Cannot create a sub project when using the Diagnostics solution template

Question

I installed

• Visual Studio 2015 RC
• Visual Studio 2015 RC SDK
• .NET Compiler Platform SDK Templates
• .NET Compiler Platform Syntax Visualizer

However when I now try to create a "Diagnostic with Code Fix" I receive this error:

A problem was encountered creating the sub project. The imported project " C:\\Program Files (x86)\\MSBuild\\Microsoft\\Portable\\v4.5.2\\Microsoft.Portable.CSharp.targets " was not found.

Afterwards I receive two more error messages which seem to stem from this. These error messages occur as VS is trying to create the other projects in the solution template.

When I look at the folder in question, I see this structure:

I copied the contents of v4.6 and put it in a folder named v4.5.2 which indeed resolved the problem when creating the projects, but this causes build errors: System.Runtime isn't added to the projects and manually adding it causes Visual Studio to crash and the projects to become invalid.

I already repaired the entire installation, which didn't make a difference. Visual Studio 2013 runs alongside 2015.

I assume I must be missing a vital component but I can't find any indication as to what that might be. Any suggestions?

Answer 1

在创建项目之前，请尝试将新项目对话框顶部的目标框架版本更改为4.5。

Answer 2

You say you are using these templates

• .NET Compiler Platform SDK Templates
• .NET Compiler Platform Syntax Visualize

Are they the RC templates

Or the Preview templates from November?

I ask because there was a bug that caused you to reference the wrong portable targets in the Preview templates, but that should be fixed for RC.
