迁移到 .net core
.我已经有了 .xproj
,但是当我运行 dotnet build
时出现错误:
I am migrating a library from .Net 4.5
to .net core
. I already have the .xproj
in place, but when I run dotnet build
I get the error:
Microsoft.DotNet.Common.Targets(262,5):错误:对象引用未设置为对象的实例.

这是我的 project.json
文件:
{
"version": "1.0.0",
"frameworks": {
"net45": {
"frameworkAssemblies": {
"System.Collections.Concurrent": {
"type": "build"
}
}
},
"netstandard1.6": {
"imports": "dnxcore50",
"dependencies": {
"NETStandard.Library": "1.6.0"
}
}
}
}
有什么我遗漏的吗?
推荐答案
Running dotnet restore
from command line 工作但不是来自 Visual Studio 2015 Update 3.我怀疑这与拥有私有nuget 提要.
Running dotnet restore
from command line worked but not from Visual Studio 2015 Update 3. I suspect this has something to do with having private nuget feeds.
