BuildWebHost is unavailable

[gjaryczewski]

With SDK 2.1, it looks like BuildWebHost(args) should be replaced by CreateWebHostBuilder(args).Build().

Hello @gjaryczewski ... We're still in progress on getting these references updated on #6091 and #5495. We'll get to this asap.

@Rick-Anderson, this one didn't make the cut for work on #6562. I was initially under the impression we hadn't worked the RP tutorial yet. I better leave this open until you have a chance to take a look. If you want me to catch it in my final sweep of topics later on #6091, let's close this, and I'll work it on #6091.

The above code in program.cs leads to the error:
InvalidProgramException: Vararg calling convention not supported.

When will this part of the tutorial will be updated to .NET CORE 2.1? I'm stuck at this part and i can't get progress. I've changed

CreateWebHostBuilder(args).Build().Run();

to

var host = CreateWebHostBuilder(args).Build();
host.Run();

but even then there is no chance to make

var scope = host.Services.CreateScope();

because the method doesn't exist. Instead there is a method called GetService(), but at that point i don't get any clue how to step further. Debugging don't show any variables, even my breakpoint is simply ignored (or perhaps never reached, i really don't know)

Even if you don't update the tutorial, can you please describe in the comments, how to implement the SeedData-class in the startup-process?`

Thx.

Humpf....

Now there is CreateScope(). I don't know what i've done wrong.

Sorry...

Just a last comment:

using Microsoft.Extensions.DepencyInjection;

That was my missing part. Sorry @ALL... I'll promise to read more carefully in the future...

Just in passing, the seeding approach is a change in progress. For an example, see this remark ... #9205 (comment)

The issues where the work is occurring can be found by searching the repo issues: https://github.com/aspnet/Docs/issues?q=is%3Aissue+seed+is%3Aopen

I think some of the closed issues may indicate where some of the topics use the new approach. All of the topic samples will eventually use the new approach. I think the remaining topics will get attention after 2.2 comes out, and that's tentatively scheduled to happen by year's end.
