I need a way to write to Windows' event viewer in my app that's using dnx. But, the EventLog class isn't available in the System.Diagnostics namespace so I'm stuck. Is there any other way to write to the EventViewer?
Add from NuGet Microsoft.Extensions.Logging.EventLog Version 2.1.1
CM> Install-Package Microsoft.Extensions.Logging.EventLog -Version 2.1.1
Include the namespace Microsoft.Extensions.Logging.EventLog in the Program.cs file
This resolved my problem.
Good news! EventLog is already ported to corefx and will be available in .NET Core 2.1.
Right now you can download a preview package System.Diagnostics.EventLog from their MyGet feed.
it is available in 2.0 but you have to install the compatibility pack. https://github.com/dotnet/corefx/issues/25440
