I have created project from aspnetboilerplate templates ASP.NET MVC 5.x, Multipage application with ef.

I have unzipped the downloaded file
I have started Visual Studio as an administrator
aspnetboilerplate site says we can use Visual Studio 2013 or later and My Visual studio version is: Microsoft Visual Studio Professional 2015 Version 14.0.25431.01 Update 3 Microsoft .NET Framework Version 4.7.02046

When I try to open and build the project, the project has build errors which I have tried to resolve by from Boilerplate project creation error but still its unable to resolve.

Build errors details are:

  1. error CS0012: The type 'Object' 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'.
  2. error CS0006: Metadata file 'D:\AAA\Projects\SourceCode\Practices\MVC\HelloWorld\3.1.3\src\HelloWorld.Application\bin\Debug\HelloWorld.Application.dll' could not be found
  3. error CS0006: Metadata file 'D:\AAA\Projects\SourceCode\Practices\MVC\HelloWorld\3.1.3\src\HelloWorld.Core\bin\Debug\HelloWorld.Core.dll' could not be found
  4. error CS0006: Metadata file 'D:\AAA\Projects\SourceCode\Practices\MVC\HelloWorld\3.1.3\src\HelloWorld.EntityFramework\bin\Debug\HelloWorld.EntityFramework.dll' could not be found
  5. error CS0006: Metadata file 'D:\AAA\Projects\SourceCode\Practices\MVC\HelloWorld\3.1.3\src\HelloWorld.WebApi\bin\Debug\HelloWorld.WebApi.dll' could not be found

I have tried all options searching for solution still its not resolving. Any suggestions/help is appreciated.

Unfortunately, that is an outdated instruction.

The type 'Object' 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'.

ABP v3.0.0 is based on .NET Standard 2.0.

  • This concerns you regardless if you are on MVC 5.x, .NET Framework 4.x or .NET Core 2.x.
  • You should use VS2017 15.3.3+.

Using VS2017 15.3.3+, the projects will build, resolving errors 2 to 5.
