I am developping an ArcMap 10.3 Add-In targeting .NET framework 4.5 on Visual Studio 2013. I used ESRI's wizard to build a simple button add-in and the projects debug properties are configured to start the external program "C:\Program Files (x86)\ArcGIS\Desktop10.3\bin\ArcMap.exe".
The add-in ran properly when I started debuggig the Add-In for the first time but I couldn't get the breakpoints to hit. I followed ESRI recommandation "How to debug" on ESRI online help and modified the ArcMap.exe.config file to enable supported runtime 4.0.30319
<!-- <supportedRuntime version="v2.0.50727"/> -->
The next time I started debuggin the Add-In I get an error message from Visual Studio : "Error while trying to run project: Unable to start program 'C:\Program Files (x86)\Desktop10.3\bin\ArcMap.exe'."
This error message comes right after ArcMap's splash screen. The following screenshot is not from the actual Add-in because the splash screen appears and disappears way too fast and I can't get screenshot.
I tried different things but without success :
- build the project using different platforms :"Any CPU" and "x86"
- changed "ArcCatalog.exe.config" file to use the same supported runtime
- restarted computer
- used different supported runtime version: version="v4.0.30319", version="v4.0", version="v4.5"
I dont know what to do next to be able to debug the Add-in. I don't want to develop without this feature!
Any help would be greatly appreciated.
