 Comment 0: Having the lib from two packages is a very bad idea. Do you need the old
version? Is that coming from another downstream dependency? If so: you
should stick with that version until the other version removes/updates it's
dependencies.

 Comment 1: I had the same issue, The solution is either tweaking your .csproj file or installing one over the other. We really need a permanent fix. It turns out a project depended on another project that depended on the strongname version. took me three days to fix this one.  
 Comment 2: @FrankDupree do you mind sharing your fix for the poor soul who is trying to upgrade `stackexchange.redis` in netcoreapp 2.x?
 Comment 3: <PackageReference Include="Microsoft.Extensions.Caching.Redis" Version="2.2.0" />
改为
<PackageReference Include="Microsoft.Extensions.Caching.StackExchangeRedis" Version="3.1.0" />
 Comment 4: 用新装  Include="Microsoft.Extensions.Caching.StackExchangeRedis" Version="3.1.0"
