I work on around 35/40 different projects, I have one project which when I open it from source control explorer displays blank entries when viewing it in solution explorer. If I click on any of these blank entries in solution explorer visual studio 2015 crashes. This has been happening with both update 1 and update 2 of VS 2015. Can't remember if it happened on vanilla 2015 and I don't have 2013 installed to try with that.

 

I'm able to access all the files in the solution and open them to edit if I browse to then via source control explorer.

 

I've tried disabling all my extensions, I've tried running studio in safe mode. Still happens. I've also tried nuking my profile by running devenv.exe /ResetUserData but it still happens when I open this one particular project.

 

Has anyone came across this before or know how to fix it?

 

The only thing I've found that fixes it is to delete the .vs folder in the project and re-open the solution. This fixes it for a while but then I can open the solution again and there are blank entries again.

Things to try:

 

1. Run VS2015 in admin mode to see if it is a permission issue.

 

2. Check for odd char encodings or special chars in the files.

 

3. manually edit the csproj file and the project.json and look for anonmolies. Or delete all the project files and re-create the projects into a new solution if that is feasible.

It might help people if you reference your previous question on the same topic:

 

 

 

I'd actually forgotten I'd posted it here previously. I thought I'd only posted on Stackoverflow. :blush:

"Usually this is caused by extra references in either the .sln or .suo files."

Thanks, I'm not sure what I did differently but I deleted all the files locally and got the latest code from source control and the problem seems to have fixed itself.

 

 

- It seems that every time you start over, you are just pulling the problem in again from your source control. You should examine your sln/csproj/projectjson files in extreme detail to see if something is odd with them.

 

- Also consider setting everything on your computer and VS to U.S. English to eliminate character encodings as a potential issue.

 

- Anything out of ordinary with the computer hardware such as non-standard keyboard, other input devices, running in a VM, etc

1. Running in admin doesn't help, still get blank entries.

2. I haven't checked all the file (there are thousands) but the ones I have checked all seem fine.

3. That's not something that's possible unfortunately.

Although it is only the one project, it seems like the type of error condition that VS2015 should be able to handle without crashing.

 

- so you probably have Update 3 installed but if not...

 

- you have given no details on your specific hardware and software and the type of project - ASP.NET or Console or WPF or UWP etc.

 

- for me I have observed that VS2015 is very glitchy on older hardware specially computers that can't run Hyper-V. This is a voodoo type tip which I really hate but turn on Hyper-V just in case it helps (needs a reboot) . Solved some really weird VS2015 bugs for me.

 

- try Microsoft Connect site and enter the problem description. They will respond, sometimes with useful info.

- any VS add-ons could be a suspect - perhaps disable them for a test

 

- any software that monitors keystrokes could connect to the problem such as a real virus, a secret corporate installed keylogger, any anti-virus software, clipboard and "hot key" utility software, screen recording utils etc etc

 

- intermittent hard drive sector read issue - perhaps run full sector disk scan and also ye old "sfc /scannow" command

  • I've got the latest VS updates installed.
  • I've got basically the same spec computer as everyone else in the office (Intel i5, 16GB ram, terabyte drive) The only difference between my hardware and everyone else's is I bought myself a decent Logitech keyboard and mouse to replace the crappy ones that came with the machine. All machines are running Windows 10 64bit. It's a massive project, not exactly sure what it all contains. It's definitely got console applications in it. It's a website with multiple front ends, service layers backends etc. Millions of lines of code.
  • I've got hyper-v enabled on my machine.
  • Will try there too.

  • I do have VS extensions but the issue occurs in safe mode and (not due to this issue) a fresh Windows install with a fresh VS install with no extensions added.
  • The only thing I have that monitors keystrokes would be an autohotkey script that I use to quickly launch a bunch of console applications for various websites I'm testing. Also replaces @@ with my email address (because I'm lazy :-) )
  • I haven't tried a disk scan. Will do one over the weekend.

  • If you copy your project to another computer in the office at the time of crash, it does not have the issue?

  • uninstall autohotkey and reboot when you have the issue
  • also disable WIndows Defender or any Anti-Virus Software temporarily when you have the issue

 

  • I haven't tried a disk scan. Will do one over the weekend.
  • also the "sfc /scannow" quickly identifies any fundamental O/S corruptions

 

- in addition to above comments, you could temporarily install a second VS2015 into a fresh Windows VM which would give you more control over making a bare minimum config that can load the files from the project that are suspect. Also don't sign into VS as yourself to avoid pulling in any settings from the cloud on a fresh install.

 

- also, is the project pulling in any stuff from Nuget? if so, can you provide a list?

 

- after all of the above, we still have the option of debugging VS2015 itself as the problem happens, but that removes all the Sherlock Holmes style fun of logically deducing the culprit :)

There is a tool here that removes whitespace and checks line endings etc. That tool as-is or some mod to it that also checks char ranges etc for unusual "somethings" might be useful.

