The debug type field is greyed out as are the build buttons. I opened a folder in visual studio 2019 with my project and source code files. I have not installed any extensions yet either. I read somewhere to select a startup item but none of the items in the solution explorer are valid except for Gradebook.dll in the debug folder although that doesn't seem to do anything.
Did you try to click the run button or press F5.
If so it should prompt you to select CPU. Then, run it again and it should work.
If that doesn't work try going into "Program.cs" in the Solution Explorer and make sure the Application.Run line is there.
I recently upgraded to Windows 10 and Visual Studio 2019.
Prior to the upgrade, Visual Studio 2017 would always run as Administrator. I did not think much of this, but now that it is gone it is causing me problems.
The primary one is that it will not load my projects that use my local instance of IIS.
I usually launch Visual Studio from my start bar. Right now this goes like this:
Right click on the icon on the start bar and select my solution.
It loads and then I realize that the main project did not load.
Close visual studio, open as admin
Pick my solution and then it loads.
I would really like to only have to do #1 above. Is there someway I can edit the shortcut on the start bar to have it always launch as Administrator?
Turns out that Visual Studio uses different permissions when you click on the list of shortcut options it offers in the start menu. (IE to load a recent solution directly.)
Selecting the Properties->Advanced->"Run as Administrator" did not cause these to run as administrator.
But this did it:
Find devenv.exe (Visual Studio's executable)
Right Click on it and select "Troubleshoot Compatibility".
On the Program Compatibility Troubleshooter window, click on Troubleshoot Program
Check that the program requires additional permissions and click Next
On the next window, click on Test the program… and VS will open as administrator
Click next and then click on Yes, save these settings for this program
Now Visual Studio will ALWAYS run as administrator.

The document well is the feature in VS 2015 that closes a tab automatically when you switch to a different tab, unless you click the "Keep Open" button in the tab.
I find this very annoying, because often I will open a tab during debugging only to have it disappear after which I have to go hunting for the file again.
Is there a way to disable this feature, i.e. to keep all tabs open permanently, the way VS 2013 did?
I've looked in Tools\Options, and also did a quick web search, but couldn't find a way to do this.
Uncheck the Allow new files to be opened in the preview tab option:
When I was using Visual Studio 2010, I could just "Detach All" and the web site would continue to run and the browser wouldn't close. That would enable me to attach a different solution to debug a separately compiled library. Now all that's left is "Stop Debugging" and "Terminate All".
Although the website is still running in the background, I have to open a new browser window and navigate back where I was.
Is there some way to go back to the 2010 functionality?
Detach All is still available in VS 2012. If you don't have it under Debug in Main Menu then you may need to add it manually (right click on toolbar, select Customize.. from context menu).
When you start Visual Studio you get a start page with all the latest projects in a list.
But when you've opened and closed a project, how do you open that start page again?
(Without restarting VS)
Visual Studio 2010-2015
There's a menu item View -> Start Page
Additionally you can choose to keep the start page open when loading a project. There's a check box below the projects list for that.
(Tested in VS2010, VS2012, VS2013, VS2015)
In current versions, you can also use the Quick Launch (Ctrl+Q) to search for the command
(Just type "Start Page" in Quick Launch)
Visual Studio 2017
There's a menu item File -> Start Page
You can configure the behavior of the IDE on startup via Tools -> Options -> Environment -> Startup.
In Visual Studio 2017, the start page will open automatically when the solution is closed. As far as I know, this cannot be changed directly in the IDE but there's an extension that adds that feature. See this question on SO and this VSIX-Extension (but this will disable the start page completely - if you try to open it manually, it will be immediately closed automatically)
You also have the Start Page icon in the toolbar :
In VS2013 by default I do not see the "Start Page" command in the View menu but adding it was simple. The icon also looks different in VS2013.
Right click on the toolbar and choose Customize... at the bottom then go to Commands
Switch to Toolbar/Standard and then click the Add Command button an locate the View group on the left
Finally locate the Start Page item and click OK.
In VS 2017 the new location for viewing the start page
is under the 'file' menu. as appears in this link:
https://developercommunity.visualstudio.com/content/problem/4603/view-start-page-menu-item-is-missing.html
In VS 2017 it's in File->Start Page.
By now there is an extension exactly for that purpose:

I tried it an it works like a charme in VS 2015 :)
To get start page in visual studio 2017 Go to File -> Start Page
In case of Visual Studio 2019, go to File->Start Window.
It used to be automatic in VS2008 - Anything you had open outside of any solution/project (including the start page) would close when you opened a project/solution, then when closed that product/solution it went back to what was open before. That is how it should work, they broke it in VS2010. So all the prior VS users searching for the answer - there is none - technology continues to regress.
You can create custom shortcuts in VS under Tools > options > Environment > Keyboard.
makes it super easy to reopen the start page.
Here is my setup if you get confused
custom start page shortcut
In VS 2022 it's in Tools->Option->Environment->General->On Startup
