For me (Unity 2020.x and VS19) this happens quite often.
Simply close VS and in Unity &gt; Edit &gt; Preferences &gt; External Tools
Click on &quot;Regenerate project files&quot; (you don't need to check anything else, just click the button)
Start VS again, and it should work as normal.

To prevent this from happening:
When there are compiling errors in your code, don't double click on Unity Debug Log line, which opens VS at the line that threw the error, but it messes with the project files.
Regenerating the project files under Unity &gt; Preferences &gt; External Tools &gt; Regenerate Project Files. Also make sure that Visual Studio is set under external tools, as well as all the Unity dependencies are correctly installed via the Visual Studio installer.
<a href="https://i.stack.imgur.com/zJC0N.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/zJC0N.jpg" alt="enter image description here" /></a>
Visual Studio will prompt you to reload the project, optionally rebuild your entire solution in VS and restart both Unity and VS.

This is a quite common issue when using Unity. Me and my colleges have experienced this a couple of times each month. It usually automatically &quot;repairs itself&quot; after restarting VS/Unity or in worst case rebooting the computer.
Now, I've got this problem again with latest VS2019. I've tried:
<ul>
<li>Generate a new clean project</li>
<li>Rebooting</li>
<li>Regenerated all visual studio files</li>
<li>Reinstall VS 2019 (clean)</li>
<li>Reinstall Unity (It is clean - I'm only using one! editor version)</li>
<li>All the above suggestions</li>
</ul>
Are there any network-related issue to this or how does the attach to Unity works ? Can I check some log-files related to this?
Last time this happened to me, I needed to reinstall Windows. I might be in that situation again.

Normally just restarting visual studio is sufficient, this issue was addressed and fixed by MS in VS around early december. Previously it happened each time you made a new script file.

Make sure you have installed the latest visual studio patch, as well as the "visual studio tools for unity"

I choose Enable debugging for all projects option.
I hope, It will help someone.

I'm using Visual Studio with Unity. In general in VS I can simply click &quot;Attach to Unity&quot; and it will build the solution and indeed attach to Unity.
Sometimes, however, a project loses the &quot;ability&quot; to do so, what means that suddenly clicking the button will only build the solution and not attach to Unity.
I really would like to know what's happening there as I'm not aware of doing anything that could result in such a behaviour. 
There are some parameters that might have an effect:
<ul>
<li>it happens only for some Unity projects: a project is either &quot;infected&quot; or it happens never (on my watch)</li>
<li>if it starts happening it will always happen until I reboot the PC (closing VS and Unity is not enough)</li>
</ul>

Visual Studio loses ability to attach to Unity, why?
