编译和发布失败 .Net Core

Question

I have setup two machines to compile and publish a .netcore web application.

One seems to work OK, the other does not.

The problem machine claims to have succeeded with the build, but the publish fails because no DLL was produced.

The build/publish output is as follows, I would be very grateful on where I go from here to track down what is wrong

1>------ Build started: Project: Engine, Configuration: Release Any CPU ------
1>  C:\Program Files\dotnet\dotnet.exe build "C:\Users\Dev\Documents\Visual Studio 2015\Projects\Engine\src\Engine" --configuration Release --no-dependencies
1>  Project Engine (.NETCoreApp,Version=v1.0) will be compiled because expected outputs are missing
1>  Compiling Engine for .NETCoreApp,Version=v1.0
1>  Compilation succeeded

2>Publish failed due to build errors. Check the error list for more details.

Machine is Windows 10 Pro, all updates installed. IDE is Visual Studio Enterprise 2015, Version 14.0.25431.01 Update 3 Using .NetCore SDK version 1.0.0-preview2-003131

Answer 1

It is odd that the compiler claims the binary was built but yet the Publishing process claims it was not there.

By monitoring the build directory contents at compile time it became obvious that the DLL was being built, but then was immediately deleted.

A quick check of the Norton/Symantec virus checker running on this machine, showed that it was responsible for eating the DLLs.

There was nothing wrong with the development environment itself.

I added the project tree to the exclusion list for the virus checker and it all works fine now.
