I am looking for some good resource such as excellent articles/PDFs/PPTs/Whitepapers on Performance improvement techniques for SQL server, C#, ASP.NET, WCF and .NET. They should be teach me with PRACTICAL examples.
The trace tools and how to use them efficiently would be greatful.
Please do provide them if you REALLY use them in your day to day activity.
Please do avoid simply googling and sending the link.
