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 can't comment as I'm just under the minimum comment reputation, however I have been having exactly the same issue.

Like you, I re-installed Windows 10 (Enterprise) and Visual Studio (both 2013 Pro and 2015 Pro) to no avail.

For the moment, I've put this on the back-burner and am working around it by using a combination of DevArt's Entity Developer (https://www.devart.com/entitydeveloper/) and manually editing the classes to match database changes.

It is tedious, and not a lot of fun - but it works for me (for the moment).

Hopefully this helps someone.

Edit:

For anyone who may come across this post in the future, the following appears to have solved this issue for me:

• Navigate to Tools > Options > General
• Untick "Automatically adjust visual experience based on client performance"
• Untick "Use graphics acceleration if available"

Though you may not have to, I left "Enable rich client visual experience" unticked.

If this doesn't work, take a look at the comments below this answer - it might be of use. :)

Edit 2:

My issue came back, and after further investigation it appears that it was caused by Remote Desktop (I am currently using an ESXi-hosted Windows 10 VM). Switching to VNC or using the VMWare VSphere Web Console results in Visual Studio running perfectly fine. Hopefully this helps someone! :)
