Can't build .NET Core projects after update

Question

I can't seem to find anyone with this same issue and it had me pulling out my hair for hours. I am working on a .net core project with a team of people. I realize my version was quite a bit out of date and upgraded to version 1.0.4. However, since the update, I can no longer build or run the project without errors.

C:\Program Files\dotnet\sdk\1.0.4\Sdks\Microsoft.NET.Sdk\build\Microsoft.PackageDependancyResolution.targets(154,5): error : Assets file 'C:\Users\ZL\Documents\lynx\lynx%20project\src\Lynx.Web\obj\project.assets.json' not found. Run a NuGet package restore to generate this file. [C:\Users\ZL\Documents\lynx\lynx%20project\src\Lynx.Web\Lynx.Web.csproj] obj\Debug\netcoreapp1.1\Lynx.Web.AssembleyInfo.cs(6,12): error CS0246: The type or namespace name 'System' could not be found (are you missing a directive or an assembly reference?)

[C:\Users\ZL\Documents\lynx\lynx%20project\src\Lynx.Web\Lynx.Web.csproj]

These files exist and look fine. I have run a dotnet restore and dotnet clean. I tried wiping out the obj and bin folders and regenerating them. I wiped our NuGet cache. I tried uninstalling .NET Core and reinstalling it. I even blew away my code completely and pulled a fresh version from git. The other team members can build the code fine and it works on other machines just not my windows 10 machine. It seems like a dotnet restore should fix it, and everywhere I found when researching similar problems that was the fix. Some sort of version of something is out of wack but I can't figure it out. Is there something I need to update that I'm missing?

Thanks in advance.

Answer 1

I was able to finally figure it out. On my machine, the project was in the folder lynx project, however, somehow when I pulled code or updated my version that folder name changed to lynx%20project. Thats why it was unable to find any files. I jumped in and changed the directory name and it was fixed. Thank you all who tried to help. Hopefully this will save some poor dev some time in the future.
