问题
I created a Web API project using the default ASP.NET Core Web Application (.NET Framework) template and then published to local folder using VS.
Now if I call dotnet application.exe in the console, I receive the following error:
A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found
I have found in this answer and this issue on github, that the actual problem is a missing emitEntryPoint property. All is fine, except that my project.json already has "emitEntryPoint": true
What else can cause this error?
回答1:
Once you publish the application and have a .exe file, you don't need to use dotnet anymore. The application is compiled!
Just run application.exe by double-clicking it, or launching it from the console.

Make sure you install the correct version of ASP Net Core in the server.
Here is the download link:

We ran in the same problem building our app in CI. Apparantly a reference towards another unittest project slipped in. This Created the error at hand.
