We have a WebApplication build on top of .NET Core Webproject template, which targets full .NET framework version instead of .NET Core. Some of you may ask why somebody would do that. The reason is simple. There are libraries out there, which currently runs on .NET Framework only. For example IotHub Service SDK.
Because of this, we had to fallback to .NET Framework.
Usually, you should be able to do this in VS property page:
Unfortinatelly, if your project is set to .NET framework, you will not be able to do this by using VS. In that case open project file .csproj and do following changes manually (se yellow lines).
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>net461</TargetFramework>
<RuntimeIdentifier>win7-x64</RuntimeIdentifier>
<PackageTargetFallback Condition=" '$(TargetFramework)' == 'netcoreapp1.0' ">$(PackageTargetFallback);dnxcore50</PackageTargetFallback>
<PackageTargetFallback Condition=" '$(TargetFramework)' == 'net461' ">$(PackageTargetFallback)</PackageTargetFallback>
<PreserveCompilationContext>true</PreserveCompilationContext>
</PropertyGroup>
After that you will most likely get following errors:
C:\Program Files\dotnet\sdk\1.0.0-preview4-004233\NuGet.targets(70,5): error : Package Microsoft.NETCore.App 1.0.1 is not compatible with net461 (.NETFramework,Version=v4.6.1).

Please notice there NETCore.App package. This package is usually consisted part of .NET Core web application. You will have to remove it to avoid errors.
Navigate to ItemGroup (in .csproj) with package references, lookup Microsoft.NETCore.App *.* and remove it.
Following shows (as an example) how this group should look like.
<ItemGroup>
<PackageReference Include="Microsoft.AspNetCore.Authentication" Version="1.1.0" />
<PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="1.1.0" />
<PackageReference Include="Microsoft.AspNetCore.Diagnostics" Version="1.1.0" />
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="1.0.1" />
