When I right click my project and go to Class Wizard I'm met with the following error:
"The solution's source code database may not have been opened. Please make sure the solution is not open in another copy of Visual Studio, and that its database file is not read only."
What I've tried so far:
Creating a new project
Restarting Visual Studio
Restarting PC
Repairing Visual Studio
Reinstalling Visual Studio
Installing MS SQL Server Compact 3.5
Deleting the folder: C:\Users\Jacob\AppData\Roaming\Microsoft\VisualStudio\14.0
None of these have had any effect, and I'm finding very few pages online where others have had this issue. I am totally at a loss on what to do next.
If anyone has any ideas, I would really appreciate them.
It turns out the problem here was actually caused by JetBrains Resharper C++, which I didn't consider could be the problem.
There seems to be no solution, however the program provides an alternative Class Wizard in the same menu.
Older versions of Android Studio had a Refresh option in the layout preview in the IDE, but in v2.2 it has vanished. I am finding repeatedly that I update drawable bitmaps in the project with updated files, that new version is not reflected automatically, and I do not see the preview. Problems like this are so common with Android Studio, it's such an utterly infuriating IDE and so flaky, despite the speed it is advancing.
Where did the refresh option go? I can't believe I'm having to actually ask this, but maybe I missed it somewhere obvious!
For some unknown reason the timeline graph shown on the summary page in Visual Studio 2012 is missing. This is the first time I use the profiler on a new computer and it just isn't there.
This is of course a huge issue as I am not able to filter which part of the run to profile. Typically I want to exclude initialization parts etc.
I've searched high and low for an option to enable/disable it but there seems to be none.
I tried to reinstall VS2012, but that did not help.
Has anyone experienced the same issue and does anyone know how to solve it?
I used to have R# 6 with VS2010 and it was great.
Now I installed yesterday R# 7.1 trial and my VS 2012 became slow to the point I really
want to uninstall R# despite all the heartache involved with it.
Any advices on how to troubleshoot this performance issue?
Please be more specific: what kind of projects do you work with, did you notice which particular actions are slow (for example, opening a solution, invoking code completion (IntelliSense) in JavaScript or something like this). Without details I can only give you these general advises:
Close Visual Studio, try to delete your solution caches (they are usually located near your *.sln file, in folder named like _ReSharper.), open Visual Studio again.
Try to temporaty disable/uninstall all other Visual Studio extensions/plugins.
Try ReSharper 8.0 EAP, maybe your issue is fixed there.
ReSharper has a feature that allows you to profile it (menu ReSharper | Help | Profile Visual Studio). If you know a reproducible slow action, you can invoke this feature, make this action and then send this performance snapshot to JetBrains support (http://www.jetbrains.com/support/resharper/) or open a bugreport at http://youtrack.jetbrains.net/. They could tell you which part of ReSharper is slow and how to disable that part.
I'm having real trouble when I try to use the IOS emulator from the visual studio. So I created a hello world app in VS using xamarin (latest stable version), I set the project as main project, and When I refresh the connexion with the mac, I can't select the device that should be shown in the selectList. The message is "No device attached" :
And if I try to use xamarin studio on the host mac, all is okay, the sample app builds on the iphone emulator:
Thanks to help me !
I know this question has already been answered, but i found it when i had a problem, and it did not help... but i did find the solution:
Under the debugging menu in VS2012, click on Configuration Manager
make sure that iPhone Simulator (or iPad, if you want) is set...
Default seems to be looking for a physical device...
hope this helps.
Are you sure the device is connected to the Mac and not the Windows machine? Have you tried debugging from that same device from Xamarin Studio on the Mac?
Had the same problem. Issue was when i loaded my solution, visual studio 2012 decided to choose a library project as the 'Startup project'.
Rt Clicked the ios project, chose 'Set as StartUp Project' and the device list was populated.
P.S: Visual Studio you should be old enough to figure this out by now.
When I ran into this problem, I had another instance of visual studio running which was connected to the Mac.
Apparently you can only have on VS instance connected at a time.
Check your server log in Visual Studio output window for some more clues:
Closing the other instance of Visual Studio allowed me to connect in the instance I wanted to debug in
I discovered something missing. For me, in Visual Studio 2013, for some reason they have removed Solution Platforms from the toolbar. This makes it impossible to switch from iPhone to iPhoneSimulator without opening Configuration Manager. So, to fix this.
Click TOOLS/Customize then select the 'Commands' tab then select the 'Toolbar:' radio button and click the dropdown to the right of it and select 'Standard' as the toolbar you're working on.
Now, click 'Add Command' and select 'Build' from the catagories on the left and then scroll down commands until you find 'Solution Platforms'. Select that one and click OK. Then click the 'Close' button. You will now see an additional dropdown next to the Solution Configurations dropdown on your Standard Toolbar.
This will allow you to easily switch from iPhoneSimulator and iPhone. Use iPhone when you want to plug in an actual device, and use iPhoneSimulator when you want to pick a simulated device.
Hope this helps somebody out. I too have spent lots of time trying to figure this one out when I went from a device and was trying to use the simulator instead.
Restarting of Visual Studio 2010 worked for me.
Different things worked for me (Windows 8.1 & Visual Studio 2013):
Restart Visual Studio
Set 'iPhoneSimulator' as platform (only working one)
In Properties - iOS Application change 'Deployment Target' version to some lower number (6.0 worked for me).
As well as checking you have the right startup project selected as per #Chamkila's answer, check that you haven't accidentally broken your project's Info.plist file by attempting to open it through Visual Studio.
