Solution ( user created sql function or tabled valued function is not visible in the edmx)

I faced a problem with the table valued function or user created function when i was trying to add it to the edmx. The problem that i was having a function in the sqlserver but when i tried to update the edmx to add the same function into it.
 The function name was not visible.I searched a lot over the net about this but could not able to find the solution but finally. I got it how to do it.

 











As the above image shows that i was targeting the .net framework 4 just change it to 4.5 and it worked for me 

 











 And now in the below image you can see that i was able to see the function name which i wanted to add to the edmx
