On today's #VSToolbox replay episode, we get a behind the scenes look at how performance is measured and what improvements were made in #VisualStudio 2026. Drop in, msft.it/63329tmThT

If you fire off windows feedback i will make sure lands on the right desk.

This is my own opinion and not Windows.

This feature will never work on a developer machine as "by design" devs build untusted binaries.

I've also reverse engineered events as we run into it, too, as greatly increases the cost of things that load lots of binaries.

It turns off after 48 hours if it sees untrusted binaries, but you can fast track by switching it off directly via Smart App Control in Settings.

Been using it since it was released. Rock solid and performance is great. It’s my new daily driver.

If you aren't using the new insiders build, you are missing out:

We've been working for a while on a vision of what Visual Studio looks like in the future, and first insiders build of 2026 represents one of our first steps towards that.

On top of being gorgeous with its modern Fluent UI, this build one of the fastest releases we've released, with more to come.

This is my fault. I explain here: www.reddit.com/r/dotnet/com...

The startup time on the new Visual Studio 2026 preview is really impressive. Even for a very large 100+ project solution, it opens in just a few seconds.

I'm super glad you noticed, we've been working hard on it. :)

Can you expand on the "accidentally installed the wrong version"?

Visual Studio can update its reference to Documents in options, need to uninstall/reinstall.

Probably puts us at a severe disadvantage, but I am interested in where you thinking we are are slower.

In what scenarios Jimmy?

This performance boost is not by moving to .NET Core.

Glad you like! We're using it daily too as our main IDE.

Gotta say that in other news - I’m really enjoying the new #vs2026 insiders version.

Not one crash and now it’s my primary IDE . Seems snappier and cleaner. Great job #VisualStudio team.

And shout out to #SSMS team! V21 is breath of fresh air.

Will get to it, writing it up is taking away from the doing more. :)

I haven't posted much for a while as I've been heads down working with the Visual Studio team to deliver all the performance and other goodness in this one.

ie the operator == doesn't take nullable parameters?

04.08.2025 12:30 πŸ‘ 0 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

My first thought was the comparing value type against null warning Roslyn added over the old compiler, but I don't think you can bang (!) your way out of that.

Next thought is maybe R# or something complaining about comparing a non-nullable value against null and the bangs silence it?

If my brain thinks its important, usually it can't stop thinking about it until I've literally done or sent off an email about it. I've not found anything that works for me, let me know me if you find something,
