Patches

If you’re using YARP 1.0.0, you should update to NuGet package version 1.0.1.
If you’re using YARP 1.1.0-RC.1, you should update to NuGet package version 1.1.0-rc.1.22211.2.

You can do so by updating the PackageReference in your .csproj file

&lt;ItemGroup&gt;
- &lt;PackageReference Include="Yarp.ReverseProxy" Version="1.0.0" /&gt;
- &lt;PackageReference Include="Yarp.Telemetry.Consumption" Version="1.0.0" /&gt;
+ &lt;PackageReference Include="Yarp.ReverseProxy" Version="1.0.1" /&gt;
+ &lt;PackageReference Include="Yarp.Telemetry.Consumption" Version="1.0.1" /&gt;
&lt;/ItemGroup&gt;

or by selecting 1.0.1 in the NuGet UI inside Visual Studio (Manage NuGet Packages / Updates)
