Generate and run C#

Generate and run C#

Use a repository checkout, the Morphir CLI built from it, and SDK 10.0.403. Generation writes source files. Compilation is a separate step and requires the consumer’s compiler and Morphir.SDK.CSharp package.

The fixture exports a daily rate of 5,000 cents. These PowerShell commands create a fresh consumer and a local runtime feed without publishing a package:

dotnet pack src/Morphir.SDK.CSharp/Morphir.SDK.CSharp.csproj --configuration Release --output artifacts/csharp-feed -p:Version=0.0.0-local
dotnet new console --framework net10.0 --output artifacts/csharp-pricing
dotnet add artifacts/csharp-pricing package Morphir.SDK.CSharp --version 0.0.0-local --source "$PWD/artifacts/csharp-feed"
morphir generate --input tests/Fixtures/MorphirIR/daily-rate-v4.json --target csharp --output artifacts/csharp-pricing/Generated --option language-version=14 --option namespace=Pricing.Generated --json

Replace artifacts/csharp-pricing/Program.cs with:

using Pricing.Generated;

var cents = InventoryModule.DailyRate();
if (cents != 5000) throw new System.Exception("Unexpected daily rate");
System.Console.WriteLine(cents);

Then compile and execute:

dotnet build artifacts/csharp-pricing --configuration Release -p:LangVersion=14
dotnet run --project artifacts/csharp-pricing --configuration Release --no-build

The program prints 5000. Generated records and variants use get-only payloads and the SDK’s IMorphirValue equality/hash protocol. Keep the generated files unchanged and use their public API from your consumer code.

Omitting namespace uses the model package, here Car.Rental. Use that namespace in the consumer when generating with default options. language-version=15 requires a separately selected matching .NET 11 compiler for compilation; it does not install or invoke that compiler during generation. Keep toolchain selection separate from the numeric language option.

Input and output must be separate. The output includes .morphir-generated.json. Preserve this manifest so reruns can retain unchanged sources and remove stale owned files while preserving your own files. Semantic failures and cancellation before publication preserve prior output. A filesystem failure during final commit can leave mixed output, as described in the command reference.

See C# troubleshooting for invalid options and located semantic refusals, and the F# walkthrough for the existing F# workflow.
