    Installing Umbraco 8 using nuget?

    Hi there,

    Using Visual Studio 2017

    Im trying to install Umbraco V8 using nuget without much luck. Ive tried using Web application project and just website (not application).

    After doing install-package umbracoCms, I run the project and the message goes:

    Could not load file or assembly 'Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=2.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

    Installing this and rerunning project gives me:

    Could not load type 'Umbraco.Web.UmbracoApplication'.

    Visual Code

    Using the god ole unzip works fine but has anyone succeded in installing V8 using nuget here?

    best

    Jesper

    Hi Jesper

    Please, check your Visual Studio version, it should be at least 2017 version 15.9.6+, check requirements:

    Local Development
Microsoft Windows 7 SP1
Visual Studio Code with the IISExpress extension or Microsoft Visual Studio 2017 version 15.9.6+
ASP.NET 4.7.2

    Thanks,

    Alex

    Same issue here, however I have just updated to 15.9.7

    Could not load file or assembly 'Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=2.0.1.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

    Installed using

    However...

    Could not load type 'Umbraco.Web.UmbracoApplication'.

    I had the same problem with DotNetCompiler. According to the NuGet package manager I was using version 2.0.0. Upgrading to 2.0.1 fixed this.

    Got it!

    Make sure you are installing it in a project using the correct .net framework, I hadnt updated to the latest version, so tried installing it in a 4.6.2 project (latest I had) and thats why.

    Updated to 4.7.2 and im in.

    FYI: I've update the v8-specific install guide to mention not to forget the .NET Framework version and the correct VS2017 version.

    Adding the package worked for me.

    Install-Package Microsoft.CodeDom.Providers.DotNetCompilerPlatform

    Thanks for the help.
