The .NET DataStore brings the productivity of PowerBuilder to C# development. It provides a pure C# implementation of the DataWindow and other commonly-used PowerBuilder features. A tool is also included to automatically convert existing DataWindows to .NET.

Highly Productive


Easy to Learn - the .NET DataStore provides virtually the same productive approach to programming as PowerBuilder, including non-visual DataWindow APIs (properties, methods and events), data buffers, transaction management, system functions, and SQL programming.


Minimal Coding - developers can accomplish big tasks with few lines of code, and all SQL is defined in the C# POCO model of the DataStore class, which minimizes redundant code.


Automatic Conversion - an automated conversion tool (the DataWindow Converter) generates standard C# POCO models from existing DataWindows including the child DataWindows.

Standard Architecture


Model-Driven - driven by a standard C# POCO model that contains all data-related properties and attributes. There is a strict separation of concerns and no proprietary .SRD format.


Managed Code - 100% managed code so it benefits from the full power of the Common Language Runtime (CLR), such as built-in security, faster performance, and ease of deployment.


.NET Core - compatible with the .NET Core Framework. You can deploy to either Windows or Linux OS running a variety of Web servers or even go serverless.

Open Design

Open Design


Open-Source - all libraries of the .NET DataStore are available in the C# source code form in addition to the compiled NuGet packages.


Any C# IDE - you can maintain your .NET projects in any C# IDE, such as Visual Studio or SnapDevelop.


IList Compatible - the DataStore inherits from a standard .NET list, enabling you to natively integrate with other .NET code and libraries.

C# Programming Features


The .NET DataStore is the most effective technology for PowerBuilder customer to move to the Cloud with an API-enabled architecture.

Getting Started

Download the trial to start developing your first REST API using powerful DataWindow technology. We also recommend you dive deeper by watching the .NET DataStore Training video.


The .NET DataStore is available as part of either PowerBuilder CloudPro or RapidSharp.

PowerBuilder CloudPro

Deploy existing client/server applications to the Cloud with a C# REST API architecture. The absolute fastest path to the Cloud!



Migrate existing client/server applications to pure C# with any UI technology. Why rewrite when you can automatically port?
