I have VS.NET 10.0.40219.1 SP1 in 2 computers and when I create a new C# Winform app only do it with Properties/Build/Platform x86, and the target let me choose AnyCpu/x64, but can’t set it in the configuration (however, libraries work fine).
If I try to change it in the project file manually, I get a lot of nasty errors. Is this normal behavior, a bug or a problem in my installation?
P.D: When I change manually the project, this happend:
Warning 1 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=’x86′. 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:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets
When I reopen the project, ALL the references become invalid
It is normal for Visual Studio to create WinForms projects with just an x86 platform. I have no idea if that’s because historically x86 was the only platform type or because x86 is the most commonly used value or for some other reason.
It’s also normal to have problems when the project file is manually modified, try to avoid doing that where possible.
