+ | |
| | PrivateMethod1 () | |
| | +-------------------------+ | | // <-- Open interface block each time next method is part of an interface but previous method wasn't.
| | | IMyService | | |
| | +-------------------------+ | |
| | | PublicMethod2 () | | |
| | | PublicMethod3 () | | | // <-- While current method is part of same interface as previous method, stay in same interface block.
| | +-------------------------+ | | // <-- Close interface block if next method is not part of same interface (or it's last method).
| | PrivateMethod3 () | |
| +-----------------------------+ |
+---------------------------------+

Note that if regions are involved, CodeNav display is correct.

Try with this file:

File MyService2.cs:

namespace SomeNamespace;

internal sealed class MyService2 : IMyService
{
 private static void PrivateMethod0() // <-- Not part of an interface.
 {
 }

 #region PublicMethod1

 public void PublicMethod1()
 {
 }

 private static void PrivateMethod1() // <-- Not part of an interface.
 {
 }

 #endregion

 public void PublicMethod2()
 {
 }

 #region PublicMethod3

 public void PublicMethod3()
 {
 }

 internal void PrivateMethod3() // <-- Not part of an interface.
 {

 #endregion
 }
}

CodeNav displays this:

+---------------------------------+
| SomeNamespace |
+---------------------------------+
| +-----------------------------+ |
| | MyService2 : IMyService | |
| +-----------------------------+ |
| | PrivateMethod0 () | |
| | +-------------------------+ | |
| | | #PublicMethod1 | | |
| | +-------------------------+ | |
| | | +---------------------+ | | |
| | | | IMyService | | | |
| | | +---------------------+ | | |
| | | | PublicMethod1 () | | | |
| | | +---------------------+ | | |
| | | PrivateMethod1 () | | |
| | +-------------------------+ | |
| | +-------------------------+ | |
| | | IMyService | | |
| | +-------------------------+ | |
| | | PublicMethod2 () | | |
| | +-------------------------+ | |
| | +-------------------------+ | |
| | | #PublicMethod3 | | |
| | +-------------------------+ | |
| | | +---------------------+ | | |
| | | | IMyService | | | |
| | | +---------------------+ | | |
| | | | PublicMethod3 () | | | |
| | | +---------------------+ | | |
| | | PrivateMethod3 () | | |
| | +-------------------------+ | |
| +-----------------------------+ |
+---------------------------------+

which is correct.

Context:

• CodeNav 10.5.129.
• VS 2026 Insiders [11619.145].

Thanks for reporting!

Starting to wonder if showing implemented interfaces like this is even worth it... 😅

It looks nice but comes with a lot of intricacies like this.
Showing an implemented interface icon on the list item with a name as tooltip would be so much easier...

I'll look into solving this one after the window sync issues.

You're absolutely right!
That's also my opinion.
