在服务结构中登录时，NService总线访问被拒绝

Question

I have an issue that has come up out of nowhere in NServiceBus

System.UnauthorizedAccessException
  HResult=0x80070005
  Message=Access to the path 'd:\SfDevCluster\Data\_App\_Node_0\PATH\.diagnostics' is denied.

How can I set the permissions to allow the log file to be created?

I have never had this issue before, no idea why it has suddenly started

I dont even want logging really, so I am happy to just disable it, I just any solution to get round this error as I need to get on with other stuff

I have tried the logic below to disable logging but it has not made any difference

This is called BEFORE I start up my end point

var config = new LoggingConfiguration();
NLog.LogManager.Configuration = config;
NServiceBus.Logging.LogManager.Use<NLogFactory>();

This is happening on a local 1 node dev cluster. It looks like this is being run under network service account. This user has full permissions

Cheers

This happens because your application does not have permission to write in the folder d:\\SfDevCluster\\Data\\_App\\_Node_0\\PATH\\.diagnostics

You should configure the logger to use your application work directory for storing thse logs, take a look on this other SO question: NServiceBus endpoint is not starting on Azure Service Fabric local cluster

Keep in mind, that the folder is temporary and can be deleted at any point when you service is removed from the node.
