> {{Server \-tr:http}} in the netstd tutorial stops at startup, so none of the
> HTTP samples can be run:
> {noformat}
> crit: Microsoft.AspNetCore.Hosting.Diagnostics[6]
> Application startup exception
> System.InvalidOperationException: Multiple constructors accepting all
> given argument types have been found in type
> 'Thrift.Transport.Server.THttpServerTransport'. There should only be one
> applicable constructor.

> The tutorial adds the middleware with
> {{app.UseMiddleware<THttpServerTransport>()}}
> ([Server/Program.cs:366|https://github.com/apache/thrift/blob/bcdf956895aeac5411ce3029ab8b33901b7c7a36/tutorial/netstd/Server/Program.cs#L366]).
> The only argument the activator gets is the {{RequestDelegate}}, and all
> three public {{THttpServerTransport}} constructors accept one, so it cannot
> choose.
> Passing the processor and a configuration explicitly fixes it:
> {code:java}
> app.UseMiddleware<THttpServerTransport>(app.ApplicationServices.GetRequiredService<ITAsyncProcessor>(),
> new TConfiguration());
> {code}
> With that line the server starts, and {{Client \-tr:http}} completes all its
> calls.
> Checked on master (bcdf956) with the .NET 10.0.401 SDK. The tutorial server
> and {{THttpServerTransport}} are the same on master, release/0.25.0 and
> release/0.24.0. No CI job builds or runs {{tutorial/netstd}}.
