New Post: Physical path for IIS Web Service too long

That has to be a result of your entire source code folder structure being too deep. This is just a side effect of that because to build the MSI the files are copied under obj\Debug/Release\redist, so in addition to the existing structure of your source code, it's also trying to create obj\Release\redist\ESB.AccountsReceivable.Application.Publish.Adjustment and that's pushing it over the limit.

You'll have to reduce the length of your folder names or move the entire solution to a less-nested location in your source code tree.

Thanks,
Tom
