A clerk-office team tries to host a Windows-only .NET Framework site on a Linux App Service plan, and the runtime never starts. What create-time decision caused the failure?
Select an answer to reveal the explanation.
Short Explanation
Plan OS is chosen when you buy the engine—not flipped later with a mystery app setting. A Windows-only .NET Framework site needs a Windows plan the way a diesel truck needs diesel. Mismatch the OS and the runtime simply never starts.
Full Explanation
An App Service plan’s operating system is fixed at creation and must align with the application’s supported stack. Windows-only workloads such as classic .NET Framework sites require a Windows plan; Linux plans host cross-platform stacks such as .NET (Core)/ASP.NET Core, Node, Python, and Java. There is no supported WEBSITE_OS toggle that converts a Linux plan into a Windows runtime after the fact.
