Entity Framework edmx click on diagram very slow

Question

Background first: I have a database-first EF6 model in Visual Studio 2015 (latest nuget 6.1.3 pointing to a local SQL Server 2014 SP1 Express database) on a Windows 10 Pro lapto

Answer 1

I tried the accepted answer and it did work for me, however the issue returned on restart. I also tried the other answers with no success. I found the offending windows service and used Windows 10 services management screen to disable the service. I hope this is helpful to others with this issue.

How to disable the service fully

Disable the service:

1. User windows start search (by the start menu) and type in: Services
2. You should see a windows desktop app called Services (open it).
3. Find the services called "Touch Keyboard and Handwriting Panel Service".
4. Open its properties, (by right clicking it).
5. Under the General tab set the startup type to "Disabled".
6. Stop the service if if it has not stooped already.

Verification:

7. Open Visual Studio's EDMX and you should notice the difference right-away, if not then you may not have the same issue as me.
8. Restart your computer and test the EDMX again, it should not be slow.

Note: This does mess with your gesture and touch pad a bit, so if you use that a lot then don't do this. This guide is for windows 10, and worked for me but may not work for you. Also I have not tested if Windows update will re-enable the service.
