Resolution of Error: “This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them. For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is ..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props.”

Today I faced this issue during compilation of an asp.net 4.5.2  webforms app on Visual Studio 2015 Enterprise which was built few months back using Visual Studio 2013 Update 4  environment from VS online(TFS).

Problem Statement:

The error was highlighted during building of the project.

“This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is ..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props.”

Resolution: 

The error comes due to obsolete .nuget packages & wrong path indicated on app.csproj or .vbproj file. So, in order to solve the issue,

1. First clear all folders under ‘Packages’ directory of project main directory.

2. Restart the solution on VS & click on ‘manage nuget package’ from project solution explorer. Update all .nuget packages to latest version.

 

3. Open the project.csproj / .vbproj file on any text editor & replace the line with the appropriate line of the ‘Microsoft.Net.Compilers.1.1.1’ available in your project directory.

4. Don’t forget to comment out the following block in the project.csproj/vbproj file like as the screenshot.
