There is no such restriction in providing a certain class name for Azure function. It accepts all the class names including **Workflows** and **WorkflowTemplates** too.
- For testing purpose, I have below code in ***`Workflows.cs`*** class.
```csharp using Microsoft.AspNetCore.Http; using Microsoft.AspNetCore.Mvc; using Microsoft.Azure.Functions.Worker; using Microsoft.Extensions.Logging; using System.Net;
namespace _78470050 { public class Workflows { private readonly ILogger<Workflows> _logger;
public Workflows(ILogger<Workflows> logger) { _logger = logger; }
[Function("GetWorkflows")] [ProducesResponseType(typeof(IEnumerable<Workflow>), (int)HttpStatusCode.OK)] [ProducesResponseType(typeof(string), (int)HttpStatusCode.BadRequest)] [ProducesResponseType((int)HttpStatusCode.Unauthorized)] public async Task<IActionResult> RunGetWorkflows([HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "Workflows")] HttpRequest req) { return await Middleware.Run(async () => await GetWorkflows(req), req, _logger); }
public static async Task<IActionResult> GetWorkflows(HttpRequest req) { var workflows = new List<Workflow> { new Workflow { Id = 1, Name = "Workflow 1" }, new Workflow { Id = 2, Name = "Workflow 2" }, };
return new OkObjectResult(workflows); } }
public class Workflow { public int Id { get; set; } public string Name { get; set; } }
} ```
**.csproj**-
```csharp <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFramework>net8.0</TargetFramework> <AzureFunctionsVersion>v4</AzureFunctionsVersion> <OutputType>Exe</OutputType> <ImplicitUsings>enable</ImplicitUsings> <Nullable>enable</Nullable> <RootNamespace>_78470050</RootNamespace> </PropertyGroup> <ItemGroup> <FrameworkReference Include="Microsoft.AspNetCore.App" /> <PackageReference Include="Microsoft.Azure.Functions.Worker" Version="1.22.0" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Http" Version="3.1.0" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore" Version="1.2.1" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.Sdk" Version="1.17.3-preview1" /> <PackageReference Include="Microsoft.ApplicationInsights.WorkerService" Version="2.22.0" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.ApplicationInsights" Version="1.2.0" /> </ItemGroup> <ItemGroup> <None Update="host.json"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> </None> <None Update="local.settings.json"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> <CopyToPublishDirectory>Never</CopyToPublishDirectory> </None> </ItemGroup> <ItemGroup> <Using Include="System.Threading.ExecutionContext" Alias="ExecutionContext" /> </ItemGroup> </Project> ```
I am able to get the expected response.

A .Net 8 Isolated Function with Http Trigger and Timer Trigger should have the below packages in its `.csproj` file.
**.csproj**-
```csharp <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFramework>net8.0</TargetFramework> <AzureFunctionsVersion>v4</AzureFunctionsVersion> <OutputType>Exe</OutputType> <ImplicitUsings>enable</ImplicitUsings> <Nullable>enable</Nullable> <RootNamespace>_77832689</RootNamespace> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.Azure.Functions.Worker" Version="1.20.1" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Http" Version="3.1.0" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Timer" Version="4.3.0" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.Sdk" Version="1.16.4" /> <PackageReference Include="Microsoft.ApplicationInsights.WorkerService" Version="2.22.0" /> <PackageReference Include="Microsoft.Azure.Functions.Worker.ApplicationInsights" Version="1.1.0" /> </ItemGroup> <ItemGroup> <None Update="host.json"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> </None> <None Update="local.settings.json"> <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> <CopyToPublishDirectory>Never</CopyToPublishDirectory> </None> </ItemGroup> <ItemGroup> <Using Include="System.Threading.ExecutionContext" Alias="ExecutionContext" /> </ItemGroup> </Project> ```
The package `Microsoft.AspNetCore.App` which you are referring in your .csproj file is been deprecated. But without using this package also your function should work alike me.
I also having a Timer Trigger and Http Trigger function. Here I am not using Startup class, as to execute the mentioned functions, `Program.cs` file is sufficient.
**TimerTriggerFunction.cs**-
```csharp using System; using Microsoft.Azure.Functions.Worker; using Microsoft.Extensions.Logging;
namespace Company.Function { public class TimerTrigger1 { private readonly ILogger _logger; public TimerTrigger1(ILoggerFactory loggerFactory) { _logger = loggerFactory.CreateLogger<TimerTrigger1>(); }
[Function("TimerTriggeredFunction")] 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}"); } } } } ```
**HttpTriggerFunction.cs**-
```csharp using System.Net; using Microsoft.Azure.Functions.Worker; using Microsoft.Azure.Functions.Worker.Http; using Microsoft.Extensions.Logging;
namespace _77832689 { public class HttpTriggeredFunction { private readonly ILogger _logger; public HttpTriggeredFunction(ILoggerFactory loggerFactory) { _logger = loggerFactory.CreateLogger<HttpTriggeredFunction>(); }
[Function("HttpTriggeredFunction")] public HttpResponseData Run([HttpTrigger(AuthorizationLevel.Function, "get", "post")] HttpRequestData req) { _logger.LogInformation("C# HTTP trigger function processed a request.");
var response = req.CreateResponse(HttpStatusCode.OK); response.Headers.Add("Content-Type", "text/plain; charset=utf-8");
response.WriteString("Welcome to Azure Functions!");
return response; } } } ```
**Program.cs**-
```csharp using Microsoft.Azure.Functions.Worker; using Microsoft.Extensions.Hosting; using Microsoft.Extensions.DependencyInjection;
var host = new HostBuilder() .ConfigureFunctionsWorkerDefaults() .ConfigureServices(services => { services.AddApplicationInsightsTelemetryWorkerService(); services.ConfigureFunctionsApplicationInsights(); }) .Build();
host.Run(); ```
**local.settings.json**-
```json { "IsEncrypted": false, "Values": { "AzureWebJobsStorage": "UseDevelopmentStorage=true", "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated" } } ```
Having all these configurations in place, I am able to get the expected response.
