I have looked through the existing posts and have not found one that addresses this issue.
I am trying my hand at Xamarin.Forms in Visual Studio 2019. I am trying to follow along with a couple of online videos and books, but am unable to because I do not see the same options on my system for creating the project as the tutorials have.
Specifically, the tutorials are beginning with a "Shell" template for the Mobile App project, and my screen does not have this option.
I am running on Windows 10 Pro; Visual Studio 2019 version 16.9.4; Xamarin Templates version 16.9.72 (426ebf6).
The current Flyout and Tabbed template are in fact both based on Shell, they have replaced respectively the old MasterDetail (FlyoutPage) and Tabbed (TabbedPage) templates. I guess it a Xamarin.Forms team choice, to maybe encourage developers to move to the new Shell.
So if the tutorial you are following is using:
The old Tabbed template, you need to select the Blank template and look at TabbedPage.
The old MasterDetail template, you need to select the Blank template and look at FlyoutPage.
The old Shell template, you can choose either Flyout or Tabbed template.
The type Shell kind of combines both FlyoutPage and TabbedPage. If you are still confused take a look at the documentation, also Xamarin Form Shell: Flyout v/s TabBar may help.
I am developing an app using the ArcGIS Runtime SDK for .NET in Visual Studio Community 2017, currently set to Debug configuration.
There are these two black boxes/squares with numbers in them, one floats top left of the app window and another one floats top right of my desktop.
I have outline the one floating in the app in red in the following image:
Black box floating in app window with ArcGIS Runtime app for .NET
I assume its some sort of debug information specific to the ArcGIS SDK but searching online has yielded no results and the documentation on the ESRI website does not seem to make mention of it.
Note: It does not display when running the app on an android device, only when running the UWP version.
I would like to know what they are (1) and (2) How to enable and disable them.
That is a debug feature provided by UWP & Visual Studio. There are two black bars in the screenshot you posted:
In the center is the XAML debugging tools. You can disable this by going to Tools> Options> Debugging> General and unchecking 'Enable UI Debugging Tools for XAML'.
On the left is the framerate counter. You can disable this in code:
in App.xaml.cs (within the UWP project):
#if DEBUG
if (System.Diagnostics.Debugger.IsAttached)
{
DebugSettings.EnableFrameRateCounter = false;
}
#endif
Note that the above code already exists in that file, but EnableFrameRateCounter is set to true.
Also note that those tools only appear in debug mode.

I have tried to install same, but no success. Getting below error.
Could not get information from repository: http://addins.monodevelop.com/Alpha/Mac/6.1.5/main.mrep.
Xamarin studio Version (On Mac )
Version: 6.1.5 (Build 0)
Try manually downloading the .mpack file and add it. You can grab the file from here: http://addins.monodevelop.com/Project/Index/226
Once you have the .mpack downloaded, follow these steps to install it from Xamarin Studio.
Go to the Xamarin Studio -> Add-ins menu
Click the "Install from file..." button on the lower left.
Select the .mpack file you downloaded
Press "Open" to select it
I installed it using the method therealjohn outlined. However, the XS version is not as good as the Visual Studio one (Windows version). In XS, when you create a new PrismContentPage, it only adds the page and wires it up for you. On Windows, it creates the page, wires it up for you, and creates the associated ViewModel in the correct location with the correct base class. In some cases it might register your view and viewmodels with your DI container automatically.
VS 2010 Toolbox in ASP.NET application development (design mode or source) is not showing all controls (showing HTML and reporting ones), I can see all by right click (Show all) but they are greyed out or inactive.
I have used devnev.exe in VS Command line to reset, have reinstalled VS, have deleted the four hidden files in C:\Users\Ramzan\AppData\Local\Microsoft\VisualStudio\10.0 with extension .tbd, all in vain.
This thing is driving me mad. I have another machine and everything works fine there.
Any help much appreciated.
Don't know if this applies; but I had all controls in the toolbox disabled; you could see them but they were disabled - This in Visual Studio 2010. I right click on a toolbox item then reset toolbox and then they are enabled. Note that you may lose any custom controls you added.
Probably your project is RUNNING. STOP the project then your toolbar items will become enable.
