1) Install-Package EntityFramework
2) Add the below line in cs Projects
<ItemGroup>
    <Reference Include="netstandard" />
  </ItemGroup>
3) install netstandard from Nuget.
4)install this using package manager console 

Install-Package NETStandard.Library.NETFramework -Version 2.0.0-preview1-25305-02 -Pre
Install-Package NETStandard.Library.NETFramework -Version 2.0.0-preview2-25405-01 -Pre

5) Select the 'Web' project as the startup project.
6) Open the Package Manager Console, select the 'EntityFramework' project as the Default project and run EntityFramework's 'Update-Database' command. This will create the database. You can then change the connection string in the web.config.
7) Run the application. The default user name is 'admin' and the password is '123qwe'.

ASP.NET Boilerplate template project build error

After created and downloaded your project, you still need to follow the below steps to run your application:

  • Open your solution in Visual Studio 2017 v15.3.5+ and build the solution.

  • Select the 'Web.Host' project as the startup project.

  • Check the connection string in the appsettings.json file of the Web.Host - project, change it if you need to.
  • Open the Package Manager Console and run an Update-Database command to create your database (ensure that the Default project is selected as .EntityFrameworkCore in the Package Manager Console window).
  • Run the application. It will show swagger-ui if it is successful.

Note:If you have problems with running the application, close and then re-open Visual Studio again. It sometimes fails on the first package restore.

There are also have some requirements you have to prepare before you run this app:

  • nodejs 6.9+ with npm 3.10+
  • Typescript 2.0+

Then restore the npm packages:

npm install

For some more details info, please check the Documents for Startup Template Angular.

  3. nodejs 6.9+ with npm 3.10+
  4. gulp (must be installed globally)
  5. yarn
