.NET interview questions: - How can we improve performance of .NET?

Below are some common points you can remember. List is endless but I do not want to make it long, so that you can remember important ones.

  • Use string builder for concatenation rather than string when concatenation huge string values.
  • Avoid boxing / unboxing, use generics.
  • Avoid writing in line SQL queries use stored procedures.
  • Choose your indexes (clustered and non-clustered) properly.¬†
  • Use Caching for data which will not change frequently.
  • In ASP.NET use output cache directive for page level caching.
