As I commented to the blog, checksum text is not available.

Also, Microsoft has closed the previous issue without any reply to my comment.

I'd like to know your plan.

[vivmishra]

Thanks for reporting the issues:

• ASP.NET Core release notes link is now working.
• The checksums are available from https://www.microsoft.com/net/download/dotnet-core/2.2

@tanaka-takayoshi, for 2.2 Previews feed-based package manager support is not available. You can use the tarballs for installing the product.

@leecow

[tanaka-takayoshi]

@vivmishra Thanks!
I confirmed checksums are available. Also, thank you for sharing the plan.

[Alexandre-Nourissier]

Great news !
Mind that the release notes links are broken in this file :/release-notes/2.2/README.md@master.

The links are redirecting to ./preview/2.2-preview*.md instead of ./preview/2.2.0-preview*.md .

[vivmishra]

Thanks. The 2.2 README.md is fixed to point to the right location.

[leecow]

@tanaka-takayoshi - We did publish 2.1 preview releases to the package manager feeds but mixing production stable and previews on the same feed caused quite a bit of grief for some folks. Because of that, we decided to not publish preview installers to this feed any longer. There may come a time where we have a preview-only feed but no plans on the calendar yet.

What are the instructions for removing preview 1 and other sdk's/runtimes?

Do you folks know how to get the preview in travis ci for ci testing?

[leecow]

@steveoh - You can use the add/remove programs control panel on Windows. All other OS's will be a manual process. If you can share your output from dotnet --info, I can be more specific.

[steveoh]

@leecow sure!

[leecow]

Thanks Steve. Mac removals are all manual at this point. Details are available in this article. We do want to make managing installed versions a better experience and can hopefully make progress in 3.0.

[steveoh]

Thanks @leecow. I was able to uninstall most things except the runtimes did not shrink as much as I was hoping...

Microsoft.AspNetCore.All 2.1.0 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.1.1 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.1.2 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.1.3 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.2.0-preview1-35029 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.2.0-preview2-35157 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.2.0-preview2-35157 [/usr/local/share/dotnet/shared/Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.2.0-preview2-26905-02 [/usr/local/share/dotnet/shared/Microsoft.NETCore.App]

Should there be instructions to delete the Microsoft.AspNetCore.All items?

[leecow]

The instructions will be the same, just substitute in the directory you're looking to clean up. For example, the following (using your list as the starting point) will leave only AspNetCore.All/2.1.3 installed.

cd /usr/local/share/dotnet/shared/Microsoft.AspNetCore.All
sudo rm -rf 2.1.0 2.1.1 2.1.2

[rquackenbush]

How do I determine if dotnet/coreclr#19606 is included in this preview?

[karelz]

@rquackenbush the easiest thing is to inspect the code: https://github.com/dotnet/coreclr/tree/v2.2.0-preview2
It's not there: https://github.com/dotnet/coreclr/blob/v2.2.0-preview2/src/pal/src/synchobj/mutex.cpp#L805-L808
It does not seem to be ported to release/2.2 branch yet: https://github.com/dotnet/coreclr/blob/release/2.2/src/pal/src/synchobj/mutex.cpp#L805-L808

[karelz]

Replaced by Preview3 - see #2004
