So rather than using this post to talk about a bunch of the changes, I want to share a story about hunting down some memory issues in VS. Both had reached out to us with saying they were having problems with sluggishness and stability when dealing with solution files containing s of projects and millions of files.

File write attributes msdn subscriptions customer, for example, had a solution file with projects all.

NETwhich was making VS hang and crash from anywhere within five to 60 minutes of opening a solution. Another customer had a solution file with projects mostly. Though this project would load successfully, it was consuming a lot of CPU cycles, causing the IDE to be very sluggish while editing code, and the customer also experienced random crashes.

On the surface, these might look like very related issues. As we talked with the customers and debugged their solutions, it became clear that the root causes were pretty different. Here are some of the things we learned and what we changed: We had tuned the algorithm for releasing cached project information to one particular shape of solutions basically mid-sized.

NET-only solutions Some cached project information was simply retained for too long, regardless of the solution. VS enabled high-impact features like full code scanning in all cases, rather than allowing users to select whether they wanted them on or not.

VS would sometimes promote metadata references to project-to-project P2P references for a better experience; however, for some customers those with complex P2P reference chains, or with post-build steps that modify binariesthis was actually degrading performance.

These problems turned out to be quite complex, often involving engineers from five or six feature teams to diagnose and fix them. I want to take a second here to thank both of these customers you know who you are for their patience and willingness to let us take a look at their projects.

All of these fixes and more are in Update 3; please take a look at the release notes and known issues for the full list. Thanks to some of you early adopters, we were able to fix or offer workarounds for some installation issues that were affecting a small percentage of users, including the inability to install Update 3 and not being able to create or load UWP projects.

Other fixes to other product issues are in the works and will be available soon. Please refer to the known issues for details. A new patch is now available to apply on top of Update 3.

There are a known set of attributes you can change using the FileAttribute properties. What you would normally do is provide some information at . FILE_ATTRIBUTE_ARCHIVE is just a file attribute (can look at using Explorer).

Turning on this attribute just marks the file as needing to be archived. Best example of this I can think of is Source Control.
