vs2017 multiple projects but debug work only on startup proj

raven daniel

Hi all, i need serious help

In my solution i have 37 projects, mostly windows projects, in VB and C#, web services etc.
1) on solution properties -> Configuration Properties
Everything is set to debug, and build option is ticked.

2) i have my login project VB set to start up - which debugs, and hits all break points.

3) my other VB projects also hit break points.
4) projects are reference using project reference.
5) All projects have been cleaned, and build individually with no errors.
6) My Debug -> options -> General:
Enable just my code - true
Enable .net frame source stepping - false
Break al processes when one process breaks - true
Enable javascript debugging for asp.net - true
7) on project settings -> Enable native code debugging - true

But my C# project does not hit any break points, and this is where im i have to debug right now, cause i cant progress in my work otherwise.

The symbols are a solid red, stated loaded.

I cant figure out what else is wrong. Please help

Thanks for the help, i have found my solution.
I set "use native debugging" to false on both vb start up login project and my C# project.
Then i set to true "Use managed Compatibility Mode" which can be found under

Menu -> Debug -> Option -> Debugging/ General.

This allowed me to debug both VB and C#. Hope it helps someone out there.

P.S not sure how to set my reply as the answer

Hey raven

As you said your c# project is a class library, so it cannot be your startup project.

Just try to remove that project from your solution and add it again and then take reference of it into your project.

May be that works. Also have a look to the below links answer

i dont have any json files in the solution directory or in the directory of the 37 projects.
I did a search, i also went through most project and configuration files in notepad to look for anything that states "native"

@AmitGupta

so in my VB login project i reference -> add reference -> project tab -> select project

so looking at the path, this is using the C# .dll in the C# directory of the project

un fortunately i cant set the C# as startup as it wont run correctly it relies on the login VB project to execute first.

"A project with an Output Type of Class Library cannot be started directly. In order to debug this project, add an executable project to this solution and set it as the start up project"

hi try below

In the lauchsettings.json file, add the following property:

C#
"nativeDebugging": true

So, for example, your file might look like the following:

C#

{ "profiles": { "Mixed_Mode_Calling_App": { "commandName": "Project", "nativeDebugging": true } } }

1. In your vb project, how you are calling the c# project (did you took reference or calling the executable). Not sure but this might be a problem. 2. Try to set the startup prohect as your c# and check if it was holding your breakpoints.

@Laxmidhar
as mentioned
"7) on project settings -> Enable native code debugging - true"

My native project is VB where native code debugging is set to true.
my C# project native code debugging i am also trying in true.

still nothing. Yes i am trying to configure for a mix mode here. but i am stuck.
as the native code debugging is set to true but no break points are being hit in my C# project.
