VS2015 - CPU usage flatlined, unable to detach debugger or close IDE

[israeld]

We have a solution working flawlessly in VS2013, using dotConnect for Oracle (8.5) running against 64bit Oracle Client (11.2.0).

When opening the solution to VS2015 the CPU usage hits the roof and flatlines. We are able to start debugging but unable to stop debugging (debugger won't detach), also when trying to close the IDE the devenv.exe process stays behind with CPU usage flatlined.

This is the exact same behaviour that this person is reporting (although they do not appear to be using dotConnect): https://social.msdn.microsoft.com/Forum ... diogeneral

I should point out that if I comment out all of our connection strings from our web.config files these problems do not occur. Likewise if I switch our connection strings over to direct=true the problems do not occur.

Any help would be greatly appreciated?

We could not reproduce the issue. Please create and send us a small test project which reproduces the issue. Please also describe the steps we should perform for reproducing the issue.

Here is a very simple example, just an empty web project containing a web.config with sanitised versions of our connection strings. Using this example we have replicated the issue on 3 different developers machines.

Here are the steps to replicate the issue:

• Open the solution
• CPU usage should now climb up for the devenv process and not return to zero
• Close Visual Studio
• The devenv process should now to stuck, chewing up CPU, unable to close until the process is killed manually.

FYI we are running:

• Windows 8.1
• VS2015
• x64 Oracle Client 11.2.0.1.0
• dotConnect 8.5

Hello,
I encountered the same error using VS2015 and dotConnect 8.5,
but direct connection dont solve it.

[israeld]

Yes you're right, direct didn't solve the problem for us either. I thought it did when I made my first post but that was a mistake.

Hopefully the devart folks can come through with a fix for us, this is the only thing stopping my team from moving to VS2015.

Unfortunately, there is an invalid project by this link. We have created an empty Web Application and added your web.config to it, but we can't reproduce the issue.

Please send us the complete test project, which reproduces the issue. You can send us this project using the following form. At the bottom of this form you can attach a file up to 2 MB.

Please also tell us the edition of your Visual Studio.

I have submitted a new example solution through the contact form.

[Pinturiccio]

We have reproduced the issue. We will investigate it and post here about the results as soon as possible.

Hi Pinturiccio,
Has there been any progress on this issue?

[Pinturiccio]

We are investigating the issue and will post here when we get any results.

When studying the issue, we have found that it is reproduced not only with dotConnect for Oracle, but with other providers too, even with providers to databases other than Oracle.

Visual Studio 2015 has a new feature of adding connection strings from the web.config file to Server Explorer automatically. It seems that it has a bug causing Visual Studio to stop responding when there are 5 or more connections in the web.config file.

Since this is a Visual Studio bug, we cannot do anything with it. We recommend you to contact Microsoft support.

I'm sorry but that's not a good enough response.

As stated on your About Us page, Devart is a Microsoft Silver Application Development Partner, as a partner organisation you should be able to contact Microsoft directly. Furthermore I think that you owe it to your paying customers to do so.

You also advertise that the product has VS2015 support https://www.devart.com/dotconnect/oracl ... patibility and right now you are not providing that compatibility. How can you claim VS2015 support when it doesn't actually work?

My organisation has been a loyal Devart customer for several years and have been extremely happy up until now. Right now we are stuck, unable to upgrade to VS2015 and it is not fair for you to push it back on me and tell me to contact MS.

We have submitted a ticket to Microsoft support: https://connect.microsoft.com/VisualStu ... s/1987980/

We will post here when Microsoft's support team replies to it.
