C# Futures: Closure Annotations

by Jonathan Allen on  May 04, 2015 2

Though on the “Some Interest” list, the next proposal is very controversial. The basic premise for the Lambda Capture Lists proposal is that it would allow more control over how variables are captured in closures.

Code Aware Libraries with Roslyn

Code Aware Libraries are “libraries that provide guidance on correct use through embedded tooling and operates on the user’s code in real time.”

C# Futures: Extension Properties and More

by Jonathan Allen on  May 01, 2015

The next proposal in our C# Futures series considers the possibility of offering extension fields. This in turn would allow for extension properties and extension events.

C# Futures: Asynchronous Sequences

by Jonathan Allen on  Apr 30, 2015

The async/await syntax in C# was well received, but now developers are asking for more. Specifically, they want to be able to return more than one value from their asynchronous function using a “yield return” like syntax. This capability is being referred to as “asynchronous sequences” in a new proposal for C# 7.

Introducing F# 4.0

by Jonathan Allen on  Apr 30, 2015

While all of the recent news has been focused on C# and Windows 10, F# isn’t standing still. Along with Visual Studio 2015 RC is the latest version of F# 4.0.

C# Futures: Managed Pointers

by Jonathan Allen on  Apr 29, 2015

A big emphasis for many developers, especially those writing games or working on pure number crunching, is raw performance. One way to get more performance out of C# is to avoid allocating memory without having to copy structs instead. The next proposal shows how C# can expose the CLR managed pointer support to do just that.

C# Futures: Nullability Tracking

by Jonathan Allen on  Apr 28, 2015

Probably the most common error type in .NET is the Null Reference Exception. The root cause of this error is C#’s inability to express the concept of non-nullable references, which in turn makes compiler-enforced null checking it too burdensome. To address this problem, there is a proposal for mandatory and explicitly nullable references.

Visual Basic: Back by Popular Demand

by Jonathan Allen on  Apr 27, 2015 18

Once again, Visual Basic has been brought back from the brink of deprecation. Reversing a previous decision, VB will be fully supported in ASP.NET 5 including cross-platform.

C# Futures: Tuples and Anonymous Structs

by Jonathan Allen on  Apr 27, 2015 2

With C#6 nearing completion, plans are already being laid for C# 7. While nothing is definite yet, they are starting to categorize proposals in terms of “interest and estimated plausibility”. In this series, we’ll be looking at some of the proposals starting with language support for tuples.

Microsoft Introduces LLILC, LLVM-based .NET/CoreCLR Compiler

by Sergio De Simone on  Apr 21, 2015

The .NET Foundation has announced the release of a new project called LLILC (pronounced "lilac"). The project, initiallycontributed by Microsoft, aims to provide a new LLVM-based native code compiler for .NET Core which will make it possible to run .NET programs "on any platform that CoreCLR can be ported to and that LLVM will target."

Package Management for Python Tools for Visual Studio

by Jonathan Allen on  Apr 02, 2015

Package Management for Python Tools for Visual Studio Microsoft is continuing its efforts to support Python in Visual Studio. Still in beta, Python Tools for Visual Studio 2.2 (PTVS) brings more of the standard features found in other VS supported languages such as C# and VB including code snippets, an auto watch window, and package management.

True Windows File System Access with AlphaFS 2.0

by Jonathan Allen on  Mar 13, 2015

A major limitation of the .NET framework is its inability to truly work with the Windows file system. Even seemingly basic operations such as working file paths longer than 260 characters long is beyond the capabilities of System.IO. This is where AlphaFS comes into play.

Pooled Memory Streams for .NET

by Jonathan Allen on  Mar 09, 2015

Like most languages that rely on a mark-and-sweep garbage collector, C# can run into performance problems when allocating memory too often or when making large allocations. Ben Watson, a Senior SDE at Microsoft working on Bing, ran into just that problem with the MemoryStream class.
