Hello,
A popular project baaaaaaaasically needs us to upgrade to Microsoft.Data.SqlClient 5.0.0. It appears that also requires me to update to SMO 170+.

I cannot get it to connect, however. My project compiles but I keep running into the following problem:

New-Object -TypeName Microsoft.SqlServer.Management.Smo.Server
New-Object : Exception calling ".ctor" with "0" argument(s): "Could not load file or assembly
'System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its
dependencies. The system cannot find the file specified."

    + CategoryInfo          : InvalidOperation: (:) [New-Object], MethodInvocationException
    + FullyQualifiedErrorId : ConstructorInvokedThrowException,Microsoft.PowerShell.Commands.NewObjectCommand

My dependencies look like this

 <ItemGroup>
    <PackageReference Include="Microsoft.Data.SqlClient" Version="5.0.1" />
    <PackageReference Include="Microsoft.Management.Infrastructure" Version="2.0.0" />
    <PackageReference Include="Microsoft.SqlServer.SqlManagementObjects" Version="170.7.0-preview" />

  </ItemGroup>

And my build script looks like this

Even if I don't load DAC it does't work (I try random stuff bc I don't understand DLLs). I've tried the suggestions around the Internet but none work. I can list them if you like but maybe you'll see a glaring problem in my build process.

Thanks,

I can only assume some other package has a conflicting dependency on System.Runtime.CompilerServices.Unsafe.

SMO 170 depends on version 5, which you can see in the nuspec

.NETFramework 4.6.2
[Azure.Core](https://www.nuget.org/packages/Azure.Core/) (>= 1.24.0)
[Azure.Identity](https://www.nuget.org/packages/Azure.Identity/) (>= 1.6.0)
[Microsoft.Data.SqlClient](https://www.nuget.org/packages/Microsoft.Data.SqlClient/) (>= 5.0.0)
[Microsoft.Identity.Client](https://www.nuget.org/packages/Microsoft.Identity.Client/) (>= 4.45.0)
[Microsoft.SqlServer.Assessment](https://www.nuget.org/packages/Microsoft.SqlServer.Assessment/) (>= 1.0.305)
[NewtonSoft.Json](https://www.nuget.org/packages/NewtonSoft.Json/) (>= 13.0.1)
[System.Buffers](https://www.nuget.org/packages/System.Buffers/) (>= 4.5.1)
[System.Diagnostics.DiagnosticSource](https://www.nuget.org/packages/System.Diagnostics.DiagnosticSource/) (>= 5.0.0)
[System.Memory](https://www.nuget.org/packages/System.Memory/) (>= 4.5.4)
[System.Runtime.CompilerServices.Unsafe](https://www.nuget.org/packages/System.Runtime.CompilerServices.Unsafe/) (>= 5.0.0)
[System.ValueTuple](https://www.nuget.org/packages/System.ValueTuple/) (>= 4.5.0)

Something else in your stack is depending on version 4 which isn't available. To make this work in NetFx, there has to be a binding redirect of some kind in place, whether it's through creation of a .dll.config file based on an app.config file generated by msbuild or by creating an AssemblyResolve function at runtime. You might also avoid it by adding a forced module load in your PS module startup.

I guess the conflict is within SMO's dependencies, most of which stem from the Azure dependencies introduced by Microsoft.Data.SqlClient.

SMO references Azure.Identity 1.6 which references System.Memory 4.5.4 which references System.Runtime.CompilerServices.Unsafe 4.5.3

Meanwhile SMO also references System.Diagnostics.DiagnosticSource 5.0 which references System.Runtime.CompilerServices.Unsafe 5.0

Maybe the right fix is to generate .dll.config files for the SMO dlls to include in the nupkg. I'll poke at that option today.

fantastic, I'll put my project on hold as I am very bad at DLLs. if you do get a dll.config working but don't want to publish a new nuget just yet, can you attach them here and I'll manually include them in my project? 🙇🏼

Here's one potential config file I hacked the SMO build to create.
Note that you probably still have to do some work in your script to get powershell to use it. See https://stackoverflow.com/questions/16216736/loading-app-config-into-the-appdomain

this should work -- a similar approach has worked in the past but first attempts do not. thank you for this, i'll keep hacking at it.

I tried for hours with the app.config and just when i was about to lose hope, I got it working thanks to this post

$redir = [reflection.assembly]::LoadFrom("C:\github\dbatools-library\bin\net462\publish\System.Runtime.CompilerServices.Unsafe.dll")

$OnAssemblyResolve = [System.ResolveEventHandler] {
    param($sender, $e)
    if ($e.Name -eq "System.Runtime.CompilerServices.Unsafe, Version=4.0.4.1, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a") { return $redir }

    foreach ($a in [System.AppDomain]::CurrentDomain.GetAssemblies()) {
        if ($a.FullName -eq $e.Name) {
            return $a
        }
    }
    return $null
}

[System.AppDomain]::CurrentDomain.add_AssemblyResolve($OnAssemblyResolve)

thx for the update. I will include a .dll.config file in future nupkg so it can at least be a reference point for dependency analysis.

Can you help me figure this out? Given the current different versions, is it possible to even get this to work?

  • To get to Microsoft.Data.SqlClient 5.0, I have to I have to find a version of SMO that supports it
  • Sweet! The newest prerelease of SMO does. I ❤️ a prerelease if all of our tests pass.
  • So I update to SMO 170.7.0-preview which depends on Microsoft.Data.SqlClient 5.0 and works on .NET 6.0.
  • Awesome, I can update the whole library to net6.0 on the Core side

I always start with 5.1 so I get that working (it was hell and I had to do some crazy stuff I never had to do before) and I move on to Core.

Everything compiles just fine and works on full framework, but when I go to connect to SQL Server on Core, I get Microsoft.Data.SqlClient platform not supported. What? So then I look at the nuget page and it says Microsoft.Data.SqlClient works on netcoreapp3.1 and doesn't list net6.0 as supported. I do not understand how SMO depend on something that can't run on that version of .net.

Is this from PowerShell - wonder if this is related? https://www.compositional-it.com/news-blog/creating-f-scripts-for-sql-data-access-on-windows-net-core-3/

@ErikEJ @potatoqualitee Yes I think the module would also need to force use of managed SNI per that article.
see https://learn.microsoft.com/sql/connect/ado-net/appcontext-switches?view=sql-server-ver16#enabling-managed-networking-on-windows

BTW any DLL that has a compile-time target of netcoreapp3.1 is runtime compatible with Net6.

Thank you both so much. I eventually figured it out with the help of comments on one of my old issues 😅

You all gave me the keywords to find some GH issues that helped:
