I am consistently getting this error with VS 2013:
Could not copy "C:\pagefile.sys" to "bin\roslyn\pagefile.sys". Exceeded retry count of 10. Failed. Unable to copy file "C:\pagefile.sys" to "bin\roslyn\pagefile.sys". The process cannot access the file
Please help me.
As indicated in this answer from Pramod's comment the problem stems from the Microsoft.CodeDom.Providers.DotNetCompilerPlatform nuget package, specifically upgrading from version 1.0.0 to 1.0.1.
For me however, downgrading using Visual Studio caused further build errors. To solve the problem I had to manually edit my csproj and packages.config files, removing all references to Microsoft.Net.Compilers and Microsoft.CodeDom.Providers.DotNetCompilerPlatform.
Specifically, this meant:
<Import Project="...
sections for all versions of both libraries (usually towards the beginning of the csproj)<Reference Include="...
sections for both versions of both libraries<Error Condition="!Exists(...
sections for both versions of both libraries from within the EnsureNuGetPackageBuildImports
target sectionMicrosoft.CodeDom.Providers.DotNetCompilerPlatform
and Microsoft.Net.Compilers
packages from the packages.config.I was then able to manage the projects nuget packages in VS and (in order) :
This solved the pagefile build error, and the runtime error which prompted me to try and upgrade in the first place.
I removed these packages from nuget package manager since I do not use them:
Microsoft.CodeDom.Providers.DotNetCompilerPlatform
Microsoft.Net.Compilers
Now everything works.
I've found a different solution to this error.
In my case I had been moving around a project within my solution (I put it in a subfolder). My references to packages (located in %solutionfolder%/packages
) in the project file were broken and I fixed them manually.
However, there are two supplement imports that I forgot:
<Import Project="..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" />
<Import Project="..\packages\Microsoft.Net.Compilers.1.0.0\build\Microsoft.Net.Compilers.props" Condition="Exists('..\packages\Microsoft.Net.Compilers.1.0.0\build\Microsoft.Net.Compilers.props')" />
I first updated the first one from ..\packages
to ..\..\packages
(lazy as I am). Building the project after that gave me the pagefile.sys error.
Updating the second import (same change: ..\packages
to ..\..\packages
) solved it for me.
Using the Clean Solution/Rebuild Solution steps resolved this issue for me.
Remove these two lines from .csproj file:
<Import Project="..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props" Condition="Exists('..\packages\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.1.0.0\build\Microsoft.CodeDom.Providers.DotNetCompilerPlatform.props')" />
<Import Project="..\packages\Microsoft.Net.Compilers.1.0.0\build\Microsoft.Net.Compilers.props" Condition="Exists('..\packages\Microsoft.Net.Compilers.1.0.0\build\Microsoft.Net.Compilers.props')" />
