  • 0

I got a book named “Pro C# 2005 and the .NET 2.0 Platform, Third Edition by Andrew Troelsen”.
I am wondering whether I should buy the “Pro C# 2010 and the .NET 4 Platform, Fifth Edition” instead. Since, the latest version of .NET is 4.0. If I learn C# based on this old book, do I miss some critical parts of the C# language? Or, I can start with this book and learn new .NET 4.0 features with other resources.

Thank you

    You can start with that book and learn C# 4.0 from elsewhere. This is what’s been added after C# 2.0:

    C# 3.0:

    • LINQ
    • lambdas
    • extension methods
    • expression trees
    • anonymous types
    • local type inferencing
    • automatic properties
    • object initializers
    • collection initializers
    • partial methods

    C# 4.0

    • dynamic member lookup
    • covariant and contravariant generic type parameters
    • optional parameters and named arguments
    • parallelization framework (actually part of .NET 4, not C# 4.0 per se)
