TemporaryGeneratedFile_[guid] in /obj/debug breaking build

Question

I have 3 temporary files being created in obj/debug:

E.g.

• TemporaryGeneratedFile_036C0B5B-1481-4323-8D20-8F5ADCB23D92.cs
• TemporaryGeneratedFil

Answer 1

The 3 files with "TemporaryGeneratedFile_" prefix are auto-generated by the Microsoft.WorkflowBuildExtensions.targets file most likely imported via the chain:

• *.csproj -->
• Microsoft.CSharp.targets -->
• Microsoft.Common.targets -->
• Microsoft.WorkflowBuildExtensions.targets

They are generated under the intermediate output path pointed by the $(IntermediateOutputPath) MSBuild property, usually something like obj\debug. One way to deal with the StyleCop warnings/errors about these auto-generated files is to tell StyleCop to skip any *.cs files under the $(IntermediateOutputPath). For example, include the following item in your project:

ExcludeFromStyleCop is an item name recognized by the StyleCop.targets file to exclude files from analysis during a build (at least for StyleCop 4.7). The double star ** is MSBuild syntax for searching recursively under a folder.

The new item might show up in the Solution Explorer in Visual Studio. If that is undesirable it can be hidden by using the 'Visible' item metadata:

    
        False
    

Similar approach can be used to exclude other files if necessary. I hope that helps.
