Switching my ASP.NET Core app to netcoreapp3.0 and adding a global.json for 3.0.100-preview8-013656: all requests hang #13541

kierenj · 2019-08-29T07:38:06Z

Describe the bug

I have a fairly simple ASP.NET Core app. It's been running fine, but I want to get the latest EF Core 3.0 preview, so I can use Cosmos DB. So, I switched to:

<TargetFramework>netcoreapp3.0</TargetFramework>

and added a global.json with:

{ "sdk": { "version": "3.0.100-preview8-013656" } }

(and of course installed the freshest version of 3.0 preview 8)

I'm running from VS 2019 16.2.3.

My app starts, but any requests (to the default endpoint, to swagger, to my file-serving endpoint, or another Web API endpoint) just seem to "hang" open: the browser page pauses, and curl sits there forever. If I break the debugger, there's no managed code running

Note that I did not update any NuGet packages at all, I only made the two changes shared above.

Removing the <PackageReference Include="Microsoft.EntityFrameworkCore.Cosmos" Version="3.0.0-preview8.19405.11" /> dependency (and associated code) and doing back to <TargetFramework>netcoreapp2.1</TargetFramework>, the project immediate starts running correctly as before again.

To Reproduce

It's a tricky one, though it's a simple app, it uses what is currently our own proprietary internal set of nuget packages to "bootstrap" things to get started.

While I can't share the source here at the moment (though I would be happy to, with MS staff, via email), I wonder if there are any pointers that could be shared to help me track this down, diagnose, or collect appropriate info?

Expected behavior

Everything to work as it did before.

Note that I did not update any NuGet packages at all

Please share your current csproj so we can see all of your dependency versions. Note mixing 2.x and 3.0 dependencies is not supported.

kierenj · 2019-08-29T17:02:54Z

Will do. The only 3.0 dependency was the EF Core Cosmos provider package. Would that be enough to mess things up?

Tratcher · 2019-08-29T17:06:45Z

Maybe, that provider has 3.0 dependencies.

kierenj · 2019-08-29T20:05:24Z

Here's my .csproj. I now realise that it may be pretty useless without all of the nuget package sources (they're on a private feed).

It's fine if you were to just say "you can't mix any 3.0 nuget packages we have with any non-3.0 nuget packages we have" - I'll get busy upgrading our universe to 3.0. It was just surprising - no warnings, no build errors, it "runs", just requests hang..

Tratcher · 2019-08-29T20:41:18Z

Yeah, there have been significant breaking changes between 2.2 and 3.0, there's no expectation that any new packages work with the old ones. Upgrade and we'll see how it goes.

kierenj · 2019-08-29T20:54:10Z

I'm trying to do that now - I'm hopeful. I am having some difficulties though I'm sure the resources are out there somewhere, but not forthcoming to me and I'm feeling pretty stupid - so I'd be very grateful indeed if I might bother with you with but one quick question -

How do I upgrade to ASP.NET Core 3.0?

This - https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30 - says "If there's no 3.0 version of a package, the package might have been deprecated in 3.0. ". So that includes my main reference, https://www.nuget.org/packages/Microsoft.AspNetCore.Mvc/ . Indeed, #3756 says I shouldn't use it, instead adding a FrameworkReference to Microsoft.AspNetCore.App.

I worked that out (I figured the docs should probably include that?) - but get:

NETSDK1073
The FrameworkReference 'Microsoft.AspNetCore.App' was not recognized
C:\Program Files\dotnet\sdk\3.0.100-preview8-013656\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets	262

My TargetFramework is netstandard2.1, since this component is a library. Is that where I'm falling short? How can I update my library to 3.0?

Many thanks indeed - with this I hope to be able to get everything up-and-running on 3.0.

Tratcher · 2019-08-29T21:00:39Z

@JunTaoLuo @davidfowl where's our guidance for 3.0 class libraries referencing Microsoft.AspNetCore.App?

JunTaoLuo · 2019-08-29T21:37:15Z

Yes, if your library depends on Microsoft.AspNetCore.App, you'll also need to update your tfm to netcoreapp3.0.

davidfowl · 2019-08-30T01:15:16Z

Yep you need to target the netcoreapp3.0 tfm.

jkotalik · 2019-09-03T21:59:58Z

Shouldn't it also be

<Project Sdk="Microsoft.NET.Sdk.Web">

instead of Microsoft.NET.Sdk?

kierenj · 2019-09-04T06:38:01Z

I dont know - is that a question for me? The migration doc didnt seem to mention it?

JunTaoLuo · 2019-09-06T01:10:04Z

No it doesn't have to use the Web SDK. Though it has a reference to Microsoft.AspNetCore.App, the project itself is a class library and not a runnable app.
