Ledger clients quickstart Resolve ICantonLedgerClient (from Canton.Ledger.Abstractions) from the container; the transport package you reference decides whether it speaks gRPC or the JSON Ledger API. Register a client dotnet add package Canton.Ledger.Grpc.Client service

Canton .NET SDK Build .NET applications on a Canton/Daml ledger with full type safety. dpm codegen-cs turns a Daml .dar archive into strongly-typed C#, and one transport-neutral ICantonLedgerClient submits it over gRPC or the JSON Ledger API, with a PQS client, authentication, OpenTelemetry

Status, platform support and roadmap Where the SDK stands: release status, the OS and architecture CI covers, test coverage and what is planned next. Back to the README. Status Active. Curated public releases land here; ongoing development happens in a private development rep

Daml to C# type mappings How every Daml type maps to a C# type and a Daml.Runtime type, including the Optional, Numeric and Party edge cases. Back to the README. | Daml Type | C# Type | Runtime Type | |-----------|---------|--------------| | Int | long | DamlInt64

Canton .NET SDK Lets .NET applications talk to a Canton participant with full Daml type safety. The codegen generates strongly-typed C# from Daml .dar archives: a JVM-side helper wraps daml-lf-archive to decode a DAR into an intermediate representation, and a .NET-side emitter consumes that re

JVM codegen helper Scala/JVM binary that wraps daml-lf-archive to decode a .dar archive and emit an IntermediateDar protobuf message to disk. See JVM helper and AstToIntermediate translat

🚀 Canton .NET SDK: 0.7.1 TL;DR: a hardening release on the 0.7 line ✅: Daml.Codegen.CSharp.MSBuild is now published, so bindings generate at dotnet build time with no JDK needed ✅, and telemetry hides party, user and contract ids unless you opt in ✅. It also removes some API surface, so

🚀 Canton .NET SDK: 0.8.0 TL;DR: Canton 3.7: the clients target Canton 3.7.1 and support Canton 3.7 only. External-party onboarding accepts protocol version 37's v31 topology transactions. Canton 3.6 users stay on 0.7.x. 0.8.0 is a breaking release that opens the Canton 3.7 line on Canton 3
