StackExchange.Redis.StrongName problem in AspNetCore 2.0

[Rodrigo-Andrade]

I am porting an app from the full framework to the new dotnetcore 2.0.

I added StackExchange.Redis as a nuget dependency, when i build the solution i get this:

Error CS0433 The type 'IDatabase' exists in both 'StackExchange.Redis.StrongName, Version=1.2.4.0, Culture=neutral, PublicKeyToken=c219ff1ca8c2ce46' and 'StackExchange.Redis, Version=1.2.6.0, Culture=neutral, PublicKeyToken=null'

my csproj:

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <Folder Include="wwwroot\" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="AWSSDK.S3" Version="3.3.10.1" />
    <PackageReference Include="AWSSDK.SimpleNotificationService" Version="3.3.0.21" />
    <PackageReference Include="Dapper" Version="1.50.2" />
    <PackageReference Include="JetBrains.Annotations" Version="11.0.0" />
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.0" />
    <PackageReference Include="MySqlConnector" Version="0.25.1" />

    <PackageReference Include="Polly" Version="5.3.1" />
    <PackageReference Include="StackExchange.Redis" Version="1.2.6" />
  </ItemGroup>

  <ItemGroup>
    <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.0" />
  </ItemGroup>

</Project>

Ultimately we're included in the Microsoft.AspNetCore.All package, so you can simply remove this line:

<PackageReference Include="StackExchange.Redis" Version="1.2.6" />

i installed the newer version of the strong named package, but, is it intended to only allow strong named versions for dotnet core? it was quite confusing until i got what was going on.

[NickCraver]

@Rodrigo-Andrade There are just 2 packages (one strong, one not). We agree it's confusing since we've gotten so populate (dependency tree-wise). In V2 the main package will be strongly named and .StrongName will go away.

[jkellz-dev]

For others who have run into this issue where .Net Core is still referencing the StrongName package see this issue for the workaround: NuGet/Home#4989

We totally missed an opportunity to ship V2 of SE.Redis, Dapper, etc - with all the breaking changes - on 1st April. Dammit.

When is this going to be resolved? The workaround mentioned does make dotnet build run without errors or warnings - but IDE's, in my case specifically vscode, still shows alot of errors on this...
I'm running with the RC1-final of .NET Core 2.1.

[chris-brown]

If your using netcore 2.1 @elestedt you should be able to move to the new meta-package Microsoft.AspNetCore.App and reference StackExchange.Redis explicitly as it has been taken out of the .all meta-package. More details here: aspnet/Announcements#287

[elestedt]

@chris-brown I am on the Microsoft.AspNetCore.All package - which is the default one. But I'll try swapping to Microsoft.AspNetCore.App and see if it makes a difference.

[erdogangulsoy]

Swapping to Microsoft.AspNetCore.App works! Thanks.

simply install only the nuget-package:
StackExchange.Redis.StrongName

Does anyone has a fix for this? I am trying to upgrade stackexchange.redis in my netcoreapp and keep getting this error.

[uskorc]

@mcheung610 Please see this issue 4989 on nuget home

[dewelloper]

I rembember that edit project file write versions by hand and after it seem to ok

[mesutpiskin]

Does anyone has a fix for this

[akhileshmaithani]

Does anyone have a solution for this I am getting the same error in .NET Core 3.1?

[mgravell]

Without knowing your build dependencies, that's hard to comment on, but: from v2, the StrongName package is effectively redundant and obsolete

Please check the screenshot for build dependencies.

Ah I see - they changed the package name after 2.x, see https://www.nuget.org/packages/Microsoft.Extensions.Caching.StackExchangeRedis/3.1.8 instead of Microsoft.Extensions.Caching.Redis
