Given that practically everyone out there (even your competitors) already uses NuGet I think it's about time we get a NuGet package added to the official NuGet package repository to ease setting up and deployment.
Note that this is not a duplicate of S36966, which is about scaffolding (even though the title says NuGet for some reason).
We have discussed this request with our R&D team and decided to decline this suggestion since at present we do not see the possibility for us to publish our products in NuGet.
It is reasonable to deliver something free and Open Source as NuGet packages. However, our .NET products are delivered as parts of our unified DXperience installer and require registration. We do not offer a possibility to install DXperience with the source code in a Trial Mode either.
In any case, we appreciate your valuable feedback and are always open to your suggestions.
Updated by Serge (DevExpress Support):
We now provide NuGet packages for our DevExtreme products (see https://www.nuget.org/packages?q=DevExtreme+). At the same time, we are still committed to our own installer for .NET and VCL products.
