How to connect C# to Salesforce via ADO.NET
Summary
This article explains how to integrate Salesforce data into C# applications using ADO.NET with the dotConnect for Salesforce provider. It addresses complexities common in REST API integrations by offering a straightforward, SQL-like querying experience familiar to .NET developers. The article walks through setup steps including installation, security token acquisition, package management, connection string configuration, and executing queries with examples. It enables Salesforce teams to build reliable, maintainable integrations that smoothly transition from sandbox to production environments while supporting advanced ORM features for scalability.
Takeaways
- Use dotConnect for Salesforce to simplify Salesforce data access via ADO.NET.
- Configure connection strings with username, password, security token, and license key.
- Install required NuGet packages: Devart.Data.Salesforce and Devart.Data.SqlShim.
- Query Salesforce objects with SQL-like syntax using SalesforceCommand and SalesforceDataReader.
- Leverage ORM features like LINQ and Entity Framework for complex integration needs.
Salesforce data is critical, but integrating it cleanly into C# applications is rarely straightforward. REST-based approaches often introduce fragmented authentication logic, brittle mappings, and operational overhead that grows with every new integration. That complexity is why many teams still rely on ADO.NET. This data access API remains the most practical workhorse for database-style access in C#, thanks to its connection–command–reader model and predictable behavior. In Salesforce integrations, this model is often implemented through dotConnect for Salesforce , giving .NET applications SQL-like access to Salesforce objects while keeping the surrounding application architecture unchanged. Why dotConnect for Salesforce dotConnect for Salesforce provides a complete ADO.NET provider for Salesforce, handling authentication, metadata mapping, and query translation internally. This lets .
