Targeting .NET 10.0 or higher in Visual Studio 2022 17.14 is not supported

[panxn]

I'm using VS17.14. After updating .NET10 SDK, I see a warning:

C:\Program Files\dotnet\sdk\10.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.DefaultItems.targets(145,5): warning NETSDK1233: Targeting .NET 10.0 or higher in Visual Studio 2022 17.14 is not supported.

This page states .NET10 is compatible with VS17.14.

And the file sdk\10.0.100\minimumMSBuildVersion is also 17.14.0

I want to ask:

1. Why do you add this warning? Does it make sense? Can you remove this warning?
2. Is it safe to use .NET10+VS17.14? It works now, but will you break it later?

Thanks!

That page states that it is supported to use .NET 10 for targeting net9.0 and lower. Is is not supported to target .net10.0 using .NET SDK 10 in VS 2022, for that you must use VS 2026.

This is aligned with the same behaviors from previous years - if you look at that table on the page you linked you can see ever .NET SDK .100 version supports building the earlier Target Frameworks on previous VS versions, but you must always update your VS to target the new Target Frameworks.

@baronfel so this reply is wrong? #51266 (comment)

I feel confused about the term "Minimum Visual Studio version".

It sounds like ".NET10 SDK can work in VS17.14" doesn't mean ".NET10 TargetFramework can work in VS17.14"

This is exactly correct (and is the same as every previous .NET release). We have only ever supporting targeting the older TFMs using the new SDK in the old VS. Using the new TFM has always required updating VS.
