What's New in VS 2012 & .NET Framework 4.5 RC

Hi Folks,

This post is my first blog post after i got back from my vacation in Egypt and getting married! I had a wonderful summer time with my family and here we go back to .NET life style!

After i installed VS 2012 RC on my Development VM and then started to play around with the new IDE. Here are what is called fascinating in the new VS 2012 RC & the framework 4.5.

1) Portable Class Libraries: Now you can develop portable class libraries that can be used to target different framework ranging from .NET framework, Silverlight and Windows Phone 7 or even XBOX 360!!.



Even this is a great option in VS 2012 but please note that also you don't have an option to add references that are not compatible with targeted frameworks.

For example, if you tired to add a .NET framework assembly in portable class library you will find very few assemblies are available, check out below screen shot.


Note: If you tried to add any references that is not compatible with your targeted platforms then VS 2012 will warn you with incompatibility warning!

2) Asynchronous File I/O
Now you can develop code for intensive I/O operations without blocking the main thread!. with that being said, new keywords in C# and VB.NET have been added and supported by the compiler through using async and await keywords which are available in C# and VB.NET.


public async Task CopyFilesAsync(StreamReader Source, StreamWriter Destination)
{
    char[] buffer = new char[0x1000];
    int numRead;
    while ((numRead = await Source.ReadAsync(buffer, 0, buffer.Length)) != 0)
    {
        await Destination.WriteAsync(buffer, 0, numRead);
    }
}

5) Enhancements in Windows Workflow Foundation (WF).
