gRPC + ASP.NET Core as a Migration Path for WCFs in .NET Core
| Feature | WCF | ASP.Net Core + gRPC |
| Platforms | Windows | Windows, Linux, MacOS |
| Protocols | LRPC/Named Pipes/HTTP/TCP/MSMQ | Binary (GRPC) + HTTP2 (TCP/Named Pipes/LRPC) .AddProtocol(“ncacn_ip_tcp”, “8080”) .AddProtocol(“ncacn_np”, @”\pipe\MyService”) .AddProtocol(“ncalrpc”, “MyService”) By removing the ASP.NET Core stack and just using .NET Core |
| Injected Aspects | Behaviors | ASP.NET Core DI Middleware/ gRPC interceptors |
| Distributed Transactions | *Yes – [TransactionFlow], transactionscopes, and supported bindings | *No |

IEnumerable<T> is a good fit for many scenarios, but do consider that IReadOnlyCollection<T>
might be a better fit in circumstances where the collection is always
going to be fully available in memory. Avoid passing round mutable
collection types as this can cause confusion about who owns the
collection.
By placing under source control everything we need to describe any version of a database, we make it much easier to achieve consistent database builds and releases, to find out who made which changes and why, and to access all database support materials. Matthew Skelton explains how to make sure your version control system fully supports all phases of the database lifecycle, from governance, development, delivery and through to operations.
