Answer
ASP.NET Core enforces request size limits, form limits, upload limits, and aborts oversized bodies. It uses streamed reading to avoid memory spikes.
Quick Answer
ASP.NET Core limits request body size via IIS (maxAllowedContentLength), Kestrel (MaxRequestBodySize), and the request body reading limits. By default, Kestrel limits request bodies to 30MB. You can reduce this per-action with [RequestSizeLimit(1000000)] or disable the limit for file upload endpoints that need it.
