Build conflict with SqlDbType

See original GitHub issue

A thread was started on an old EF Core issue that evolved into something which may be an issue with M.D.SqlClient, or should probably at least be investigated.

See https://github.com/aspnet/EntityFrameworkCore/issues/7820

Snippet of build output:

1>Build FAILED.

Confirmed that adding a newer reference fixes the issue:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.0</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Data.SqlClient" Version="1.0.19189.1-Preview" />
    <PackageReference Include="Microsoft.ApplicationInsights.AspNetCore" Version="2.8.0-beta1" />
    <PackageReference Include="System.Data.SqlClient" Version="4.6.1" />
  </ItemGroup>

</Project>

I think Wraith2’s suggestion may work around it (add a newer reference yourself). But you probably need to file an issue in the Application Insights server repo and ask them to update the version they depend on since that old System.Data.SqlClient version is where the issue lies: https://github.com/microsoft/ApplicationInsights-dotnet-server/issues
