.NET Developer (Real Estate ERP Bug Fixing

Our in-house Real Estate ERP, built on ASP.NET / C# (.NET 6 with a mix of legacy .NET Framework services), has started behaving oddly: during lead assignment the wrong user or lead details are being pulled in, and the same logic sometimes blocks us from updating existing leads. I need an experienced .NET developer who can step through the code, trace the root cause, and deliver a clean, tested fix that leaves the rest of the system untouched.

You will have access to the Git repository, SQL Server database, and the API layer that handles lead workflows. I expect you to reproduce the problem, isolate the faulty logic or data mapping, patch it, and prove that:

• Assigning a new lead now links the correct user and preserves the right lead information.
• Updating an existing lead saves accurately and loads without corruption.
• No other modules (reporting, billing, mailer, etc.) regress after the change.

Please use proper debugging tools (Visual Studio, SQL Profiler, Postman or similar) and commit clean, well-commented code that follows our current architecture. Unit or integration tests covering the fixed scenarios are a plus.

If this sounds straightforward to you and you are comfortable with .NET 6, Entity Framework, RESTful APIs, and agile pull-request workflows, let’s get started—I’ll provide branch access and a short functional walkthrough as soon as you accept.
