1. Reinstall Visual Studio 2. If it's not working, reinstall the .NET Framework.

From C# 4.0, variant types are instead mapped to dynamic (if Embed Interop Types is enabled; more on this soon), allowing you to replace the last two lines with this: excel.Cells [1, 1].Font.FontStyle = "Bold"; The disadvantage of working in this way is that you lose auto-completion, so you must know that a property called Font happens to exist. For this reason, it’s usually easier to dynamically assign the result to its known interop type: Excel.Range range = excel.Cells [1, 1]; range.Font.FontStyle = "Bold"; As you can see, this saves only five characters over the old-fashioned approach!
