Windows Service: Managed Compatibility Mode does not support Edit and Continue

Question

I have been assigned to work on a Windows Service project. I installed it in my machine using installer class (ProjectInstaller.cs). I want to debug the source code and sometimes need to make changes while it is in debug mode. I attached the process via Debug menu to debug the project which works fine but it throw an error while I am trying to edit or continue the source code:

Managed Compatibility Mode does not support Edit and Continue

I googled and tried tons of solutions but none of them worked for me, couple of them are as below:

• Unchecked the Use Managed Compatibility Mode from Tools -> Options

• Unchecked Managed Compatibility Mode from Debug -> Attach to Process -> Attached To -> Select...

• Checked the Managed (v4.6, V4.5, V4.0) from Debug -> Attach to Process -> Attached To -> Select...

• Played with Platform target in Project Build.

• Added {351668CC-8477-4fbf-BFE3-5F1006E4DB1F} field in my .csproj file

The error message varies depending on different solutions I implemented.

Below is the link I last time tried:

https://blogs.msdn.microsoft.com/visualstudioalm/2013/10/16/switching-to-managed-compatibility-mode-in-visual-studio-2013/

I am guessing: the last one didn't work because I do not have an exe project for my service instead I have implemented ProjectInstaller.cs Class and manually installed it through command prompt.

Any suggestion/recommendation are welcomed.

Answer 1

Edit and Continue requires many factors which are not obvious to users. Your case is simply not supported (mostly for attaching cases).

See Supported Code Changes (C#) in MSDN. In particular:

Edit and Continue is not available in the following debugging scenarios: [...]

Debugging an application that has Attach to instead of running the application by choosing Start from the Debug menu.

Answer 2

Unckeck Use Managed Compatibility Mode, It working for me! and you must Enable Edit and Continue in Debuging General

Answer 3

Attaching my process for each debug was a headache for me.

Just want to share a link that saved a lot of my time by writing a simple method and calling it in Main() method inside Program.cs.

This also gives me flexibility to edit and continue my code as simple as WinForm / Web Form. LOVE IT.
