Service Fabric .Net Framework 4.5.1 and 4.6

Question

After changing the target framework from 4.5.1 to 4.6 the service in Auzure Fail, the local deployment is working.

Do I need to add .Net 4.6 support ? - I'm unable to find where I can see the frameworks available in my cluster in azure.

Thank you

You can use the following ARM template to install .NET 4.6.1. Note that it's dependent on this script (used by Service Profiler). You also can replace it with any other PowerShell script.

The parameter is the base name of the node. So if you have VM0,.. VM5 in your cluster, you should set vmName = 'VM'. The vmExtensionLoop is set to 5 nodes; you can also change that of course.

If you use an ARM template to deploy your cluster, you can include this as part of it. Note it can slow down the deployment of the scale set, since it requires a restart.

.NET 4.6 is not yet available in the default Windows Server 2012 image used in Azure. At this point, your only option is to log into each VM and install it.
