> how to configure Swagger for Azure Functions on .NET 8 in the isolated worker model?
I have configured swagger with .NET 8.0 isolated worker model in Http trigger function.
Must be add below packages in project file
```
<PackageReference Include="Microsoft.Azure.Functions.Worker" Version="1.16.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Http" Version="3.1.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.OpenApi" Version="1.6.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Sdk" Version="1.16.0" />
```
**Function.cs:**
```
public class JobFunction
{
private readonly ILogger<JobFunction> _logger;
public JobFunction(ILogger<JobFunction> logger)
{
_logger = logger;
}
[Function("v1-job-selectAll")]
[OpenApiOperation(operationId: "selectAllJobs", tags: new[] { "TctJob" })]
[OpenApiParameter(name: "agentId", In = ParameterLocation.Query, Required = true, Type = typeof(Guid), Description = "The id of the agent.")]
[OpenApiRequestBody("application/json", typeof(string), Description = "Request body.")]
[OpenApiResponseWithBody(HttpStatusCode.OK, "application/json", typeof(string), Description = "Job list.")]
[OpenApiResponseWithoutBody(HttpStatusCode.BadRequest, Description = "Invalid ID.")]
public HttpResponseData Run(
[HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = "v1/job/selectAll/{agentId}")] HttpRequestData req)
{
_logger.LogInformation("Processing request for job list.");
var response = req.CreateResponse(HttpStatusCode.OK);
response.WriteString("Job list returned.");
return response;
}
}
```
Below packages which i have used.
```
<PropertyGroup>
<TargetFramework>net8.0</TargetFramework>
<AzureFunctionsVersion>v4</AzureFunctionsVersion>
<OutputType>Exe</OutputType>
<ImplicitUsings>enable</ImplicitUsings>
<Nullable>enable</Nullable>
</PropertyGroup>
<ItemGroup>
<FrameworkReference Include="Microsoft.AspNetCore.App" />
<!-- Application Insights isn't enabled by default. See https://aka.ms/AAt8mw4. -->
<!-- <PackageReference Include="Microsoft.ApplicationInsights.WorkerService" Version="2.22.0" /> -->

</ItemGroup>
<ItemGroup>
<None Update="host.json">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
<None Update="local.settings.json">

<CopyToPublishDirectory>Never</CopyToPublishDirectory>
</None>
</ItemGroup>
<ItemGroup>
<Using Include="System.Threading.ExecutionContext" Alias="ExecutionContext" />
</ItemGroup>
</Project>
```
**Program.cs:**
```
using Microsoft.Azure.Functions.Worker.Extensions.OpenApi.Extensions;
using Microsoft.Extensions.Hosting;
var host = new HostBuilder()
.ConfigureFunctionsWebApplication(worker => worker.UseNewtonsoftJson())
.ConfigureOpenApi() // Required for OpenAPI generation
.Build();
host.Run();
```
By using configuration and code able to run the function successfully.
**Output:**
You can use the same method in `Isolated-process` model.
This worked for me.
```csharp
using System;
using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Options;
namespace FunctionApp16
{
public class Function2
{
private readonly ILogger<Function2> _logger;
public Function2(ILogger<Function2> logger)
{
_logger = logger;
}
[Function(nameof(Function2))]
public void Run([BlobTrigger("%StorageContainer:SourceImages%", Connection = "AzureWebJobsStorage")] string message)
{
_logger.LogInformation($"C# Queue trigger function processed: {message}");
}
}
}
```
**`FunctionApp16.csproj`:**
```xml
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>

</ItemGroup>
<ItemGroup>

</ItemGroup>
</Project>
```
**`Program.cs`:**
```csharp
using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
var host = new HostBuilder()
.ConfigureFunctionsWebApplication()
.ConfigureServices(services =>
{
services.AddApplicationInsightsTelemetryWorkerService();
services.ConfigureFunctionsApplicationInsights();
})
.Build();
host.Run();
```
**`local.settings.json`:**
```
