Hi,
I'm trying to upgrade our solution to 4.5.1 .... but in VS 2015 I'm geting folowing error:
Error CS0012 The type 'Attribute' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.
Please help!

Hi @dmali,
Which version of VS 2017 do you use ? Is it greater than v15.3.3 ?
Your problem could be similar to <a class="postlink" href="https://github.com/dotnet/standard/issues/474">https://github.com/dotnet/standard/issues/474</a>.

Hi @dmali,
You must use VS2017 v15.3.3 or newer version.
Check this: #3982@32380b50-9ed1-4b3f-94c0-10b0bbd06a9e

Hi @alirizaadiyahsi,
thank you for your support, but we are not working with NET CORE and therefore I don't see any reason why we need to suddenly use/buy a new licenses for VS 2017.
@ismcagdas: Any idea how to get it to work in VS 2015?
Kind regards

For VS2015, you may try installing NuGet client 3.6 or higher but that may no longer work.

ABP targets .NET Standard 2.0, which supports .NET 4.6.1 Framework. Your issue is with Visual Studio tooling, which is not within our control.

Hi aaron,
that is correct, but as it look like it is working only with VS 2017 15.3 as stated also on NET Standard 2.0 announcment page:
The .NET Standard 2.0 specification is now complete. It is supported in .NET Core 2.0, in the .NET Framework 4.6.1 and later versions, and in Visual Studio 15.3. You can start using .NET Standard 2.0 today.
my problem is that i'm stuck with VS 2015 for another 6 months or so and would really like to update my solution to 4.6.0.
Is there anything you can do about this? Would it be possible to still release ABP assemblies for both "frameworks" like you did for version 2.3.0 (netstandard 1.6 and net46)?

Hi @dmali,
Sorry for the late reply. We are not planning to release ABP for netstandard 1.6 and net46, sorry.
