Description:
When compiling a program that references MySql.Data v8.0.32, dotnet build produces a lot of MSB3246 build warnings. This did not occur with v8.0.31.

The build warnings are:

  Test -> C:\Code\MySql\Test\bin\Debug\net7.0\Test.dll

Build succeeded.

    5 Warning(s)
    0 Error(s)

How to repeat:
Install .NET SDK v7.0.102.
Run: dotnet new console
Run: dotnet add package MySql.Data
Run: dotnet build

Suggested fix:
Expected 0 warnings, 0 errors, as happened when using MySql.Data 8.0.31:

❯ dotnet build
MSBuild version 17.4.1+9a89d02ff for .NET
  Determining projects to restore...
  Restored C:\Code\MySql\Test\Test.csproj (in 291 ms).
  Test -> C:\Code\MySql\Test\bin\Debug\net7.0\Test.dll

Build succeeded.

Fixed as of the upcoming MySQL Connector/NET 8.0.32.1 NuGet-only release, and here's the proposed changelog entry from the documentation team:

An Important Update 

The Connector/NET MySql.Data version 8.0.32.1 NuGet
package now is released and the newer package supersedes the original
8.0.32 package. All of the dotnet build warnings produced when compiling a
program that references MySql.Data version 8.0.32 (and related issues) are
resolved when referencing the MySql.Data 8.0.32.1 package.

Thank you for the bug report.

@Christine Cole, I may be mistaken on what you meant by released, but I don't see that nuget package as released.

https://www.nuget.org/packages/MySql.Data/#versions-body-tab

As of today the latest version is 8.0.32, I don't see any 8.0.32.1 or 8.0.32.1 pre-release.

Can you confirm that I am looking at the right place and that it is indeed missing?
