Class UserAgent
- Namespace
- DatabentoDotNet
- Assembly
- DatabentoDotNet.Dbn.dll
The identity string this client sends on every request: the live gateway's client=
field on authentication, and the historical client's HTTP User-Agent header. One
string, because both are the same identity — there is deliberately no second, HTTP-specific
variant.

Remarks
Port of upstream's USER_AGENT (lib.rs:288-295), which formats
Databento/{crate version} Rust {os}-{arch}. **The leading token is deliberately
DatabentoDotNet, not Databento**: this is a third-party client, and a user agent
that says otherwise would misattribute this library's traffic — and its bugs — to the vendor's
own clients in their logs. Same reason the package is not Databento.*; see CLAUDE.md,
"Naming".
The platform token is .NET's runtime identifier — osx-arm64, linux-x64,
win-x64 — which carries the OS and the architecture that upstream reports separately.
This type moved here from DatabentoDotNet.Live in #32. DatabentoDotNet.UserAgent.Build() reads
its own version off typeof(UserAgent).Assembly, which now resolves to the codec
assembly rather than the live one. That is not a behavior change: every project shares
VersionPrefix from Directory.Build.props, so the rendered version is identical
either way — it would only start to matter if a project were ever versioned independently of
the others.
