NullReferenceException when launching with default dockpane with burgerbutton

JonasEngedal1 — Wed, 07 Jun 2017 13:16:59 GMT

I have added a Add-in Module project in Visualt Studio with default settings and added a ArcGIS Pro Dockpane with BurgerButton control with default settings - no changes at all. When running the project I get a NullReferenceException before hitting any breakpoints in the code and before ArcGIS Pro has launched. I see the ArcGIS Pro splash screen and then I get the exception in Visual Studio. Adding an ArcGIS Pro Button works.

The error message is: "An unhandled exception of type 'System.NullReferenceException' occurred in mscorlib.dll"

I am using Visual Studio 2015 Update 3 and ArcGIS Pro SDK 1.4.0.7198.

Any ideas?

Best Regards

Jonas

Hi Jonas,

I tried this using ArcGIS Pro 1.4.1 (same build as yours) and VS 2015 Update 3, C# and can't find any problems. Having experienced similar issues in the past I usually traced it to another add-in, in which case removing all add-ins fixed the problem. In a rare case I traced an issue to left-over configuration files (in the Pro / bin folder) that I played with on previous installations of Pro and then forgot to remove before upgrading my Pro version. If you have done anything like this, I recommend to uninstall Pro, check for any left over files, remove them, and then reinstall Pro.

I was actually running ArcGIS Pro 1.4. After updating to 1.4.1 the problem is gone.

Thx.
