I need my existing ASP.NET 4.5 Web Forms application rebuilt from the current source and set up cleanly in Visual Studio 2015. Once the solution opens and compiles locally, the code must be updated so every file and configuration setting mirrors what is running on the live server. After the rebuild and code alignment, deliver a fully compiling solution and confirm the site runs error-free in a staging environment that replicates production. Please include basic smoke tests so we can verify all pages load, core workflows execute, and no broken links or missing resources remain. When you hand over the project I expect: • A Visual Studio 2015 solution that builds with zero errors or warnings • Updated code and config files identical to the live server version • A brief test report summarising what you compiled, deployed, and validated You will receive the current source package and a copy of the live server files as soon as we start.

I can help with this, We will rebuild your ASP.NET 4.5 Web Forms solution in Visual Studio 2015, align every config and code file to match production, and deliver a zero-error build with smoke tests. We will diff the source package against your live server files first. This catches orphaned references and mismatched connection strings before compilation even starts. A couple of quick things to confirm: 1) Are there any third-party DLLs or NuGet packages the project depends on? 2) Do you have a staging server ready, or should we set one up? 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 your response. Best regards, Faizan

Hello, this is a legacy ASP.NET Web Forms recovery and environment-alignment job, and the real work is usually not the compile itself but finding the drift between source, server files, IIS behavior, and config transforms. I’ve handled production systems where the main risk is hidden environment coupling: missing assemblies, machine-specific settings, unpublished hotfixes, and server-level configuration that never made it back into the solution. I usually structure this in three passes: clean rebuild in Visual Studio 2015, reconciliation against the live server copy, then staging validation with smoke coverage. The closest examples in my background are Enterprise ProxyTool Client App and Dent-Cloud, both of which required disciplined separation between deployed behavior, configuration state, and validation before handoff. For this kind of ASP.NET 4.5 application, I recommend separating solution recovery, config/file diffing, and runtime verification so build issues don’t get mixed with environment issues. That makes it easier to prove whether a failure is code, packaging, or server configuration. I’d start by mapping the solution structure, identifying missing dependencies, and producing a reconciliation checklist against the live server before staging deployment and smoke tests. Clifton

I can rebuild and properly set up your ASP.NET 4.5 Web Forms application in Visual Studio 2015 so it compiles cleanly and matches your live production environment. I will first recreate the full solution structure and ensure it opens without errors in Visual Studio. Then I will align all project files, configurations, and dependencies with the live server version so both environments are fully synchronized. After that, I will set up a staging environment that mirrors production and run full smoke tests to confirm the application works correctly. This includes checking page loads, core workflows, configurations, and ensuring there are no missing resources or broken functionality. I will also clean up build issues, resolve missing references, and make sure the solution is stable, maintainable, and ready for future deployments. Finally, I will deliver a fully compiling Visual Studio 2015 solution along with a short validation report explaining what was fixed, tested, and deployed.
