I create a new PCL project, select Store app + Phone 8 + .Net 4.5
Then, from pakage manager console, I do:
Install-Package Portable.MvvmLightLibs -Pre
but it is not installed, I get an error. What I am doing wrong?
Thank you
The error message is:
Install-Package : Could not install package 'Portable.MvvmLightLibs 4.1.24-beta3'. You are trying to install this package into a project that
targets '.NETPortable,Version=v4.5,Profile=Profile78', but the package does not contain any assembly references that are compatible with that
framework. For more information, contact the package author.

I had the same problem, but upgrading NuGet (currently 2.2) seems to have done the trick.

I have added the reference to my project.csproj file as indicated on S.O. and in the ms docs tutorial:
<ItemGroup>
<DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.1" />
</ItemGroup>
running dotnet restore claims to succeed. But the dotnet aspnet-codegenerator command can't be found and in the manage nuget packages, the CodeGeneration.Tools isn't installed and manually installing gives the error:
Package restore failed. Rolling back package changes for 'ContosoUniversity'.
This appears to be from a version compatibility issue that I don't understand or know how to fix. I have installed in my dependencies Microsoft.NETCore.App 2.0.3
and Microsoft.NETCore.APP 2.0.3 and everything else is 2.0.1. (CodeGeneration.Design, CodeGeneration.Utils etc... and running at Package Management Console Install-Package Microsoft.VisualStudio.Web.CodeGeneration.Tools Throws the error:

Downgrading everything to 2.0.0 allows me to install CodeGeneration.Tools in Nuget but I still get the error: dotnet : No executable found matching command "dotnet-aspnet-codegenerator"
Go to "Manage Nuget Package for solution" in Nuget Package Manager and
In Package Source
.
Add below detail:
Name
"nuget.org"
source
"https://api.nuget.org/v3/index.json"
If this happens, the solution to the error is to run the command at the dos command prompt in the project folder directory instead of in Package manager console. Then you can scaffold your pages without the error until MS fixes this bug.

I'm trying to install MVC 6 beta in a regular .NET 4.5.2 web project (not DNX). It gives me an error. Is this possible? Or will it eventually be supported?

I'm trying to update my project from MVC 4.0 to 5.2. But As soon I do that I get an error message:

How can I Solve this issue? And What does this mean?

What gives?
The major change to happen to ServiceStack.Interfaces is that it's now a portable library as of v4.0.30 supporting most supported platforms (Profile136):
.NET 4.0+
Xamarin.iOS
Xamarin.Android
Windows Store
Silverlight 5
If NuGet is reporting that it can't find the necessary assembly references for a supported platform than it's likely that you're using an older version of NuGet that doesn't include PCL support, which can be resolved by upgrading to the latest NuGet.
The "upgrade Nuget" option was not working for me. Turns out that versions of ServiceStack do have .NET limits. Our application is .NET 4.0, so ServiceStack.Interfaces 4.062 was the highest version we could install.
I am having an issue with the Elasticsearch.Net Nuget package.
I am not very familiar with the .Net environment and more with development, and after i followed the quick start for Nest (http://nest.azurewebsites.net/elasticsearch-net/quick-start.html) i cannot install the Elasticsearch.Net package but the Nest Nuget is installed.
The error i am getting is:
Install-Package : Unable to find package 'Elasticsearch.Net'.

Even though the documentation has been updated, the initial release of the Elasticsearch.Net 1.0 client has not been published on NuGet yet. NEST is available on NuGet as you found, but is still at version 0.12.0. Version 1.0 of Elasticsearch.Net and NEST should be released shortly. In the meantime, you can continue to use NEST 0.12.0. The 1.0 documentation is still pretty accurate for most of the basic operations and querying. Alternately, you could get the latest source for Elasticsearch.Net and NEST from the Elasticsearch.Net GitHub site, compile it locally and manually reference it your project.
