Using Project Orleans to Build Actor-Based Solutions on the .Net Platform

This article takes a look at Project Orleans, an actor model framework from Microsoft. Version 7 makes it a lot easier to get started with, as it builds on top of the .NET IHost abstraction. This allows us to add it to .NET applications in a simple way. On top of that it abstracts away most of the complicated parts, allowing us to focus on the important stuff, the problems we need to solve.

An Overview of .NET/Mono Runtime Versions, Profiles, and Targeting Packs

The .NET/Mono Framework has never been a single, unified stack and over the years Microsoft and Novell added several new versions to cover Linux, OS X, and mobile devices. With the introduction of Windows 8 and Visual Studio 11 we can expect one, maybe two more. In an attempt to clear up some of the confusion this article reintroduces all of the major profiles and many of the lessor know ones.

Raw Notes from Redmond

During the first week of May InfoQ went to Redmond for an informal meeting to discuss emerging trends. Normally when we go on this sort of fact-finding mission the reporter’s notes are off the record but we asked for permission to publish them as-is. With the exception of removing email addresses and one piece of NDA material, these are the notes shared within our editorial staff.

Making Microsoft Sync Framework work with PostgreSql

Microsoft Sync Framework is used for occasionally connected clients, for peer-peer applications, and other applications where data needs to be synchronized between multiple data stores. While it doesn’t include providers for non-Microsoft databases, the framework makes it easy to add that support. Roopesh Shenoy demonstrates using PostgreSql.

SOA Master Data Management in .NET 4.0

Sharing data among applications in a complex corporate IT environment is unfortunately often reduced to sharing a common database or in some cases a cube. .NET 4.0 introduces a lot of industrialization tools that make the idea of an application independent SOA data repository reachable. This article explores some of those tools, and how they help make SOA data services flexible and non-intrusive.

MicroORM - A Dynamically Typed ORM for VB and C# in about 160 Lines

Using the new DLR features in VB 10 and C# 4 you can build a configuration-free ORM that works well with legacy stored procedures. Though accessed using normal object-dot-property syntax, all the data objects are built at runtime based solely on the information returned by the database. And this is done with no interfaces to define, classes to implement, or data mapping definitions to write.
