net tcp wcf service access from logic app standard

Question

net tcp wcf service access from logic app standard

Hi,

As the new logic apps standard is based on functions runtime. Is it possible to access a net tcp wcf service hosted onprem from a logic app standard deployed in a vnet connected internal app plan.
I am able to access the net tcp wcf service from within a function app deployed on the internal vnet connected plan.

Regards,
Ujjwal

Here's how I understand the situation. You have a vnet on-premises linked to a vnet in Azure network traffic can flow between them. You have an app inside the on-premises vnet that you want to talk to Logic App contained in the Azure vnet.

The answer is that yes, this is possible with the new plan. Inbound traffic (wcf->logic app) is handled by a private endpoint and vnet integration is used for outbound traffic (logic app -> wcf)

You can read the instructions for how to set this up here: https://learn.microsoft.com/en-us/azure/logic-apps/secure-single-tenant-workflow-virtual-network-private-endpoint

Thanks for the response!

Which connector should I use to make this outbound call from the logic app to the on prem net tcp wcf service.
(This wcf service only has net tcp bindings and not http.)

I missed the detail that you needed a TCP connection. This is currently not possible within Logic Apps. It is something you could do with Functions, and it sounds like you have already looked at the vnet options there. You wouldn't necessarily need to implement everything within the Function App- it could be just a client to talk to your wcf service with the rest of the logic handled by your logic app.
