Template 10 – Error CS0234 The type or namespace name ‘ApplicationInsights’ does not exist

Windows-Dev

Template 10 is set of Visual Studio templates for Windows 10 UWP C# and XAML applications. For those who are interested there is a whole course about Template 10 on the Microsoft Virtual Academy site.

Once you have installed Template 10 via NuGet you will find that your project fails to build with the following error:

Error CS0234 The type or namespace name ‘ApplicationInsights’ does not exist in the namespace ‘Microsoft’ (are you missing an assembly reference?)

The solution is to add the following references to ApplicationInsights in project.json dependencies:

	"Microsoft.ApplicationInsights.PersistenceChannel": "1.0.0",
	"Microsoft.ApplicationInsights": "1.0.0", 
	"Microsoft.ApplicationInsights.WindowsApps": "1.0.0",

You should then be able to build and run your Template 10 project.

The full project.json is as follows:

{
  "dependencies": {
    "Microsoft.NETCore.UniversalWindowsPlatform": "5.1.0",
	"Microsoft.ApplicationInsights.PersistenceChannel": "1.0.0",
	"Microsoft.ApplicationInsights": "1.0.0", 
	"Microsoft.ApplicationInsights.WindowsApps": "1.0.0", 
    "Microsoft.Xaml.Behaviors.Uwp.Managed": "1.1.0",
    "Newtonsoft.Json": "8.0.3",
    "Template10": "1.1.*"
  },
  "frameworks": {
    "uap10.0": {}
  },
  "runtimes": {
    "win10-arm": {},
    "win10-arm-aot": {},
    "win10-x86": {},
    "win10-x86-aot": {},
    "win10-x64": {},
    "win10-x64-aot": {}
  }
}
