![]() I had both the connection string with Default Command Timeout=300000 and the CommandTimeout set to 180. OK – I got this working and it's silly what happened. The timeout period elapsed prior to completion of the operation or the server is not responding. 圜ommandExecutionException: An error occurred while executing the command definition. Everything works fine with small datasets. What else can I do to get the EF from timing out? This only happens for very large datasets. I tried setting the CommandTimeout in my repository directly like so: private TrekEntities context = new TrekEntities() This is what my connection string looks like: I added Default Command Timeout=300000 to the connection string in the App.Config file in the project that has the EDMX file as suggested here. I tried the following and have not been able to resolve this issue: > 32Exception: The message or signature supplied for verification has been alteredĪt .RelationalCommand.ExecuteReader(IRelationalConnection connection, IReadOnlyDictionary`2 parameterValues)Īt am getting timeouts using the Entity Framework (EF) when using a function import that takes over 30 seconds to complete. > System.IO.IOException: The decryption operation failed, see inner exception. ![]() > : The Command Timeout expired before the operation completed. : An error occurred while updating the entries. :Error: An exception occurred in the database while saving changes for context type ''. ![]() Module is optimized and the debugger option 'Just My Code' is enabled.
