Unfortunately, it is hard to suggest anything specific based on the description you provided.
In order for us to provide any help with this, we need to be able to reproduce the problem on our side.
Please provide complete and detailed steps to reproduce the issue as described below:
The steps should begin with launching Visual Studio. They should include every step necessary to create the project from scratch and reproduce the issue.
Please make sure the steps do not involve any 3rd-party code as we will not be able to review it. If the problem only happens with a specific project, please make sure you can reproduce it on a clean project created from scratch. See this page for more information and detailed examples.
The steps should include uncropped screenshots of all wizard pages, VisualGDB Project Properties pages and any other GUI involved in reproducing the problem. This is critical for us to be able to reproduce the problem on our side.
Thanks, we have reproduced the problem and it appears to be a bug in the latest Visual Studio. We have submitted a bug report to Microsoft. Feel free to leave a comment there that the problem affects you as well.
