Because "utility methods or object extensions living in assemblies that could be added as a reference and that could be used throughout other solutions" should be the vast majority of your code.
Your data layer should be in a separate assembly because you'll be using it in the public facing website and on your intranet admin tool.
Your business logic should be in a separate assembly, because you'll be using it on the website, the desktop app, the command-line tool, and the mobile app.
Truth,
James

Reusability. You can reuse the assemblies in another program without having to import all that code. Better yet, you can easily reuse only part of the code, picking and choosing which assemblies you need.
Had to do exactly the above recently. We were able to leave out the parts of the code that required Windows UI libraries that don't exist on Linux yet through judicious choice of assemblies.
We can program with only 1's, but if all you've got are zeros, you've got nothing.

Cross-platform considerations are few and far between. I haven't had to write "cross-platform" code since 1989 using C++, and even then, we abandoned the effort after one application, even though (I thought) it turned out well.

I used to be of the camp to have many projects in a solution, thinking of allowing for maximum re-usability of ALL the components, including the following:
- Entity Types
- Repository Types
- Business Logic Types
- Data Transfer Object Types
- Web Application(s)
- Desktop Application(s)
Nowadays I structure my solution based on my designed deployment model. I try to work towards minimizing the number of projects, and currently my model is like the following:
- Desktop Application Project
- Desktop Application Installer Project
- Web Application Project
- Web Application Installer Project
- Business Logic Public Contracts Project
- Business Logic Platform Project(s)
For the business logic public contracts library, this project would contain as much business logic as I can stuff in a platform agnostic manner (in a portable class library, for example). Typically DTOs are placed here, alongside public types that contain re-usable business logic.
The platform-specific projects utilize the public contracts project. These kinds of projects will actually contain the database types, and will translate the DTOs to the underlying platform-specific data types.

Namespaces relates to the logical organisation of the code.
Assemblies relates to deployment, and can be governed by things like a plugin architecture, need for patch updates, versioning, reuse between different applications etc.
That's two different things, just like in UML where you can have both a logical view and a deployment view.

At some point, the set of folders or namespaces cries out (to me) for its own DLL ... as when I'm dealing with unique hardware devices or third-party APIs.
One also cannot have circular references with DLLs ... helps with keeping your "subject libraries" pure(r).
(Finally, limits my ability to blow my foot off with a hasty "project-wide" code change).

I come at this issue from an SCM viewpoint and while I think there are valid arguments to both separation and collapse, I tend to see many development efforts where the separation was based on how easy Visual Studio makes it. If the developers have discipline, this isn't necessarily a bad thing, but if not, you can quickly get spaghetti code.
I personally believe that all other things being equal, fewer artifacts is better. There are circumstances where they should split, but I default to not creating an extra assembly.
I'd recommend reading the 'White Book' Partitioning code base through .NET assemblies and Visual Studio projects found here:

The only point of multiple assemblies is if you want to use a part or parts of the projects in another environments. That is using shared libraries the way they've been used for decades now. Another reason would be if you want to run that stuff in a scalable cluster. One assembly does X, mutliple copies of the other assembly do Y and they communicate via some sort of IPC or network.
Outside of creating libraries because I actually need a library and outside of clusters, I always go with folders & namespaces. Because there's no reason to break up a single-responsibility project into multiple binaries. It only makes deployment more complex (albeit not much more) without any benefits.

Last night, we started a week long kid's program called "Ocean Commotion".
All of the leaders/adults are supposed to have 'ocean' related names.
My co-workers are: Sally Seaweed, etc.
I chose Sid Fishes... only a select group get it.

In our lovely Waldorf-ee community, we get all sorts of amusing names. For example, A Mrs. Blue gave her daughter the first name of Sky.

A company I worked for employed a young man called Richard Head (what were his parents thinking?). And another one had a young lady called Annette Curtain. There was also a lady called Ann Winters, we speculated that she sold lingerie to Eskimos.

I know a Richard Head.
And also a James James. Think his parents had more of a screw loose.

A friend's name is "Ken Doll" (he's older than the Mattel usage)
And I once met "Vinnie Barbarino" who had the name first (From "Welcome Back, Kotter"[^])

I'm trying to download a service pack and Microsoft wants me to sign in. Yet the signin page redirects back to itself a couple of times and then says it can't do it. I try and go to Microsoft.com - just to view the homepage! - and it's trying to sign me in and fails with "Something went wrong and we can't sign you in right now. Please try again later" (and has since last night).
Something wrong with login.live.com or is it just me?
cheers

First go to the reset for your microsoft login account username and password page.second you choose reason for password reset.third, Enter the email id for microfost addresss that email id end page hotmail.com or livemail.com.fourth, to have seen the screen for login character then click next. finally , If you've added security info to your account, we'll send a one-time code to the alternate phone number or email address you gave us. After you enter that code on the next screen, you'll be able to make a new password.
