But this changes the timeout for all the queries that are made using the same DbContext instance. Note: EF Core will only execute the query with less than 100 seconds time. This will only work with 2.1.0 or above, you will get exception if you try this with . But () 180.So, am I not creating the command object properly I would imagine the preferred method is something like: (query) or (query), but the problem is that the query results cannot be mapped to MyEntity and I need the results of the query not just the of.
