I'm in the process of trying to upgrade my applications to .NET Framework 4.7.1 and I ran into the following warning when building the apps.
1>------ Rebuild All started: Project: ConsoleApp7, Configuration: Debug Any CPU ------

If you set Tools|Options|Projects and Solutions|Build and Run|MSBuild project build output verbosity to Detailed you can see that it appears that there is a conflict with System.Runtime.InteropServices.RuntimeInformation.
1> There was a conflict between "System.Runtime.InteropServices.RuntimeInformation, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" and "System.Runtime.InteropServices.RuntimeInformation, Version=4.0.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a".

Is there something that can be done with the NuGet package to eliminate this warning? I tested this by creating a .NET Framework 4.7.1 console application with nothing else in it and right after adding the latest MySqlConnector package, it gives the errors when you do a build. Also, I tried updating the dependent packages since there were updates and the problem still occurs.
The text was updated successfully, but these errors were encountered:
I can reproduce this problem with both a "traditional" CSPROJ and a new "Sdk-style" CSPROJ file. It looks like C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.7.1\Facades\System.Runtime.InteropServices.RuntimeInformation.dll is new in .NET 4.7.1 (and not present in the v4.7 folder) so I wonder if it's part of the problem.
One solution would be to remove the System.Runtime.InteropServices.RuntimeInformation dependency for the net45 and net46 builds (and only use it for netstandard). It appears that a S.R.IS.RI dependency causes problems with mono on Mac (dotnet/corefx#9012) so eliminating it could have additional benefits.
Wow! Great work! I still had the NuGet screen up in Visual Studio from this morning and it displayed that an update was available. I didn't even have to scan for updates or anything. Just clicked Update, and it appears to have worked like a charm. No more warning. I think I may be using other packages that have similar problems, but, at least this one is fixed. Thanks for the quick response. Job well done.
