Delete all the .csproj.user files

which were full of null characters, and also these

C:\Users\UserName\AppData\Local\Temp\

.NETFramework,Version=v4.0.AssemblyAttributes.cs .NETFramework,Version=v4.5.AssemblyAttributes.cs .NETFramework,Version=v4.5.2.AssemblyAttributes.cs

Hey  I have the same issue on Mac working on a Cocoa C  solution   But I solved it     It always say that the root element is missing so it cannot load my C  project file   I have the 2017 Visual Studio Mac Community Edition  I finally managed to find a solution after several hours  painful     My solution is because the frameworks related to the Visual Studio are old or broken  I found this because I tried to create a new Mac solution by Cocoa and it said  failed to save the solution   Then  I tried to create an Android Solution and it is working fine  Go to your  Finder  and  Go  -   Go to a Folder  then go to the  Library Frameworks   I have deleted mono framework and frameworks related to Xamarin because I believe these Xamarin frameworks are broken   Then  uninstalled the Visual Studio and reinstalled it   Now everything works fine

This error can sometimes occur when you edit some Project Toolchain settings Atmel Studio 6 1 2730 SP2   In my case I tried to edit Project Properties   Toolchain   Linker   General settings with  All Configurations  selected in the Configuration  When I checked or unchecked a setting  a dialog with the error popped up  However  I found that I could make the same edits if I made them to only one build configuration at a time  i e  with only  Debug  or  Release  selected instead of  All Configurations    Interestingly  I later was able to edit the same Linker settings even with  All Configurations  selected  I don t know what changed in my project that made this possible

User · Answer

You will also get  root element is missing  when the BOM strikes     BOM   byte order mark  This is an extra character that gets added to the start of a file when it is saved with the wrong encoding  This can happen sometimes in Visual Studio when working with XML files  You can either code something to remove it from all your files  or if you know which file it is you can force visual studio to save it with a specific encoding  utf-8 or ascii IIRC      If you open the file in an editor other than VS  try notepad     you will see two funny characters before the  lt   xml declaration   To fix this in VS  open the file in VS and then depending on the version of VS   File   Advanced Save Options   choose an appropriate encoding File   Save As   keep the filename  click the drop-down arrow on the right side of the save button to select an encoding

In my case I upgraded to VS2017 and wanted to build all projects with MSBuild 4 with my build script  which had been using MSBuild 3 5 when we were using VS2015   That MSBuild upgrade appeared fine for the Windows desktop applications but the ones for Windows CE with compact framework would give me this confusing error  Reverting to MSBuild 3 5 for Windows CE projects fixed the issue for me   I did have the BOM in  csproj files by the way and removed them for all projects in a solution that would not build but that did not help
