Why is a "bindingRedirect" added to the app.config file after adding the Microsoft.Bcl.Async package?
Solution 1
The assemblies Microsoft.Threading.Tasks
and Microsoft.Threading.Tasks.Extensions
are still referencing v1.5.11.0 of System.Runtime
and System.Threading.Tasks
.
Without the bindingRedirect
, the Microsoft.*
assemblies would try to load an old version of the System.*
assemblies, which would fail.
Solution 2
You are simply saying whenever there is older version that is between 0.0.0.0 to 2.5.19.0, please replace that version with the new version that is 2.5.19.0
Let's say you don't have the older version available in your project and you are trying to access it, then you will end up with an error like "System.IO.FileLoadException: 'Could not load file or assembly"
So when your project is looking for an older version of that DLL it will simply replace that with new one which is available

I was wondering why nuget added the following code to my applications
app.config
file, after installing theMicrosoft.Bcl.Async
:<runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-2.5.19.0" newVersion="2.5.19.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Threading.Tasks" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-2.5.19.0" newVersion="2.5.19.0" /> </dependentAssembly> </assemblyBinding> </runtime>
If I remove this XML-element from the config, the app will not work properly.
As far as I understand it, we can use the
bindingRedirect
to make the app load a newer or older version of an assembly in case the version we were using when compiling the EXE is gone.
However I am using exactly the version2.5.19.0
, why would I need a redirect then?Why do I need this
bindingRedirect
? -
zinking over 10 yearsI have a similar situation, where the redirected assembly is not used else where at all, but the bindingredirect is still needed? -- or can I assert that if the old version of the assembly is not referenced anywhere then the bindingredirect is not needed at all.
