.Net Core 3.0 Console App. Microsoft.Data.SQLClient is not supported RRS feed

  • Question

  • Hi.  I just tried to publish my first .net core app (console).  I set it to self-contained and copied the output manually to the server where I got a "Microsoft.Data.SqlClient is not supported on this platform" error.  It works locally of course.  Doing a Google dive I found post build steps to make sure that the [appname].deps.json and the function.deps.json files need to be there and they are.  Inside I see 


        Microsoft.Data.SqlClient/1.0.19269.1": {
            "dependencies": {
              "Microsoft.Identity.Client": "3.0.8",
              "Microsoft.Win32.Registry": "4.7.0",
              "System.Configuration.ConfigurationManager": "4.7.0",
              "System.Runtime.Caching": "4.7.0",
              "System.Security.Principal.Windows": "4.7.0",
              "System.Text.Encoding.CodePages": "4.7.0",
              "runtime.native.System.Data.SqlClient.sni": "4.7.0"
            "runtime": {
              "runtimes/win/lib/netcoreapp2.1/Microsoft.Data.SqlClient.dll": {
                "assemblyVersion": "1.0.19269.1",
                "fileVersion": "1.0.19269.1"

    as well as further references in the file under EF

    "Microsoft.EntityFrameworkCore.SqlServer/3.1.3": {
            "dependencies": {
              "Microsoft.Data.SqlClient": "1.0.19269.1",
              "Microsoft.EntityFrameworkCore.Relational": "3.1.3"
            "runtime": {
              "lib/netstandard2.0/Microsoft.EntityFrameworkCore.SqlServer.dll": {
                "assemblyVersion": "",
                "fileVersion": "3.100.320.12804"

    and even more

     "Microsoft.Data.SqlClient/1.0.19269.1": {
          "type": "package",
          "serviceable": true,
          "sha512": "sha512-p2xa+sUAt7IRNxCl8ZT77bd7qHVKookDJ4HDUc+ArWkFk204rIpFhHajCTQqomSbcYi+olwheqQrwr+ohGRmJw==",
          "path": "microsoft.data.sqlclient/1.0.19269.1",
          "hashPath": "microsoft.data.sqlclient.1.0.19269.1.nupkg.sha512"

    Any insight would be much appreciated.  Most help seems to be in the context of adding the missing files and/or web based tech's targeted Nuget packages.  Thank you.

  • Thank you for the feedback.  I did see this post chain and I guess I am not making the connection because I am not trying to load using reflection at all.  For the purposes of this app I am not even using DI.  Thanks.

  • Maybe you need to be using Core 2.x



    The Microsoft.Data.SqlClient package supports the below environments:

    • .NET Framework 4.6+
    • .NET Core 2.1+
    • .NET Standard 2.0+.
