Aspnetcore: dotnet restore fails after getting version 1

Created on 27 Jun 2016  路  19Comments  路  Source: dotnet/aspnetcore

This issue popped up this morning after the Microsoft.NETCore.App (>= 1.0.0) was upgraded to version 1 from RC2. The problem occurs when I run a dotnet restore as a VSTS build step as well as locally on my VS2015 box.

Steps to reproduce

run dotnet restore on a MVC website

Expected behavior

dotnet restore works

Actual behavior

Errors in S:\portal\src\portal.Web\Portal.Web.xproj

I have resolved the build issue, though not sure if this is the right fix. I changed this line:

"Microsoft.NETCore.App": "1.0.0",

to this:

"Microsoft.NETCore.App": {
      "version": "1.0.0",
      "type": "platform"
    },

Try updating your tools to preview2

BrennanConroy picture BrennanConroy on 27 Jun 2016

updating SDK tools and VS 2015 tools to preview 2 seems to not resolve the issue.

jsouthron picture jsouthron on 27 Jun 2016

Update your dotnet to preview 2 also

BrennanConroy picture BrennanConroy on 27 Jun 2016

Yes I did both. I removed all dotnet from add/remove programs and installed the following two:

DotNetCore.1.0.0-SDK.Preview2-x64.exe
DotNetCore.1.0.0-VS2015Tools.Preview2.exe

I obtained both installers from here -> https://www.microsoft.com/net/core#windows

jsouthron picture jsouthron on 27 Jun 2016

Umm, okay... when I said tools I also meant this stuff 

"Microsoft.AspNetCore.Razor.Tools": {
      "version": "1.0.0-preview1-final",
      "imports": "portable-net45+win8+dnxcore50"
    },

This seems to resolve the dotnet restore issues, however now I get compile issues:

1>C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\DotNet\Microsoft.DotNet.Common.Targets(262,5): error : Can not find runtime target for framework '.NETCoreApp,Version=v1.0' compatible with one of the target runtimes: 'win10-x64, win81-x64, win8-x64, win7-x64'. Possible causes:

@jsouthron - not that this is causing the issue you are seeing but your references to tools seem to be misplaced. Some tools do need to be called out in application dependencies but tools that don't need to load/compile your project need to be only in the tools section. You can use this announcement to see what tools should go where. Razor tools (not there) should go in both "dependencies" and "tools" (similar to EF tools). Also, I believe you no longer need "imports".

moozzyk picture moozzyk on 27 Jun 2016

@moozzyk - I had the same thoughts as you did. I updated the tools through Nuget Package Manager and that is how they ended up looking in project.json. I thought they didn't quite look right as dependencies rather than tools, however after playing around with this for hours, and having it work, I am satisfied for now. I imagine .net team will clean a lot of this up soon.

jsouthron picture jsouthron on 27 Jun 2016

@yishaigalatzer - any thoughts on Nuget Package Manager moving tools references out? I am not sure if what is in the project after the changed made by Nuget Package Manager can even run...

moozzyk picture moozzyk on 27 Jun 2016

Tool packages must be updated by editing the project.json file directly.

This scenario isn't supported in the NuGet UI today, and when the request to update/install is made it goes through the project system to update the project.json file.

emgarten picture emgarten on 27 Jun 2016

@moozzyk it turns out that the site can run, however you cannot run dotnet publish-iisso if you are trying to substitute the web.config correctly (i.e., run the site in IIS), you will need to manually add this back in

 "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
  },
jsouthron picture jsouthron on 28 Jun 2016

Yes, you have to have:

 "tools": {
    "Microsoft.AspNetCore.Server.IISIntegration.Tools": "1.0.0-preview2-final"
  },

without this the tool won't get restored and the postpublish script will fail (note - it won't fail publish) so you will end up with a web.config file that don't have correct entries and the application will not start in IIS.

Thank You @jsouthron
I was having an error after upgrading mvc core from 1.0 to 1.0.1

Can not find runtime target for framework '.NETCoreApp,Version=v1.0' compatible with one of the target runtimes: 'win10-x64, win81-x64, win8-x64, win7-x64'

and replacing in project.json
"Microsoft.NETCore.App": "1.0.1"
to

"Microsoft.NETCore.App": {
      "version": "1.0.1",
      "type": "platform"
    }

fixed it for me

@CalvinDale don't know why i am getting this same issue today, i had worked on the same package earlier and it used to work for me......nothing has changed since than only thing is my VS2015 has expired.

its-saurabhjain picture its-saurabhjain on 1 Nov 2016

@its-saurabhjain I haven't had any luck with it. I've tried repaving all .NET Core and VS 2015 installs several times. My next step should be to repave the OS and start over. But instead I'm waiting for a new machine before I proceed.

Are the .Net Core / Angular 2 project templates fixed yet ?

Today, I've installed the latest version of .Net Core into VS2015 Update 3, and now, when I create a new project of type "ASP.Net Core Angular 2 Starter Application (.Net Core)", I get this error:

Errors in C:\Projects\DotNetCoreAngular2ApplicationTest\DotNetCoreAngular2ApplicationTest\DotNetCoreAngular2ApplicationTest.xproj
    Unable to resolve 'Microsoft.AspNetCore.AngularServices (>= 1.0.0)' for '.NETCoreApp,Version=v1.0'.

Looking at the project.json, a of of these libraries are underlined, as though they're not installed:

dotnetdependences

And if I try doing "Restore NuGet Packages" on this solution, I get a message to say:
All packages are already installed and there is nothing to restore.
... which is ironic, given what's waiting for me in the "Error List" tab...

dotnetdependences2

Errrrm.... I'm not impressed so far....

Again, all of these errors occur just by attempting to create a new Project. I haven't attempted to write one line of code yet...
