See this StackOverflow question for some background. Hangfire looks like the right solution for me but I\'m having trouble getting it to work. My development environment is VB
My development environment is VB 2010 with SQL 2005.
Cannot find data type datetime2
This is probably where your issue lies.
Had a quick look at the schema of Hangfire tables and can see that HangFire.Hash table uses datetime2 type for the ExpireAt column.
According to this thread, Sql Server 2005 doesn't support this type, as it has only been introduced in Sql Server 2008.
