安装Visual Studio 2015社区版后的几个问题

Question

I installed Visual Studio 2015 Community edition to checkout the different feature. Before that I was using VS 2013 for development. Few issues that I am facing after installing VS 2015 are

1) Package manager is not able to download few of the assemblies like Microsoft.Data.OData,Microsoft.Data.Edm

2) Solution which was building successfully in VS 2013 now gives a alert saying symbol not loaded for a particular project. No such alerts in VS2015.

I am not 100% sure these are related to VS 2015 but there are no other changes done which explains these issues.

Let me know if anyone else is also facing these issues or knows solution.

Answer 1

Didn't find the answer, so posting because this question shows in search results; comment from prashant is correct (in my case)

In my situation, we use a Git repo, all working fine on one laptop. I cloned to another laptop and I was getting this error on build, same version of VS 2015.

Reinstalling the nuget packages from the Package Manager Console worked

Update-Package -reinstall

As detailed here https://docs.microsoft.com/en-gb/nuget/consume-packages/reinstalling-and-updating-packages

edit: incidentally the issue seems to have arisen from someone changing the target framework for the projects, but not checking in the changes to the nuget packages/configs which were still targeting 4.5.2
