I try to build a project that was developed with Visual Studio 2010, but I am using Visual Studio 2012. If I build it twice, it works without errors.

How can I fix that?

I have found Bin Deploying ASP.NET MVC 3 and _bin_deployableAssemblies and MSBuild, but I could not manage to fix those errors. Could somebody please explain step by step what I should do? I am new to C# and Visual Studio.

I think this error is also the problem why I can't Check in the project into a TFS.

I have these assemblies in my bin folder:

Answer 1

If you are bin deploying MVC 3, there are some assemblies that you have to package up in your deployment. Scott Hanselman has a good write up on what and where as well.

If you have copied the assemblies, make user to add then as 'content' to your Visual Studio project. Then they will be automatically copied into the correct structure in the bin directory when you build.

EDIT: This was the information in the article that helped solve the problem:

C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies and

C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v2.0\Assemblies contained the missing dlls

Those dlls had to be copied manually to _bin_deployableAssemblies of my project.
