When using Hangfire library into .net core application, There is a version conflict occured between two different Dapper library. One version is V1.5.0 from Nuget package, and another version is V1.0.0 reference from my local .net core project. There is an error when running program.
System.IO.FileLoadException HResult=0x80131040 Message=Could not load file or assembly 'Dapper, Version=18.104.22.168, Culture=neutral, PublicKeyToken=null'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) Source=Hangfire.SqlServer StackTrace: at Hangfire.SqlServer.SqlServerObjectsInstaller.Install(DbConnection connection, String schema) at Hangfire.SqlServer.SqlServerStorage.<>c__DisplayClass24_0.<UseConnection>b__0(DbConnection connection) at Hangfire.SqlServer.SqlServerStorage.UseConnection[T](DbConnection dedicatedConnection, Func`2 func) at Hangfire.SqlServer.SqlServerStorage.UseConnection(DbConnection dedicatedConnection, Action`1 action) at Hangfire.SqlServer.SqlServerStorage.Initialize() at Hangfire.SqlServerStorageExtensions.UseSqlServerStorage(IGlobalConfiguration configuration, String nameOrConnectionString)
Unfortunately, I have to keep the old version library rather to replcace it. How can I resolve the package version conflict meanwhile two library exist together. Hope someone can find a nice solution. Thanks!
Uninstall Dapper in Nuget and install the version that it is looking for, in my case 22.214.171.124. Not sure why Hangfire is coded to a specific version, but this solves the issue.
Hopefully this is a not a permanent bug on their end, but this will work until it is fixed.
