Hello there, I will fix the existing bugs and implement the new features in your WPF desktop application — ensuring the UI and underlying logic work correctly together. One thing I will review early is your MVVM binding structure — broken bindings are a common source of silent WPF bugs that do not throw exceptions but cause UI elements to stop updating. Catching these first often resolves multiple issues at once. Questions: 1) Which bugs are you seeing — UI rendering issues, data handling, or crashes? 2) What features need to be added? Looking forward to discussing further. Best regards, Kamran

Hi there, I understand you need an experienced C#/.NET developer to continue a partially completed WPF desktop application, fix existing bugs, and add a few small features within a modest project scope. I have solid experience with C#, .NET, WPF, XAML, MVVM patterns, desktop UI debugging, data binding issues, and improving partially built applications without disrupting existing code. I would review the current project, reproduce and fix the reported bugs, implement the requested features cleanly, test the final build, and provide a short summary of all changes made. Q1: Can you share the current WPF source code and list of known bugs? Q2: Which .NET version is the application using? Q3: What new features need to be added first? Best regards.

I'm a C#/.NET developer and your brief reads like a classic "partially built WPF app that needs a steady second pair of hands." Two things jump out: the work splits into bug fixes plus a few new features, and there's a SQL Server backend in the mix. Week one I'd ship the bug fixes first so you see momentum before we touch new features. Here's how I'd run it: 1. Triage call where you list the bugs and the features, and I tag each one by effort and risk. 2. Fix the bugs in priority order, each as a small, testable change against your existing data layer. 3. Build the new features behind the same patterns already in your codebase, so nothing feels bolted on. I've shipped production C#/.NET and SQL-backed software for years, including data-heavy apps where a wrong query or a null edge case breaks the UI. WPF binding and SQL Server are exactly that kind of careful work. $162 over 7 days fits a small, well-scoped batch like this. Done = every listed bug closed and the new features working against your real database, handed back with a short note on what changed. To scope it right: can you send the bug list and a one-line description of each feature, or would you rather walk me through the app on a quick call first? P.S. If the app talks to SQL Server directly from the UI thread, that's often the real cause of freezes that look like "bugs." I'd check that early. Waqar

Hello there, We will fix the existing bugs in your WPF app and implement the remaining features on your current codebase. Our first step will be a quick audit of the XAML bindings and view models. Broken bindings are the most common silent issue in WPF apps, and catching those early prevents rework later. A couple of quick things to confirm: 1) Which .NET version is the project targeting (.NET Framework or .NET 6+)? 2) Are the bugs documented, or should we start with a full review? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to potentially working together. Thanks, Faizan

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I have experience handling similar WPF desktop applications and I'm available to start your project right now. I bring deep expertise in C#, .NET, WPF, .NET Core, .NET 5/6, Microsoft SQL Server, and Desktop Application Development with over 10 years of experience. One of the key challenges in projects like this is fixing bugs and adding new features without affecting the existing WPF structure, UI bindings, database logic, or current application flow. I can first review the partially completed codebase, identify the issues, then complete the required fixes and features in a clean, stable way. I have a couple of quick questions. • Is the application using MVVM architecture? • Are the remaining issues mainly UI-related, database-related, or application logic bugs? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos
