kamsar/kamsar.webconsole

A .NET library to assist in creating pages to host long running operations in a "console" window

Kamsar.WebConsole

This library is designed to provide a framework to execute long-running web requests in, such as search index rebuilds, database backups, etc.

There are three primary components:

• A progress bar that displays task progress
• A "progress status" text that displays the current state of the progress bar in text
• A virtual console window where you can write detailed information about the task. The console auto-scrolls.

Quick Installation/Usage

• Build Kamsar.WebConsole or add the project to your solution
• Create a new Web Form and change its codebehind to inherit from WebConsolePage
• Implement required abstract methods
• During execution of your Process() method, utilize the status updating methods (SetProgress, SetProgressStatus, and WriteConsole/WriteConsoleLine) to follow what you're doing.
• The page will update status in real-time as your processing runs
• Note: any controls, markup, or content in the .aspx page will be ignored; the console takes over the rendering process. Only the @Page line is needed.

See also the Kamsar.WebConsole.Samples project for an example of implementation.

kamsar.webconsole's Issues

When remote host closes connection - ASP.NET process is terminated

When doing a Unicorn sync - we are seeing this error at WebConsole, which kills our application.
Is it possible to avoid terminating ASP.NET process in this case?

ERROR Unhandled exception detected. The ASP.NET worker process will be terminated. 
Exception: System.NullReferenceException
Message: Object reference not set to an instance of an object.
