Below, you'll find ContextKeeper, a session manager for Visual Studio, compared to alternatives.

All extensions included in the comparison work with Visual Studio 2022. I've included free extensions, with the exception of Task Canvas, which is a paid one. I've invested several hours testing Favorite Documents, Workspace Manager, and Task Canvas to get a clearer picture of how they all stack up against ContextKeeper

Task Canvas

I must say, I'm a bit surprised by how Task Canvas, the only paid competitor, performed in the comparison. It was built with a different workflow in mind, which is why it lacks in certain areas. However, it's still quite powerful and presents an interesting concept with its independent task canvas (separate, physical tab). Kudos to Sergey for trying something different. I'll take a closer look to see if there are any elements from this concept that could add additional value to ContextKeeper. What are your thoughts on this?

Favorite Documents

It appears that the most popular extension is based on the simple VS API - VsShellUtilities.OpenDocument(). Unfortunately, it lacks more sophisticated use cases. Nonetheless, it's still better than relying solely on Visual Studio's default state engine and the inherently flawed .suo file.

Workspace Manager

The spiritual successor to the (broken) approach of Save All the Tabs, utilizing the IVsUIShellDocumentWindowMgr.ReopenDocumentWindows() API. Unfortunately it is nothing more than wrapper for the default Visual Studio state engine, which which has had persistent, unresolved issues for years. It's unreliable, sometimes functioning properly but often failing. My experience with it has been similar to Save All the Tabs, which I tried using with mixed success in the past.

The fail of the Save All the Tabs extension, to deliver a stable and reliable restore mechanism, really push me to work on the a truly independent session restore engine. I distinctly recall my thought process during that time -

If it doesn't work, I'll at least give it a shot and try to build it. There's nothing wrong with failing, but if I succeed, it will be a big deal one day! I will try to make it the state-of-the-art session manager that Visual Studio has never had but always deserved.

Later, the context engine has become the heart of ContextKeeper. It was entirely written from scratch, and it is fully independent from Visual Studio session restore API. It is rock solid, and works in VS 2022, including olders versions VS 2019/2017/2015. It has taken thousands of hours and years of work to bring it to a state where it is a true pleasure and an enjoyable experience to use, and to have the session manager that Visual Studio has always deserved. 🚀 Cause there ain't room for more than one King 👑 in this town.
