I am creating an android app in visual studio 2015. While building the solution I am getting this error :
The specified task executable "csc.exe" could not be run. Could not load file or assembly 'Microsoft.CodeAnalysis, Version=1.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I have update my visual studio as well. but nothing is working for me.
Here is snapshot of error:

I get several errors when trying to edit my build definition. This has worked fine before, but I suspect that installing Visual Studio 2015 has messed things up.
History:
First I had Visual Studio 2013 Ultimate. At this time there were no problems
Recently I installed Visual Studio 2015 Professional.
For licensing reasons, I had to remove VS 2013 Ultimate and install VS 2013 Professional instead.
In VS 2013 Professional-> Team Explorer->Builds I now get an error when I edit my build definition. I suspect that the installation/reinstallation is the cause.
Under Process->Items to build I click the add button and get this error message:
[A]Microsoft.TeamFoundation.Build.Workflow.Activities.BuildSettings cannot be cast to [B]Microsoft.TeamFoundation.Build.Workflow.Activities.BuildSettings. Type A originates from 'Microsoft.TeamFoundation.Build.Workflow, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' in the context 'Default' at location 'C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\Microsoft.TeamFoundation.Build.Workflow\v4.0_10.0.0.0__b03f5f7f11d50a3a\Microsoft.TeamFoundation.Build.Workflow.dll'.

You can also try to:
Clean the Cache folder on client computer. The folder path is: C:\Users\username\AppData\Local\Microsoft\Team Foundation\x.0\Cache. (x is the TFS version)
Clean the Cache folder on Server machine. The folder path is: C:\ProgramData\Microsoft\Team Foundation\Web Access\Cache_v10.0
Try resetting settings and add-in settings (devenv /ResetSettings) and (devenv /ResetSkipPkgs), try rebuilding all templates (devenv /setup).
I am using Visual Studio 2013 SP1.
After installing Roslyn I wanted to play with the samples. In the samples folder there is a project called MakeConstCS. So I hit F5, the experimental VS env is loaded. Then I create a new project and boom.
Normal Build Error incomplete Could not load file or assembly 'Microsoft.VisualStudio.LanguageServices.CSharp, Version=0.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I get the same error when I try File->New->Project->Templates->C#->Roslyn->CodeRefactoring->F5
Any idea why this happens?
You need to install Roslyn into your VS experimental hive. This is listed in the Readme, and the SDK includes an exe to do so.
Correct way to reinstall Roslyn:
Uninstall all the Roslyn extensions
Delete %LocalAppData%\Microsoft\VisualStudio\12.0Roslyn
Using regedit delete HKCU\Software\Microsoft\visualStudio\12.0Roslyn and 12.0Roslyn_Config
Run Install Roslyn Preview into Roslyn Experimental Hive.exe
Run Roslyn End User Preview.vsix
Run Roslyn SDK Project Templates.vsix
Run Roslyn Syntax Visualizer.vsix
For debugging with VisualStudio2013
Check the project file entry and use the correct version of your VS instance:
<VisualStudioVersion Condition="'$(VisualStudioVersion)' == '">12.0</VisualStudioVersion>
Ever since my latest windows update, (which system restore is failing to undo) I can't load any projects with visual studio 2010. The project are greyed out (unavailable) and when I try to reload them I get the error:
C:\Users\Benoit\Documents\Visual Studio 2010\Projects\Test123\Test123\Test123.csproj : error : Unable to read the project file 'Test123.csproj'. Could not load file or assembly 'Microsoft.Build, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.
I tried creating new projects: same error
I tried creating different type of projects (command prompt, silverlight, windows phone): same error
Deleting the .suo and .user files did not change anything
I did not move the projects
Using Visual Studio 2010 with Windows Vista
It looks like the Global Assembly Cache (GAC) is messed up, or possibly the update has done something with the Microsoft.Build assembly file itself.
Try repairing .NET 4.0, and if that does not work you can try completely uninstalling and reinstalling the framework.
Everytime i try to open Visual Studios 2012, an error message displays
" Could not load file or assembly 'PresentationFramework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e25' or one of its dependencies. The system cannot find the file specified."
Any idea what is wrong? How to fix this?
Try to Uninstall the Visual Studio that you have and download it from http://www.microsoft.com/visualstudio/esn/2013-preview. It works for me perfectly.
