Error "The OutputPath property is not set for project" VS 2015

Question

I have multiple projects in visual studio 2015. I am running my project in "ANY CPU" in debug mode. when I am trying to Run my project, I get the following error:

The OutputPath property is not set for project '.csproj'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='x64'.
This error may also appear if some other project is trying to follow a project-to-project reference to this project, this project has been unloaded or is not included in the solution, and the referencing project does not build using the same or an equivalent Configuration or Platform. C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.Common.CurrentVersion.targets

Answer 1

I just update the all the project solution into x64 then solution building fine.

Answer 2

For me, the problem was in the package

Microsoft.VisualStudio.Azure.Fabric.MSBuild.1.4.0

Nuget only fetched 'Microsoft.VisualStudio.Azure.Fabric.MSBuild.1.4.0.nupkg' and didnt add the folders 'build', and 'tools'. And therefore didn't have 'Microsoft.VisualStudio.Azure.Fabric.Application.props'.

Once added from an backup (didnt help restoring), I just rebuilt the project and it worked like a charm!

Wasn't the most obvious error-message.

Hope this helps someone.

May by you mean "ANY CPU" is the solution configuration? Enter to "Build\Configuration Manager" and check "Configuration" and "Platform" for you '.csproj'. Also try to check "<OutputPath></OutputPath>" in all of you cs project files. Also look which platform will be set if $(Platform) is null:

<Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>
<Platform Condition=" '$(Platform)' == '' ">AnyCPU(may be x64 here)</Platform>
