Describe the bug

Migration from 2.2 to 3.1.
Project Sdk as Microsoft.NET.Sdk.
Reference <FrameworkReference Include="Microsoft.AspNetCore.App"/> searches for aspnet 2.0.0 when building:

SoftinuxBase.Security.Common -> F:\Developpement\Base\src\SoftinuxBase.Security.Common\bin\Debug\netcoreapp3.1\SoftinuxBase.Security.Common.dll
  It was not possible to find any compatible framework version

Can you provide all of the code for the project? Seems like this is a class library (which isn't runnable)

davidfowl picture davidfowl on 9 Feb 2020

@davidfowl yes, you can see here https://github.com/SOFTINUX/Base/tree/NewPermissionsSystem
It's like a partial app but I use Extcore to make that.

See the migration guide for https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-3.1&tabs=visual-studio.

You shouldn't have these packages on .NET Core 3.1 applications/libraries.

davidfowl picture davidfowl on 9 Feb 2020

@davidfowl I have already followed this page.
I didn't commit my last work because it's not stable.

I have been busy migrating the project for 3 days.

The non-committed csproj file is the one I put in the issue.

If I declare the application as Microsoft.NET.Sdk.Web, the application does not build because it claims for a Main entry point for this project.

It is for this reason that I set <FrameworkReference Include = "Microsoft.AspNetCore.App" />

I keep the application as a classlib and it has references to mvc because of IAuthorizationFilter

Hi,
I continue my investigations.

I discover that Visual Studio 2019 add's Microsoft.AspNetCore.App 2.1.15 after repairing.
So, you can never have this error when VS2019 is installed.

But, on Linux, you cannot have VS2019 and you have this error.
I suppose it's same on Mac.

@Xarkam Were you able to solve the problem? I have the same issue. It works good in VS2019 but fails in my codepipeline running on linux machine.

When you install .NET Core SDK 3.1, it installs only the .NET Core SDK 3.1 and the runtime for 3.1 version. You doesn't get the 2.1.x runtime version. You must install it additionnaly to the .NET Core SDK 3.1.

And it's the same problem with mcr.microsoft.com/dotnet/core/sdk Docker image... it seems to contain only 3.1 runtime.

It's a bit odd because I don't think that case is properly documented somewhere...

tremblaysimon picture tremblaysimon on 14 May 2020

What I understand is for some 2.x project (like ones using Razor), we must keep a runtime version of 2.1 on the system that builds the project.

Why is that odd?

davidfowl picture davidfowl on 14 May 2020

@davidfowl, maybe the word odd is not the right one.

What I wanted to say is more about the fact that when we have a webapi created with 2.1 sdk for example we can easily buid it using an image that contains only the .NET Core 3.1 sdk.

But if you have some razor pages created using 2.1 sdk you will not be able to achieve a build with .NET Core 3.1 sdk. You must get the runtime for 2.1 too to achieve that.

In the end, I think it's more something I didn't understand (or found in an official doc) about backward-compatibility or not of .NET Core 3.1 sdk with the previous ones.

Tagging @NTaylorMullen on this stale issue. I think the issue is that tools like rzc which used to be in packages didn't have automatic roll-forward to the next major runtime.

I'm pretty sure we addressed this in .NET 5.

I'm pretty sure we addressed this in .NET 5.

We've done a lot in the .NET 5 time frame and although I personally didn't do the work to enable it I wouldn't be surprised if it was fixed either.

@tremblaysimon would you mind trying to install the .NET 5 preview SDK to see if the issue persists? If it does that definitely wouldn't be ideal 馃槃

@NTaylorMullen, sorry I didn't give me time to try it now. I will try this today to see if it persists and give you feedback.

It's a real problem to have multiple versions of the sdk.
This implies that when you carry out an asp project in 2.1 that then you change the runtime to 3.1 in the csproj, somewhere, there is a strong relationship on the sdk / runtime 2.1

In the migration documentation 2.1 -> 3.1, nothing is indicated on this subject.

I can no longer confirm, but it seems to me that I had tested a template project in 2.1 directly passed to 3.1 without other modifications than those indicated in the documentation of migration from 2.1 to 3.1 and that the problem was present.

In release mode, do you have a full 3.1 package or a 2.1 / 3.1 mix?

@NTaylorMullen is it possible to reopen that issue?
