Hi,

I’m trying to implement Google StackDriver for nlog. I need to set an environment variable for the json file as per documentation: [https://cloud.google.com/docs/authentication/getting-started#windows](https://cloud.google.com/docs/authentication/getting-started#windows)

Is there a good way in Litium to set environment variables?  
The startup seems to be compiled resource, any other ways i see is to use:

1. StartupTask to create a task that reads from web.config or similar.
2. Deployment to set during our CI

Has anyone solved this?

Litium version: 7.2.3

I think you should use the `CredentialFile` or `CredentialJson` target properties to point out the json or inlining the json directly in _nlog.config_ instead of trying to get the environment variable set.

See [https://github.com/googleapis/google-cloud-dotnet/tree/master/apis/Google.Cloud.Logging.NLog/Google.Cloud.Logging.NLog#target-options](https://github.com/googleapis/google-cloud-dotnet/tree/master/apis/Google.Cloud.Logging.NLog/Google.Cloud.Logging.NLog#target-options) for the properties reference.
