We are currently having problems while compiling a solution with MSBuild. The build fails randomly on the resource linking step inside the task "AL" which executes the "AL.exe" linker.
ALINK : error AL1019: Metadata failure while creating assembly -- The volume for a file has been externally altered so that the opened file is no longer valid.
The build log shows the following execution flow.
4>Target "GenerateSatelliteAssemblies" in file "C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets" from project "C:\source\MyProject.csproj" (target "CreateSatelliteAssemblies" depends on it):

To me it is completely unclear what is meant by the error code AL1019. The MSDN error code listing didn't help either.
