Hangfire: Cannot use Hangfire 1.6.22 with Dapper version >= 1.50.1

[ensecoz]

Steps:

1. Open aspnet core 2.2 project
2. Install Dapper v1.50.7 (latest) via nuget
3. Install Hangfire v1.6.22 (latest) via nuget
4. Run and you will get this error:
   FileLoadException: Could not load file or assembly 'Dapper, Version=1.50.1.0, Culture=neutral, PublicKeyToken=null'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Hm, but it works with Dapper 1.50.5 and below just fine. I could recommend you to try using Hangfire 1.7.0-beta4 as Dapper package is internalized there or downgrade Dapper.

I was also having an issue using Hangfire with Dapper 1.50.7, but I noticed that there is now an update for Dapper to version 1.60.1, which works fine with Hangfire 1.6.22.

<PackageReference Include="Dapper" Version="1.60.1" />
<PackageReference Include="Hangfire.AspNetCore" Version="1.6.22" />
<PackageReference Include="Hangfire.SqlServer" Version="1.6.22" />

@mustex Confirmed, updating to the latest version of Dapper helped me as well
