Consider writing the log messages to a fast store initially, then moving them to the slow store later. If you use dependecy injection you could inject the ILogger interface into the constructor like so ILogger<ReportingManager> logger. Instead of implementing a custom static instance, I could use the default implementation from Serilog. For example, the Azure Application Insights provider stores logs in Azure Application Insights.

The LogContext can be used to dynamically add and remove properties from the ambient execution context; for example, all messages written during a transaction might carry the id of that transaction, and so-on. For example, during the processing of a HTTP request, additional context is gained as we progress through the HTTP pipeline such as knowing the identity of the user. Create logs To create logs, use an ILogger<TCategoryName> object from DI. During development, debug-level events might be switched on: Serilog is a third-party, open-source library that integrates nicely with ASP.NET Core and allows developers to easily log-structured event data to the console, to files, and various kinds of log.

The Dependency Injection system provided by .NET will automatically pass in the instance of ILogger that was defined during startup. It supports the same structured logging APIs, and receives log events from the ASP.NET Core framework class libraries, but adds a stack of features that make it a more appealing choice for some kinds of apps and environments. For example, the following two logging calls are functionally equivalent and produce the same log: MyLogEvents.TestItem is the event ID. To ensure that the correlation ID is pushed into every log event we use the following middleware that uses Serilogs LogContext (discussed in more detail later in this article): Log messages should provide a short description of the event. to your account, Serilog (ILogger) fails to log silently in razor pages when using dependency injection, Version with issue: Publishing to Windows app 6.0.101-preview.9.1843, IDE: Microsoft Visual Studio Community 2022 Preview (64-bit) So my question is, how do I pass in Serilog correctly? {ENVIRONMENT}.json files, where the {ENVIRONMENT} placeholder is the environment. console, Application Insights, files or Serilog (an adapter to the Serilog logging abstraction).

To ensure the SourceContext is set correctly, use the ForContext extension: Typically we use appsettings.json for global settings and configure the actual sinks via environment variables in production (since we dont want to use our remote logging services when running locally): When deploying your applications in production, ensure that logging is configured accordingly: Its understood that during the release of a new project you may need additional information to build confidence in the solution or to diagnose any expected teething issues.
