Getting Started with the CData ADO.NET Provider for Linear
This guide explains everything you need to work with the CData ADO.NET Provider for Linear. You will learn how to install the provider, set up a connection to your Linear data, and run simple commands in your .NET applications using familiar ADO.NET patterns.
Whether you are building desktop apps, web apps, or background services, the provider enables secure, high-performance connectivity to live Linear data without needing to manage API details manually.
Installation and Licensing
System Requirements
- Windows: Windows 10/11 or Windows Server 2016+
- .NET Versions: .NET Framework 4.0+, .NET 6+, .NET Standard assemblies
- IDE: Visual Studio 2017 or later
Installing the ADO.NET Provider
Windows Installation
- Download the ADO.NET provider installer from your CData account or the evaluation page.
- Run the installer and follow the installation wizard to completion.
- The installer registers the provider and places all assemblies in the appropriate CData installation folders.
-
You will be prompted for your license key during installation:
XXXX-XXXX-XXXX-XXXX-XXXX- Note: If you are using a trial, select Trial Key instead.
Activating your License
Licensing behavior varies depending on whether you are developing with the .NET Framework or .NET Standard. Use the steps below to activate the provider in your environment.
.NET Framework (Windows)
On Windows using the .NET Framework, no extra action is required. The installer or NuGet package automatically installs your development license.
.NET Standard (Windows/Mac/Linux)
For .NET Standard platforms like .NET Core, Mono, or Xamarin, you must install a license manually before using the provider.
Using the Install-License Tool
The toolkit includes an install-license utility in the
lib/netstandard2.0 folder for applying trial or full licenses.
To install a trial license:
dotnet ./install-license.dll
To activate a full product license:
dotnet ./install-license.dll
After running the tool, your development machine is licensed and ready to use the provider in .NET applications.
Runtime Licensing
When deploying applications, specify the Runtime Key (RTK) in your connection string to enable redistribution.
| Property | Description |
|---|---|
| RTK | Your Runtime Key used for deployed ADO.NET applications. |
Common Licensing Questions
Can I use my license on multiple machines?
Yes, depending on your subscription tier. If unsure, review your order confirmation or contact [email protected].
I lost my license key. How do I retrieve it?
Email [email protected] with your order number.
Can I transfer my license to another machine?
Submit a License Transfer Request:

Once approved, an activation is added to your product key and the previous installation becomes invalid.

Connection Configuration
Once installed, the next step is to configure a connection to Linear. Connections are created using ADO.NET connection strings in your .NET application's code or configuration file.
Creating a connection manager
- Open Visual Studio.
- Navigate to View, select Server Explorer.
-
Click Connect to Database from the left sidebar.
- In the Add Connection dialog, click Change.
-
Choose CData Linear data source, then click OK.
Configuring Connection Properties
You can authenticate to Linear with a personal API key or with OAuth 2.0. The API key is the simplest option for connecting with your own Linear account.
Authenticating with an API Key
Set the following connection properties:
- AuthScheme: Set this to APIKey.
- APIKey: A Linear personal API key.
To create a personal API key, log in to Linear, open Settings > Security & access > Personal API keys, select New API key, and create it. Copy the key immediately, because Linear shows it only once.
Authenticating with OAuth
OAuth requires a custom OAuth application registered in Linear (Settings > API > OAuth applications), which provides the OAuthClientId and OAuthClientSecret. Two flows are supported:
- Authorization code: Set AuthScheme to OAuth, InitiateOAuth to GETANDREFRESH, and provide OAuthClientId, OAuthClientSecret, and the CallbackURL defined in your application (e.g., http://localhost:33333). The driver opens Linear in your browser so you can grant access.
- Client credentials: Set AuthScheme to OAuthClient and provide OAuthClientId and OAuthClientSecret. This authenticates the application itself, with no browser interaction, and suits machine-to-machine integrations.
By default, the driver requests the read,write scopes. The driver refreshes the access token automatically when it expires.
Test your connection
- Click Test Connection.
- Once the connection is successful, you can explore the data inside Visual Studio.
Common Connection Issues
Authentication Failed
Solution: Verify OAuth settings, client IDs, secrets, or token permissions for your Linear. Contact [email protected] for assistance.
Cannot Reach Server
Solution: Check firewall, proxy, and VPN configurations. Contact [email protected] for required port information.
Table Not Found
Solution: Confirm you selected the correct schema or database when querying Linear.
