Xamarin.Forms android can not resolve reference: System.Diagnostics.PerformanceCounter, referenced by StackExchange.Redis

[tomasfabian]

Hi,
I have a Xamarin.Forms.Droid build problem:

Severity Code Description Project File Line Suppression State
Error Can not resolve reference: System.Diagnostics.PerformanceCounter, referenced by StackExchange.Redis. Please add a NuGet package or assembly reference for System.Diagnostics.PerformanceCounter, or remove the reference to StackExchange.Redis. Xamarin.Sample.Android

I also tried to include System.Diagnostics.PerformanceCounter package:

    <PackageReference Include="StackExchange.Redis">
      <Version>2.1.30</Version>
    </PackageReference>
    <PackageReference Include="System.Diagnostics.PerformanceCounter">
      <Version>4.7.0</Version>
    </PackageReference>

Is it possible to use StackExchange.Redis with Xamarin.Forms apps?

Thank you, Tomas

I have the same issue. Adding NuGet package doesn't solve anything

[UPDATE]

Most probably this is correlated with nuget package reference and this bug especially: dotnet/android#2674

Going back to packages.config fix the issue (i just read it - i will right now try it;) )

Tried install both of packages in shared and droid projects. Placed packages.config with reference on PerfomanceCounter in root of droid project. Nothing worked. How to fix this issue? Does redis unusable with forms?

@mgravell Would it be possible to remove the reference to the performance counter based on @SouJack PR for MonoAndroid10 and Xamarin.iOS10 (cfr. https://docs.microsoft.com/nl-be/xamarin/cross-platform/app-fundamentals/nuget-manual) to be able to use these within Xamarin Forms and Xamarin Native projects.

[mgravell]

Is there a TFM that Xamarin and monodroid would pick up, more specific than the current TFMs? Adding a TFM is a practical option.

MonoAndroid10 and Xamarin.iOS10 are the TFM targeting Android 1.0 + and IOS 1.0+ (e.g. AzureAD also uses multi targeting to remove a certain part of the API for Android and IOS)
I hope this help.

Any update on this issue please, Is it possible to use StackExchange.Redis with Xamarin.Forms apps?

[mgravell]

I am going to look at what is involved in using those TFMs in terms of build servers etc; but no, it isn't "done" yet. Probably look Tuesday (long family weekend).

I'm also looking to use StackExchange.Redis with Xamarin.Forms app. Any update on this one please?

I'm looking at TFMs since adding net6.0 here for other reasons. I'm not sure what the landscape looks like though - if we added a build for net6.0-ios and net6.0-android...would that work for people in having a build without this dependency/functionality?

[NickCraver]

Can anyone here chime in on if such TFMs would be useful? If so we could add and conditional the reference but it adds maintenance so I'd like to see if we're actually solving a problem still :)

[NickCraver]

I'm going to close this out since there doesn't seem to be a current need. If the above new TFMs do help someone I'm wide open to adding them, but with no responses I'm reading that this isn't a current issue or at least a pressing one at not worth adding.
