+# .NET Client Projects
+
+The .NET client workspace contains the MXAccess Gateway client library, test
+CLI, and unit tests.
+
+## Projects
+
+| Project | Purpose |
+|---------|---------|
+| `MxGateway.Client` | .NET 10 library entry point and raw gRPC client access. |
+| `MxGateway.Client.Cli` | Test CLI for smoke and diagnostic commands. |
+| `MxGateway.Client.Tests` | Unit tests for the scaffold and generated contract wiring. |
+
+The projects reference `src/MxGateway.Contracts/MxGateway.Contracts.csproj` so
+the client compiles against the same generated protobuf and gRPC types as the
+gateway. `clients/dotnet/generated` remains reserved for generator output if a
+future client build switches to client-local `Grpc.Tools` generation.
+
+## Build And Test
+
+```powershell
+dotnet build clients/dotnet/MxGateway.Client.sln
+dotnet test clients/dotnet/MxGateway.Client.sln --no-build
+```
