Connect to Kintone through the Server Explorer, without writing a single line of C# or VB.NET code, and then drag tables on the dataset designer, and connect data-aware controls like grids, charts and report designers.


Data Features

ADO.NET and Entity Framework Core Support

Connect to Kintone data using standard ADO.NET objects and Entity Framework Core. The data connector uses ADO.NET objects to make it easy to set up a connection.


SQL and LINQ Query Support

Query against Kintone data using most standard SQL syntax including joins queries, functions, and summaries. It also has in-built support for LINQ queries for native .NET data queries.


Batch CRUD Operations

The data connectors support CRUD operations such as inserting, updating and deleting data through Command and DataAdapter objects. You can further optimize network performance by performing batch updates.


Fast Cache with Incremental Updates

With built-in caching you can improve performance by using a local cache database for repeat operations. It also supports incremental updates so that only new or modified records get synced to the cache.



With scaffolding support, the Kintone data connector library can generate model classes and a database context for Entity Framework Core. The scaffolding command can be run from Visual Studio.


Integrate Kintone Data in .NET

While the Kintone .NET C# data connector focuses primarily on connecting and querying, you can use it alongside other .NET Standard and .NET Framework components to do much more.

  • Integrate Kintone data with DataCollection to provide filtering, grouping, and data virtualization to your data-aware controls
  • Import data from Kintone to DataEngine to analyze massive amounts of data in fractions of a second
  • Connect Kintone data to pivot grids & charts, such as FlexPivot, to analyze data visually
  • Create business reports using FlexReport and Kintone for essential business tasks
  • Display sales data from Kintone in a .NET datagrid using the FlexGrid control in desktop, web, or mobile devices
