Errors on installing into a netcore2.0 project

[EvilShrike]

I've tried to install Devart.Data.PostreSql v.7.9.958 from nuget.org into a netcore2.0 project (inside VS2017.3). It fails with the following error.
The same error happens for SQLite provider. I didn't tried other ones.

Code: Select all

Any ideas?

via dotnet CLI tool it can be installed but when opened in VS it produces the same errors:

Error NU1605 Detected package downgrade: System.Net.Primitives from 4.3.0 to 4.0.11. Reference the package directly from the project to select a different version.

I've tried to install Devart.Data.PostreSql v.7.9.958 from nuget.org into a netcore2.0 project (inside VS2017.3). It fails with the following error.

.NET Core 2.0 is currently not supported. We are working on the feature and will notify you when it is implemented.

.NET Core 2.0

Oh. Then please add some note onto https://www.devart.com/dotconnect/postg ... tions.html page as it states ".NET Core support". So does for all other your providers.
I wasted so much time on this..
For me ".NET Core support" means .NET Core 2.0 as well. Does it only work on 1.x?

Thank you for your suggestion.

Does it only work on 1.x?

dotConnect for PostgreSQL supports .NET Standard 1.3.

[EvilShrike]

If it supports NetStandard1.3 then it should support NetCore2.0 as well.
Actually right after the package installed build fails but adding theses packages makes it succeed:

Code: Select all

    <PackageReference Include="System.Net.Primitives" Version="4.3.0" />
    <PackageReference Include="System.Reflection" Version="4.3.0" />
    <PackageReference Include="System.Runtime.InteropServices.RuntimeInformation" Version="4.3.0" />
    <PackageReference Include="System.Security.Cryptography.Algorithms" Version="4.3.0" />
    <PackageReference Include="System.Security.Cryptography.Csp" Version="4.3.0" />

Hope you'll release a package which wouldn't require such overriding.

Do I understand correctly that currently these're no trial versions for netcore?

There is a trial period for .NET Core assemblies as well: https://www.devart.com/dotconnect/oracl ... ndard.html.

Some update.
I can confirm that with mentioned package references a project can build on netcoreapp2.0 and run (both on windows/linux).

To build and run on net462 there should be one more package added:

Code: Select all

  <ItemGroup>
    <PackageReference Include="Devart.Data.PostgreSql" Version="7.9.958" />
    <PackageReference Include="System.IO.FileSystem.Primitives" Version="4.3.0" />
    <PackageReference Include="System.Net.NameResolution" Version="4.3.0" />
    <PackageReference Include="System.Net.Primitives" Version="4.3.0" />
    <PackageReference Include="System.Reflection" Version="4.3.0" />
    <PackageReference Include="System.Runtime.InteropServices.RuntimeInformation" Version="4.3.0" />
    <PackageReference Include="System.Security.Cryptography.Algorithms" Version="4.3.0" />
    <PackageReference Include="System.Security.Cryptography.Csp" Version="4.3.0" />
  </ItemGroup>
  <ItemGroup Condition="'$(TargetFramework)' == 'net462'">
    <PackageReference Include="System.Security.Principal.Windows" Version="4.3.0" />
  </ItemGroup>

Thank you for your feedback.
