# C# Azure Functions

How to enable error reporting and monitoring for Azure Functions (serverless)

## Adding RevDeBug NuGet packages

First, add a RevDeBug NuGet repository:

* <https://nexus.revdebug.com/repository/nuget/>

Please refer to detailed instructions on the main [C# manual page](/revdebug/supported-langauges/c.md#adding-revdebug-dependency).

For Azure Function project install two NuGet packages:

* RevDeBug.Net.Compilers.Toolset
* RevDeBugAPM.Agent.AzureFunction

Configure the RevDeBug build time connection as described on the main [C# manual page](/revdebug/supported-langauges/c.md#configure-the-connection-to-revdebug-monitor).

## Setting the RevDeBug recording server address and service name

Using the Azure Portal set two environment variables (application settings) for Azure Functions:

* `SKYWALKING__SERVICENAME` - set to your Function Name
* `SKYWALKING__TRANSPORT__GRPC__SERVERS` - set to address of RevDeBug server instance with 11800 port number appended at the end, eg. `revdebug.server.name:11800`
