While testing application compatibility on Windows 10, one of my customers encountered an issue creating a new project in Visual Studio 2015 when FIPS was enabled. A new project could be completed successfully one time, but all future attempts to create a new project failed with an error message stating “Object reference not set to an instance of an object”.
We isolated the issue to the FIPS security hardening requirement included as part of the Windows 10 Security Technical Implementation Guideline. For additional details, see the following link:

With this information, we then worked with the Visual Studio product group to collect trace/stack information, and the developer was able to isolate the problem to a known issue in the “Application Insights for Visual Studio” extension. The bug has already been fixed, which allowed us to perform the following steps to resolve the issue on our development machine:
Without elevated privileges, the disable button is grayed out and the uninstall does not successfully uninstall the extension.
Running in elevated mode allows you to uninstall the extension. Restart Visual Studio to see the change and you are able to create new projects again successfully.
Special thanks to the amazing Joie Andrew, John Gardner, and Bertan Aygun for the great assistance on identifying, analyzing, and testing the scenario and solution.
Thanks,
Sam Lester (MSFT)
Additional note: If you are working in an environment that requires FIPS to be enabled, we also identified a FIPS related bug in Power BI Desktop that has now been fixed.
