Azure Function using Dapr Topic Trigger (or Dapr output binding) Won't Build

[bstone2032]

When trying to create an azure function project in Visual Studio that uses the Dapr Topic trigger (or Dapr output binding), the project cannot be built due to reference of a nuget pkg with version greater than or equal to 99.99.99 in a temporary project that gets built automatically. Since the nuget pkg doesn't exist, the build fails. I am aware of the workaround mentioned here: https://github.com/Azure/azure-functions-dapr-extension/blob/master/troubleshooting-guide.md#unable-to-find-package-microsoftazurewebjobsextensionsdapr-with-version-999999

However, since we're looking to use this trigger in a production environment, this workaround isn't suitable for us. I had opened a support ticket through Microsoft already and I was advised to open an issue here as well so the progress on fixing it can be tracked.

Steps to reproduce:

1. Create a new Azure Functions project using the “Azure Functions” project template.
2. Enter project name/location/solution name
3. Select .NET 8.0 Isolated (Long Term Support) for “Functions worker” dropdown, Dapr Topic Trigger for “Function” dropdown and ensure boxes are checked for “Use Azurite for runtime storage account (AzureWebJobsStorage)” and “Enable Docker”
4. Attempt to build solution. Notice that the project build fails with following error: "Unable to find package Microsoft.Azure.WebJobs.Extensions.Dapr with version (>= 99.99.99)

Note this same issue also occurs when you try to use a Dapr output binding.

Any update on this? Our Docker build also fails with the error "Unable to find package Microsoft.Azure.WebJobs.Extensions.Dapr with version (>= 99.99.99)" after upgrading from .net 6 to .net 8 isolated.

This seems to still be occurring with the 1.0.0 version released on March 15th, 2024.

Hi @AzzA-D,

To unblock you, I have created a sample .NET isolated Azure Function with Dapr extension that you can follow. Or please follow the steps below:

1. Create a local-packages Folder:

   • In the root directory, create a folder called local-packages.
   • Copy the Microsoft.Azure.Functions.Extensions.Dapr.Core.99.99.99.nupkg and Microsoft.Azure.WebJobs.Extensions.Dapr.99.99.99.nupkg files into this folder.

2. Create nuget.config:

   • In the root directory of your project, create a nuget.config file with the following contents:

     <?xml version="1.0" encoding="utf-8"?>
     <configuration>
       <packageSources>
         <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
         <add key="nuget.local" value="local-packages" />
       </packageSources>
     </configuration>
     

3. Include nuget.config and local-packages in the Docker Container:

   • Ensure you copy the nuget.config and local-packages into the Docker container. Here is an example from the Dockerfile:

     dotnet publish *.csproj --configfile nuget.config --output /home/site/wwwroot
     

By following these steps, you should be able to successfully build the Docker image. If you have any further questions or run into any issues, please feel free to reach out.

Hi @ASHIQUEMD , are there any plans to create a fix for this issue/work around when using .NET 8 isolated or is this the way we are expected to configure those projects in perpetuity?

[ASHIQUEMD]

@tdorey00, we do have plans to fix this.

Any update on when the fix can be expected?

Hello, we have released new version of Microsoft.Azure.Functions.Worker.Extensions.Dapr 1.0.1 that has fix for this 99.99.99 issue.

Please perform below steps:

1. Update the local repo azure-functions-dapr-extension and build your project dotnet build --configfile nuget.config. This required to remove the dependency of 99.99.99.
2. Start using the Microsoft.Azure.Functions.Worker.Extensions.Dapr >= 1.0.1 in your function project.
