Default Behavior When Content-Type Is Not Provided

When Content-Type is not specified, the framework determines Content-Type according to the following priority:

Request content header: If Content-Type is set via WithHeader or similar, it takes precedence.
Automatic content type inference: If no content header is set, the framework automatically infers based on the concrete type of RawContent according to the following rules:
- JsonContent: application/json
- JsonNode or JsonElement
  - If it represents a JSON object or array, application/json
  - Otherwise (e.g. a JSON scalar value), fall back to text/plain
- FormUrlEncodedContent: application/x-www-form-urlencoded
- StringContent: text/plain
- MultipartFormDataContent: multipart/form-data
- MultipartContent (not a FormData subclass): multipart/mixed
- ByteArrayContent, StreamContent, ReadOnlyMemoryContent: application/octet-stream
- byte[], Stream, ReadOnlyMemory<byte>: application/octet-stream
- Other custom HttpContent subclasses (no header set and none of the concrete types above matched): application/octet-stream
- MultipartFile: application/octet-stream
- FileInfo: inferred from the file extension via FileTypeMapper; if it cannot be recognized, defaults to application/octet-stream
- Other complex objects (not a primitive type, enum, or collection): application/json (assumed to be serialized as JSON)
Global default fallback value: If none of the above rules match, the value configured in HttpClientOptions.DefaultContentType is used. This value defaults to text/plain; to change this fallback value, configure it with the following code:

services.AddHttpRemote(builder => {})    .ConfigureOptions(options =>    {        // Set the default request content type (final fallback value)        options.DefaultContentType = "application/json";    });
