Azure function v2 engine does not support calls to System.Drawing.Bitmap class. I understand that this limitation has been documented under https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox
I find System.Drawing.Bitmap very useful when it comes to reading image files. Our current product (on .NET Framework) relies on System.Drawing for image processing and works very well. However we are unable to port to Azure because of the sandbox restrictions.
I request the team to consider this support in future versions of the runtime.6 votes
My suspicion is that we will not do this. As you mentioned, the sandbox explicitly blocks calls like this. But, we will check to see.
Add support to run the function app using system assigned identity with Package URL where the package exists in storage account. so instead of using SAS, it can use System Assigned identity to run the function from package URL3 votes
Great feedback item. Please keep the votes coming.
I'd like timerTrigger and WEBSITETIMEZONE app setting to work on Function Apps hosted on Linux Service Plans as described in https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-timer#ncrontab-time-zones
I've set WEBSITETIMEZONE app setting to "Eastern Standard Time"; however, it continues to interpret CRON expression as UTC, even after restart of Function App. I expect this works fine on Windows based Service Plans; however, this does not seem to be working on Linux based plans.
See attached pics. CRON is "schedule": "0 30 15 * * 1-5", but triggers at 11:30am EST.3 votes
We are looking into this.
