Lots of green underlining after upgrade

Question

User882043084 posted

Hi, 

Since upgrading from VS2010 to VS2013 I'm getting a lot of green underlinging (warnings) of markup code.  The message says that known elements (content,  DropDownList etc) are not known elements when obviosly they are,  or that there might be a problem with the web.config which there is not. 

This just happened a few moments ago when no changes had been made to markup.  

I would just ignore this but it stops intelli-sense from working. 

Any ideas?

Take a look here: http://social.msdn.microsoft.com/Forums/vstudio/en-US/086495fd-2383-44b6-b4cb-89dfb3576f9e/visual-studio-2013-intellisense-issues?forum=visualstudiogeneral

 

Hi Paul,

Thank you for posting in the MSDN forum.

Just to make this issue clearly, what kind of app are you developing? Whether all projects have the same issue? 
Would you mind sharing me a simple sample? So I could repro this issue in my side with VS2013 RC.

If it is related to the language developing like VC# app, you could check the setting under 
TOOLS->Options->Text Editor->the specific language(C#) ->IntelliSense.

I have met a similar issue, the IntelliSense doesn’t work, but it works well after I reset my VS settings.

TOOLS->Import and Export Settings Wizard->Reset all settings->select “No, just reset settings, overwriting my current settings”
->Choose a Default Collection of settings. Check it again. Hope it could help.

hi, 

I haven't changed any settings since upgrading.  Sure I can go ahead and reset them all but this is odd, it's quite random and reports all is ok and 

then green underlines at different points during the day.

Hi yorky

I would just ignore this but it stops intelli-sense from working.

First check the 'Show completion list after a character is typed' in TOOLS -> Options -> Text Editor -> C# -> IntelliSense.

You can also consider resetting the user settings,

Reset Visual Studio user settings

If you need to restore default settings for your Visual Studio IDE, you can do the following

Open Visual Studio Command Prompt and enter the following command.

>devenv /ResetSettings

If you need to load the settings from a specific .vssettings file, you can use the below command

>devenv /ResetSettings SettingsFileName.vssettings

 Regards

Angie

Hi, 

I checked the options as you suggested and completion is indeed ticket.  Might just have to go with reding the settings although 

it seems a bit of a hammer to crack a nut. 

Thanks
