You should place some code so we can see what is causing the error.

About the only thing anyone can tell you from what you've posted is that the SQL Server took too long to finish executing your query, what that is. Nobody can tell you anything more than that because you have shown the query and code that's throwing the error.

Maybe you're "piling up too much work" (in memory) before "saving changes".

EF is no replacement for "responsible computing".

you could try increasing your timeout, but seems to me the sql code should be faster so I would focus on making sure its efficient.

Not a question at all!

the error is related to system timeout.you can see it on the error message as

System.ComponentModel.Win32Exception: The wait operation timed out

it simply mean that sql take too long to execute your query and the timeout occur.There might be many reasons causing a command executed for a long time like Long running tasks, Server memory pressure, Blocking, Other resource bottlenecks etc:-. Only detail look at the codes and data can provide the exact reason for the timeout.

this link provide some basics on the issue..
