Hook up application insights manually

Question

I'm using VS for macOS community to develop a asp.net core site and unfortunately theres no "Add Application insights telemetry".

That makes https://learn.microsoft.com/en-us/azure/application-insights/app-insights-asp-net-core kinda not very helpful...

so, how can i hook it up manually?

Answer 1

You can make the changes manually. There are 3 things to be done.

1. Edit your .csproj to bring ApplicationInsights by adding this line.

<PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.2.1" />

2. Modify Program.cs to include a call to UseApplicationInsights() as shown below.

   public static IWebHost BuildWebHost(string[] args) => WebHost.CreateDefaultBuilder(args) .UseStartup<Startup>() .UseApplicationInsights() .Build();

3. Add you instrumentation key - either as a parameter to UseApplicationInsights() above or in appsettings.json

   { "ApplicationInsights": { "InstrumentationKey": "11111111-2222-3333-4444-555555555555" } }

Now run the application, and telemetry will start flowing to Application Insights,

These steps are described in the wiki as well: https://github.com/Microsoft/ApplicationInsights-aspnetcore/wiki/StartingDoc
