4 years ago I have the same/similar issue. Running nuget.exe update with -FileConflictAction Ignore or IgnoreAll will delete any file that were including in the ~/Content folder of the nupkg package that has been changed. They will not be re-added, they are not ignored if they are changed, they are just removed. Setting the -FileConflictAction to Overwrite does overwrite them but then the user's changes are lost. My log output shows that it detects the file conflicts but these files are still removed which i think might actually happen early in the update phase when the original package version is removed.
This is using the legacy project/packaging with packages.config. The strange thing is that this operation works fine within Visual Studio. It just doesn't behave the same with nuget.exe. If anyone can tell me how to ensure the same behavior from cmd line as VS that would solve my problem. Perhaps I need to use an older version of nuget?
This is using vLatest as of last week: 5.5.1.6542
NuGet product used (NuGet.exe | VS UI | Package Manager Console | dotnet.exe): NuGet.exe
NuGet version (x.x.x.xxx): 4.5.1.4879
OS version (i.e. win10 v1607 (14393.321)): win7 SP2, win10 v1709
Worked before? If so, with which NuGet version: bug exists in 3.5.0.1996, was not able to test on earlier versions
NuGet.exe update command breaks project files in the following cases:
Detailed repro steps so we can see the same problem
Use attached project UpdateBugTestClient to reproduce, issue happens on any package with content files
Update package with the following command: nuget.exe update UpdateBugTestClient.sln -Id UpdateBugTestPackage -Version 1.1.0 -FileConflictAction Ignore
Content file UpdateBugTestPackage.dll.config is deleted, project is damaged and cannot be built
Update package with the following command: nuget.exe update UpdateBugTestClient.sln -Id UpdateBugTestPackage -Version 1.2.0
Content file UpdateBugTestPackage.dll.config is deleted as expected but reference is left in project file, project is damaged and cannot be built
Other suggested things
As far as I can see in source code of NuGet.exe, uninstall package action for command line version has incorrect implementation, it simply deletes content file on disk but does not remove the reference from project file. That is the root cause for both issues.
