Hey folks, Keep an eye on the Linux repo checklist at the top of this issue. The upload service is really slow today and we're babysitting everything through.

@TaraOverfield in repository dotnet/announcements (issue 151, February 2020 .NET Updates), the link to the Release Notes of .NET Core 3.1.2 doesn't work. It currently links to a file in tag 3.1.1, where it should be 3.1.2.

The correct link is: https://github.com/dotnet/core/blob/master/release-notes/3.1/3.1.2/3.1.2.md

Ok so I am running into this over five times a day, each time it seems to work if I try again in a few minutes. It's turning out to be a major productivity problem when we have multiple image builds per day on cluster - each one has to be manually checked and rerun when they fail. I am just wondering if the RPM repo will ever be reliable:

Downloading packages:
https://packages.microsoft.com/centos/7/prod/netstandard-targeting-pack-2.1.0-x64.rpm: [Errno -1] Package does not match intended download. Suggestion: run yum --enablerepo=packages-microsoft-com-prod clean metadata
Trying other mirror.

Error downloading packages:
  netstandard-targeting-pack-2.1-2.1.0-1.x86_64: [Errno 256] No more mirrors to try.

dagood · 2020-02-20T16:49:11Z

@yoshiya8 check out #4167 for general status on our effort to get the owners of the service to improve its reliability (and updates when we have them).

That said... we haven't heard of flakiness the way you're experiencing it... the typical scenario is a period of downtime (up to 2 hours is "normal" for the RPM repos) but then back up for everyone. I've opened #4298 based on your comment to discuss more since it doesn't sound related to this release.

When migrating from .NET Core 2.2 to 3.1, CORS does not appear to be working properly. I now receive an error saying

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:5000/users/login. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

In the ConfigureServices method, I have:

services.AddCors();

In the Configure method, I have:

app.UseRouting();

app.UseCors(options => options
        .AllowAnyOrigin()
        .AllowAnyHeader()
    );

app.UseAuthentication();

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers();
});

Note: The documentation on Microsoft's website is using outdated code, such as; UseMvc and IHostingEnvironment.

hi,

could you please provide upgrade steps from .net core 2.1 to 2.1.16

pavinan · 2020-03-19T05:01:03Z

Is 3.1.2 is deployed to azure. I don't see it in selection.

kriwec · 2020-03-19T12:18:44Z

Hello,
On .NET Core 3.1 page release date of 3.1.2 is changed from February to 16 March 2020.
https://dotnet.microsoft.com/download/dotnet-core/3.1
This was done by mistake? Or maybe there is new invisible release?
Size of runtimes and hosting packges still the same as in February.

dicksonkimeu · 2020-04-13T22:44:41Z

How can install .NET 3.1.1 on ubuntu and not 3.1.2 ? Becasuse 3.1.2 has breaking changes

svick · 2020-04-14T07:13:11Z

@dicksonkimeu Based on a couple of Stack Exchange answers, you can do the following:

sudo apt update to refresh the list of available versions
apt policy dotnet-runtime-3.1 to see the available package versions.
sudo apt install dotnet-runtime-3.1=3.1.1-1 to install the desired version of the package.
dotnet --info to verify you installed the right thing.

Replace dotnet-runtime with a different dotnet- package depending on what exactly you need.

Also, is the breaking change known? If not, have you reported it?

@michalbilinski See #4360. Ubuntu 20.04 is currently not supported, packages for it should be available on 12 May. In the meantime, you can try the workarounds mentioned in that issue.