Right click in toolbox and remove check from "SHOW ALL" (if checked)
This was driving me crazy for a pair of days. In the choose items menu my 3rd party controls (CrystalReportsViewer) were checked. Reset toolbox did nothing to enable them. My solution was changing the target framework from .NET Framework 4 Client Profile to the full version .NET Framework 4, seems the client profile which is a subset of the version optimized for client applications does not support my controls or just using references to other 3rd party .dll librarys. This issue should only be for .NET 3.5 and 4.0, Client Profile is discontinued for .NET 4.5
I had the same problem and fixed it now after 3 days:
reset toolbox (not worked)
close and reopen the solution (not worked)
close and reopen the VS (it worked!)
After a long time googling , and mostly all answers - revolving around
Reset Toolbar
Delete .tbd files from C:\Users(your user)\AppData\Local\Microsoft\VisualStudio\11.0
Using devenv.exe /SafeMode & devenv.exe /ResetSettings.
None of them working out for me, making me more sick.
There is something I did which worked and thought it's worth sharing if it helps someone.
I followed all of the above steps, failing . I did Step 1 & 2 with my project (in VS 2012) open and
Right Click on Toolbox > Choose Items > Pressed Reset > ok.
Then again, Right Click on Toolbox > Add Tab > 'gave it some name' > then again
Reset Toolbox
There was some screen flash/flickering - some loading .
And to my surprise the Grey life ( grey controls ) were now available .
Hope this helps someone like me! :)
This worked for me..
How to completely reset the Toolbox and enable Visual Studio to rebuild it from scratch
Close Visual Studio;
Open the "c:\Users\\AppData\Local\Microsoft\VisualStudio\10.0" (Windows 7) folder and remove all the .TBD files;
Run the "regedit" tool. For this click the "Run" item in the Start menu and type "regedit" without quotation marks;
Find the "HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\ToolboxControlsInstaller_AssemblyFoldersExCache" and "HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\ToolboxControlsInstallerCache" keys;
Remove everything from these keys leaving them empty;
Run Visual Studio again and wait until it recreates all items in the Toolbox.
If you are working in WPF application and your Xaml is opened with xml, then make sure you right click and view designer, to get your toolbox controls enabled. (Toolbox controls seem to be active(enabled) only in designer mode). At least that was the case with me.
I know this is old but I just encountered the same problem and here is what I did:
Click on Data Flow
Right click anywhere in that window
Select SSIS Toolbox.
Hope this would help someone.
I worked for me doing the following steps:
Reset Toolbox (Right click in Toolbox->Reset Toolbox)
Add a new tab with any name (Right click in Toolbox->Add Tab)
Reset Toolbox (Right click in Toolbox->Reset Toolbox)
What helped me was changing Project type from Windows Application to Class Library - then (after re-build and reopen...) I got all Controls Enabled.
What did it for me on a custom control was to first remove the control from my base project. Then I had to pull up the custom control as a separate solution by itself and recompile it. I had to make sure that that it was compiled as a class library and not as a windows application. I had to make sure that it was compiled with Framework 4 (same as my base solution) and that all sub controls and projects were also using framework 4. Once I got all of those things sorted out I went back to my base project and added the newly compiled control and sure enough it was enabled.
I hope this helps someone.
I tried all the above mentioned still not working for me. I was working on a windows application after that I have started the web application coding on visual studio after that whenever I was opening the Visual studio this problem was occurring. I am using Visual studio 2015. So what I did, I have right-click inside the toolbox panel and selected 'choose option' then under '.Net framework' components tab I have checked all check boxes for which assembly name is 'System.windows.forms' It is working for me now.
Make sure the currently opened solution platform actually supports controls you need.
My problem was, for example, that I tried to add 'SqlConnection' control to .NET 6.0 application.
Once, I created a '.NET Framework Windows Form' project 'SqlConnection' control became available
Installed ASP.NET MVC
Created Project
About 2 minutes into project (not even running / building / debugging)
Visual Studio 2008 will no longer take focus from the mouse.
Click on visual studio - seems like there is a modal open somewhere.
Windows + D... no modal
Can't see VS2008 in alt tab
Only way to get it back is task manager.
Happens with multiple solutions / projects...alawys ASP.NET MVC
I'd try this:
Press Alt + Space
If you see a menu appear that has Move as an option, select Move
Press any arrow key
Move your mouse around.
Hopefully a modal dialog will appear.
I really really hate to ask this, but did you try rebooting?
