"The XamarinTelemetry task failed unexpectedly" on second build-CodePudding

With the latest VS preview (VS 17.3 Preview 3), with both Android and iOS, building my application works the first time I build it, but the second time it fails with

The "XamarinTelemetry" task failed unexpectedly.

Looking at the logs I see this:

The only workaround I've found is to clean the entire solution and rebuild, which succeeds, but then fails again the next time I try to build.

Has anyone found a solution to this?

CodePudding user response：

I'm not sure why Newtonsoft.Json 13 is mentioned in the debug output, but I did have Newtonsoft.Json 12.0.1 installed, which is deprecated in NuGet due to a high severity security issue.

Updating to the latest Newtonsoft.Json fixed the issue. I have no idea why that leads to such weird symptoms.

For anyone who runs into the same issue but with a different NuGet package, the debug output mentioned above can be found under View --> Output --> Show output from "Build"

CodePudding user response：

There are several config files in the VS installation which reference 13.0.0.0

<bindingRedirect oldVersion="0.0.0.0-13.0.0.0" newVersion="13.0.0.0" />

I replaced these with

<bindingRedirect oldVersion="0.0.0.0-13.0.1.0" newVersion="13.0.1.0" />

and was able to build. It seems that the 13.0.0.0 is not publicly available as nuget package...
