Aspnetcore: MissingMethodException: Method not found Microsoft.EntityFrameworkCore.Metadata.Builders.IndexBuilder

[ssdeepak]

As per the blog ASP.NET Core updates in .NET Core 3.0 Preview 3
I Installed vs 2019 ,
dotnet new angular -au Individual
after npm install, dotnet restore
and running the app
when I tried to register I got this error

MissingMethodException: Method not found: 'Microsoft.EntityFrameworkCore.Metadata.Builders.IndexBuilder Microsoft.EntityFrameworkCore.Metadata.Builders.EntityTypeBuilder`1.HasIndex(System.Linq.Expressions.Expression`1<System.Func`2<!0,System.Object>>)'.

I have tried this both on Windows and Mac and I get the same error

[Eilon]

@ajcvickers - known breaking change? Any idea on this?

[ajcvickers]

@Eilon No, I don't think this is expected.
@ssdeepak Can you post your csproj file so we can see what is being referenced?

[Eilon]

Tagging @javiercn in case it's something related to Microsoft.AspNetCore.ApiAuthorization.IdentityServer.

[javiercn]

Yes.

This is a known issue. We have it documented in the list of known issues here https://github.com/dotnet/core/blob/master/release-notes/3.0/preview/3.0.0-preview-known-issues.md the 4th bullet point.

This will be fixed in preview 4

[ajcvickers]

@javiercn What's the root cause?

[javiercn]

@ajcvickers It was an incompatibility between the EF versions used by IdentityServer4.EntityFramework.Storage and the versions used by Identity. There was a breaking change in 3.0 where IndexBuilder became generic IndexBuilder and that was causing the method not found exception.

Sadly we didn't discover this for preview3. We have a workaround for preview4 and I'm putting some more tests in the area to ensure that this doesn't go unnoticed moving forward.

[ajcvickers]

@AndriySvyryd Is this a consequence of this break

[AndriySvyryd]

@ajcvickers Yes

[Eilon]

@AndriySvyryd / @ajcvickers - is it a breaking change we would consider reverting, or is it critical for EF Core 3? Just trying to figure out where to balance ecosystem (e.g. major/popular IdentityServer project) vs. best technical decision within EF Core 3.

[ajcvickers]

@Eilon In of itself, yes. However, it won't change the underlying issue here. Regardless of this break or not, mixing EF Core 3.0 in one package and EF Core 2.x in another package is pretty much 100% guaranteed not to work.

[AndriySvyryd]

@Eilon Also this is a binary breaking change only, just recompiling would be enough to fix it.

[Eilon]

Ah OK looks like I don't know the full technical problem. In this scenario, what happens if all EF Core dependencies are lifted to 3.0? Does that work? But in this case some dependencies get lifted by ASP.NET Core references, but others don't, so you end up with a mix of EF Core 3.0 and 2.2?

[ajcvickers]

@Eilon I suppose if everything is lifted to 3.0, then it _might_ work, with NuGet warnings of course.

[javiercn]

@Eilon @ajcvickers Everything gets lifted to 3.0, but when we run through the code path configuring the model it blows up with the method not found exception (as expected)

[brockallen]

@Eilon Also this is a binary breaking change only, just recompiling would be enough to fix it.

This component being used is compiled against 2.2. Any chance of providing the old and new API, so the old code is forward-compat?

[AndriySvyryd]

@brockallen The problem is that the only difference is the return type - it's generic now.

[javiercn]

We are working around this for the time being.

[TanvirArjel]

@javiercn, Why this issue has been closed? Has it been fixed? I am still facing the same problem.

[javiercn]

This is has been fixed and will be available on our next preview release.

@takazm This usually indicates that some packages are coming from one preview, while others are coming from a different preview or a previous release. Make sure that all packages come from the same preview/release.

[VictorioBerra]

This is happening to me too. I think it is also related to a package trying to target EF Core (>= 2.1.0 && < 3.0.0)

[mc0re]

I get the same exception when using InMemory database.

[aTable]

I encountered this issue by having several class libraries with varying versions. As https://github.com/aspnet/AspNetCore/issues/8467#issuecomment-512329385 says, check all your csproj are using a consistent version.

[SteveHindmarsh]

However we can't just make sure all projects reference the same version due to [incompatibilities with SQL Server 2008] (https://github.com/aspnet/EntityFrameworkCore/issues/16400). I have a single project referencing EF Core 2.2.6 whilst all other projects (in same solution) use EF Core 3.0. I can't get around this with the current 'Make sure all projects reference the same version' solution! How else can this be solved? I have a single Blazor Server Side web app project referencing the different EF Core versions in the mentioned data projects. Requesting upgrading the SQL Server 2008 in our corporate environment will take forever!
