Stream analytics: C# udf function not found in azure

Question

Hi,

I'm creating a stream analytics job with a function, which didn't work. Next I followed this tutorial: https://learn.microsoft.com/en-us/azure/stream-analytics/stream-analytics-edge-csharp-udf. It runs on my local pc, but when I test it in Azure I get the following error: Function 'asaapplication2_class1_squarefunction' is unknown (my namespace is asaapplication2). What causes the issue? I literally followed the tutorial step by step.

Thanks,

Filip

Hi anonymous user,

Welcome to Microsoft Q&A and thanks for your query.

Currently you can only test C# UDF in visual studio and testing it in Azure portal is not supported yet. Hence you are seeing Function unknown error.
But you should be able test in Visual studio and publish to Azure and start using your job without issue. It should run fine in Azure.

I have provided a feedback to Azure Stream Analytics product team to improve the error message for user when they try to test C# UDF in portal and also to add a note in documentation about the same. Hopefully the documentation should be updated soon. Will let you know once the doc changes are reflected.

Hope the above info helps.

Thanks for the answer, it helped me to get to the real error. But is it possible numbers are not supported in variable names in C# UDF? My function is falling on this now.
