1. Introduction

TDengine.Connector is the C# language connector provided by TDengine. C# developers can use it to develop C# application software that accesses TDengine cluster data.

2. Documentation

• To use C# connector, please check Developer Guide, which includes how an application can introduce the TDengine.Connector, as well as examples of data writing, querying, schemaless writing, parameter binding, and data subscription.
• For other reference information, please check Reference Manual, which includes version history, data types, example programs, API descriptions, and FAQs.
• This quick guide is mainly for developers who like to contribute/build/test the C# connector by themselves. To learn about TDengine, you can visit the official documentation.

3. Prerequisites

• Install .NET SDK
• Nuget Client (optional installation)
• TDengine has been deployed locally. For specific steps, please refer to Deploy TDengine. Please make sure taosd and taosAdapter have been started.

4. Build

1. dotnet restore Restore the project's dependencies.
2. dotnet build --no-restore Build the project.

5. Testing

5.1 Test Execution

1. Before running tests, ensure that the TDengine server is installed and that taosd and taosAdapter are running. The database should be empty.
2. In the project directory, run dotnet test to execute the tests. The tests will connect to the local TDengine server and taosAdapter for testing.
3. If the tests pass, Test Run Successful will be printed. If the tests fail, the failure information Test Run Failed will be printed.

5.2 Test Case Addition

Add test cases in the test directory. Add ADO.NET test cases to test/Data.Tests and client driver test cases to test/Driver.Test/Client. The test cases use the xunit framework.

5.3 Performance Testing

Performance testing is in progress.
