About
Crm.Sdk.Core helps .NET developers build applications that work with Microsoft Dynamics CRM, including on-premises CRM 2015.
The project includes two libraries:
• Crm.Sdk.Core — a WCF-based SDK with asynchronous operations.
• Crm.Sdk.Core.Lite — a lightweight SOAP-over-HTTP alternative with familiar SDK namespaces and types, without WCF dependencies.
I'm Maksim, the maintainer. My focus is reliable connections, compatibility with newer .NET versions, automated testing, and clear documentation.
Your contributions help me dedicate more time to maintenance, bug fixes, and improvements. Both libraries remain freely available under the MIT license. Bug reports, documentation improvements, and code contributions are also welcome.
