I want to add a new function to my dotnet-isolated (net8.0)
function app project using Azure Functions Core Tools, but I'm getting the following error:
Intialize function app project:
func init --worker-runtime dotnet-isolated --target-framework net8.0 --docker
Add new function:
func new --language c# --template "Timer trigger" --name UpdateApplications
Selected language doesn't match worker set in local.settings.json.Selected worker is: dotnetIsolated and selected language is: dotnet
How can I add new C# functions to my function app?
To add a new function, remove --language c#
in the command func new --language c# --template "Timer trigger" --name UpdateApplications
.
I have created the Timer Trigger .NET 8.0 isolated Azure function using below commands:
1. func init --worker-runtime dotnet-isolated --target-framework net8.0 --docker
2. func new --template "Timer trigger" --name UpdateApplications
local.settings.json:
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated"
}
}
UpdateApplications.cs:
public class UpdateApplications
{
private readonly ILogger _logger;
public UpdateApplications(ILoggerFactory loggerFactory)
{
_logger = loggerFactory.CreateLogger<UpdateApplications>();
}
[Function("UpdateApplications")]
public void Run([TimerTrigger("0 */5 * * * *")] TimerInfo myTimer)
{
_logger.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
if (myTimer.ScheduleStatus is not null)
{
_logger.LogInformation($"Next timer schedule at: {myTimer.ScheduleStatus.Next}");
}
}
}
Program.cs:
var host = new HostBuilder()
.ConfigureFunctionsWebApplication()
.ConfigureServices(services => {
services.AddApplicationInsightsTelemetryWorkerService();
services.ConfigureFunctionsApplicationInsights();
})
.Build();
host.Run();
Response:
Functions:
UpdateApplications: timerTrigger
