Ref assemblies in the package are broken

[smaillet]

The ref assemblies included in the ref folder of the package don't seem to work together correctly. (Version mismatches) In particular when building a task that uses Linq to XML I get the following warnings and errors:

Warning CS1701  Assuming assembly reference 'System.Xml.ReaderWriter, Version=4.0.10.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' used by 'System.Xml.XDocument' matches identity 'System.Xml.ReaderWriter, Version=4.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' of 'System.Xml.ReaderWriter', you may need to supply runtime policy

So the version of System.Xml.Document has a reference to a newer version of System.Xml.ReaderWriter than what is included in the package. Which leads to an error at build time:

Error   MSB4018 The "XXX" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load file or assembly 'System.IO.FileSystem, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

There's an obvious version mismatch on the assemblies that the taskfactory and msbuild are not able to resolve. (Tried builds from VS and dotnet.exe so it isn't dependent on the runtime used for MSBuild)

Can you please share what your inline task looks like?

It's a pretty simple task to read an XML file containing build version information

@smaillet Did you have a chance to try the new package to verify its fixed now?
