This item was ported from a public Connect issue - https://connect.microsoft.com/VisualStudio/feedback/details/757222/entity-framework-randomly-reorders-imported-function-parameters-for-stored-proc
Problem Description:
Example: I have a stored procedure (let's call it sp_X) that receives an int and a string parameter. I add it to my entity framework model and import it as a function. The function import correctly builds a method that receives an int as the first parameter, a string as the second. This will work for months -- even after adding additional new (unrelated) function imports to the model and rebuilding multiple times -- and then, randomly after adding some new object to the model and updating model from database, I'll get a compile error because the function for sp_X's int and string parameters have been flipped .... it's now sp_X(string, int). No changes have been made to the proc (sp_X). I have to remove the proc and function from the model and reload both in order to correct the problem -- but this flipping behavior will return randomly for this proc. I read recently that if I drop/recreate the proc the problem will be corrected long-term but this is not an ideal solution since, in the case of a stored procedure with string, string parameters, I won't get a compile error when they flip but I will get run-time issues because the function is now sending string 1 to the string 2 parameter and string 2 to the string 1 parameter. Note: I am currently using the Entity Framework 4.0.30319.