I'm all out of ideas until more info is available.

    • Google reportedly set to lose two key Gemini and DeepMind researchers to Anthropic

      By Karthik Mudaliar · Posted

      Google reportedly set to lose two key Gemini and DeepMind researchers to Anthropic by Karthik Mudaliar Google is reportedly preparing to lose two more prominent artificial intelligence researchers, with Gemini contributors Jonas Adler and Alexander Pritzel planning to join rival AI developer Anthropic. According to a report from Bloomberg, both researchers are viewed internally as important contributors to Google’s flagship Gemini model family. Adler worked on Google’s AI coding efforts, while Pritzel was involved in the process used to train AI systems. Neither company has publicly confirmed the moves. The report also does not say when the researchers will formally leave Google or what positions they will hold at Anthropic. Training a large AI model requires decisions covering its architecture, data preparation, distributed computing infrastructure, and post-training methods that shape how the finished system behaves. Researchers with experience operating at the scale of Gemini are consequently difficult to replace quickly. Both Adler and Pritzel have previously contributed to Google DeepMind’s scientific research as well. They are listed among the authors of the company’s work on expanding AlphaFold protein-structure predictions across entire proteomes, alongside AlphaFold researchers including John Jumper. The reported departures arrive shortly after another important change within Google’s Gemini organization. Gemini co-lead Noam Shazeer is leaving Google for OpenAI, after returning to the search company in 2024 through its deal with Character.AI. Shazeer is particularly well known as one of the authors of the Transformer paper, whose architecture became the foundation for most modern large language models. Anthropic, meanwhile, has been recruiting recognizable figures from other leading laboratories. OpenAI co-founder and former Tesla AI director Andrej Karpathy joined Anthropic’s pre-training team in May. His move, followed by the reported recruitment of several Google researchers, suggests Anthropic is strengthening the research teams responsible for the core capabilities of future Claude models rather than concentrating solely on product and enterprise sales. The competition is complicated by the companies’ extensive commercial relationships. Anthropic competes directly with Google’s Gemini models, but it also relies on Google as an infrastructure partner. In April, Anthropic announced an expanded agreement with Google and Broadcom covering multiple gigawatts of next-generation Tensor Processing Unit capacity. TPUs are Google-designed accelerators used to train and run large AI models. via Bloomberg

    • Google adds built-in computer control to Gemini 3.5 flash

      By Karthik Mudaliar · Posted

      Google adds built-in computer control to Gemini 3.5 flash by Karthik Mudaliar Google has added Computer Use as a built-in tool in Gemini 3.5 Flash, giving developers a single model that can reason about a task and operate graphical interfaces across browsers, mobile devices, and desktop environments. The feature is available through the Gemini API and Google’s Gemini Enterprise Agent Platform, although it remains a preview feature for now. Computer Use enables an AI agent to examine screenshots and return actions such as mouse clicks, scrolling, and keyboard input. A developer’s application must execute those actions, capture the resulting screen, and send it back to Gemini, creating a continuous loop until the task is completed. Google says the integration can be used for activities including repetitive form filling, application testing, research across multiple websites, and longer enterprise workflows. Gemini 3.5 Flash can work with browser, mobile, and desktop environments, whereas Google’s earlier standalone Computer Use model was primarily positioned around browser interaction. The main change is consolidation. Computer control was previously offered through the separate Gemini 2.5 Computer Use preview model. As Neowin reported when that model was introduced, it was designed to interpret a visual interface and generate actions without requiring a website-specific API. Google later brought Computer Use to preview versions of Gemini 3 Pro and Gemini 3 Flash in January 2026. The latest release now incorporates the tool into the stable Gemini 3.5 Flash model rather than requiring developers to select a specialized model solely for interface automation. Gemini 3.5 Flash itself was announced in May as Google’s latest fast model for coding and multi-step agent workflows. It supports a one-million-token input context window and up to 65,000 output tokens, along with adjustable thinking levels that let developers trade additional reasoning for lower latency and cost. Google also added that Gemini 3.5 Flash received targeted adversarial training for computer-use scenarios. The company is also offering safeguards that can require user confirmation before sensitive or irreversible actions and automatically stop a workflow when suspected prompt injection is detected. Its developer documentation describes configurable protections for areas such as financial transactions and changes to sensitive records. Google isn't the first to bring Computer Use to its platform. Anthropic has made computer control available through Claude, while OpenAI has continued improving computer-use performance in its recent models. Microsoft has also applied the concept to business workflows, including a Computer Use capability for the Researcher agent in Microsoft 365 Copilot.

      After I installed KB5095093, the volume on my ARM laptop won't go above 20%. It's stuck on the hearing protection level, which is pretty much useless if you want to listen to anything. I rolled back.
