DacFx doesn't work on .NET 6

• SqlPackage or DacFx Version: 150.5164.1
• .NET Framework (Windows-only) or .NET Core: .NET 6
• Environment (local platform and source/target platforms): macOS, Linux

Hi there, I’m the maintainer of MSBuild.Sdk.SqlProj and we’ve been working on upgrading that project to make it compatible with .NET 6. Unfortunately we’ve ran into an issue in DACFX where it seems that it is depending on Strong-name signing which seems to be no longer supported on .NET 6. We are seeing the following stack trace:

System.PlatformNotSupportedException: Strong-name signing is not supported on this platform.

     at Microsoft.SqlServer.Dac.Model.TSqlModel..ctor(SqlServerVersion modelTargetVersion, TSqlModelOptions modelCreationOptions)

Steps to Reproduce:

1. Create a new Console app on .NET 6 (dotnet new console)
2. Instantiate a new TSqlModel using the constructor that takes a SqlServerVersion and TSqlModelOptions.
3. Run the app and see the above exception

Did this occur in prior versions? If not - which version(s) did it work in? It works fine on .NET 5.

@jmezach sorry about the delay. I have a fix for this and planning to include it in the next release of DacFx Nuget package.

Thanks for confirming the fix. We’re planning to release by end of the year.
