Can I use the upgrade assistant to upgrade to .NET Core 3.1?

Hi,

Question is simply as the title states! Can I use this to migrate to .NET Core 3.1?

Thanks

Yes, if you use the --target-tfm-support LTS parameter, Upgrade Assistant will upgrade apps to .NET Core 3.1 (libraries will still upgrade to .NET Standard 2.0, if possible).

Upgrade Assistant supports upgrading to LTS (3.1), Current (5.0), or Preview (6.0) releases of .NET.

I'm having the same problem. The team where I work is unable to use net6 due to impediments on the part of the infrastructure team and unfortunately the only option we have is to use net5, until the problem that the other team generates can be solved.

@squirrl The idea is to support upgrading to the latest .NET version that is current or LTS or in Preview, hence the change to have it all point to .NET 6. We will be working on making Preview point to .NET 7 soon. /cc @brandonh-msft @cathysull

@drielnox .NET 5 is EOL as of May 2022 so the recommendation is to move to a version that has long-term support - .NET 6.

@squirrl - You can always check to see which .NET versions are currently supported and when they are scheduled to move out of support here: https://dotnet.microsoft.com/en-us/platform/support/policy

Thanks for the replies. It's just strange to me that this tool no longer supports 3.1, which is still LTS, since to my knowledge VS2019 doesn't support 6.0.

Were it up to me, this tool would allow users to specify exactly which version of .Net to use, since 3.1 is technically still LTS, and there are surely legitimate business needs to use it rather than the newer LTS.

For me, it doesn't matter, I found a different solution. Thanks again.

@squirrl is it acceptable for you to use an older version of the tool, perhaps?
