Adding Blazored.Modal package to project causes Microsoft.AspNetCore.Components.Analyzer to be loaded twice

This appears to be down to the Sdk.props file at C:\Program Files\dotnet\sdk\3.1.101\Sdks\Microsoft.NET.Sdk.Web\Sdk pulling the code analyzer into the project but it also coming in via the dependencies within Blazored.Modal.

If <TreatWarningsAsErrors>true</TreatWarningsAsErrors> is set then this causes a build issue. We can <NoWarn>8034</NoWarn> to prevent the build issues, but I figured I’d bring it to your attention just in case you need to patch something your end.

Steps to reproduce:

1. dotnet new blazorserver -n Example
2. cd Example
3. dotnet add package Blazored.Modal
4. dotnet build

Already propagated and looks good to me. Thanks for the amazingly rapid response.

I’ve just updated the package, it seems I’d updated to 3.1.100 but not 3.1.101. It’s just been pushed to NuGet and should be available in the next half hour. Let me know if you’re still seeing an issue after the update.
