Microsoft.AspNetCore.DataProtection.Abstractions higher version than referenced assembly

[pjmagee]

Describe the bug

Cannot write tests for IDataProtectionProvider because Visual Studio thinks I'm referencing a higher version in my main library. (The versions only go up to 2.2.0)

To Reproduce

Steps to reproduce the behavior:

1. Using this version of ASP.NET Core '3.0.100-preview3-010431'
2. Run this code 'Any class that injects IDataProtectionProvider'
3. Create xunit testing library and try to Mock / Stub IDataProtectionProvider
4. Both app and nunit project using netcoreapp3.0
5. See compiler errors regarding version of Abstractions.

Expected behavior

That the compiler errors should just use the version the main library is using.

Additional context

The .NET Core website runs perfectly fine. Including the DataProtector library, I've checked my database and it's encrypting the data. However, I have to comment out any class that uses this because the test project wont compile.

Include the output of dotnet --info

Mixing package versions of Microsoft.AspNetCore.* is not supported. Looks like the "Main Project" is referencing DataProtection 2.2. That will need to be updated to 3.0 as well.

Hi @Eilon , I could not find a 3.0 version, do i need to add a feed for this or is this something that will come at a later stage?

Thanks

[Eilon]

Ah, you are right. That is one of the package that was moved into the ASP.NET "Shared framework." You can read more about that in the ASP.NET Core migration guide from 2.2 to 3.0: https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-2.2&tabs=visual-studio

And there is some additional reference information here:

• Breaking changes to Microsoft.AspNetCore.App in 3.0 aspnet/Announcements#325
• Replace PackageReference to Microsoft.AspNetCore.App with FrameworkReference #3612
• Stop producing packages for shared framework assemblies in 3.0 #3756

Thanks! I'll take a look at this in a few hours. Appreciate the help.

Fixed it with your help, now i reference <PackageReference Include="Microsoft.AspNetCore.App" Version="3.0.0-preview3-19153-02" /> in my unit tests and removed the <PackageReference Include="Microsoft.AspNetCore.DataProtection" Version="2.2.0" /> from the 'Main project', since its already in the shared framework.

Closing this as now it compiles and i can run the tests.

Awesome!
