Code Signing Certificates For C# and .NET Applications

Digitally sign your ClickOnce manifests, Windows Authenticode, and other Windows applications using a C#/.NET Code Signing Certificate for as little as $195 per year (save 19% off retail).

C# is the go-to programming language for many games, financial and business applications, and cloud-based apps. Releasing unsigned C# (C-Sharp) or .NET Windows applications can result in unknown publisher warnings that make users not want to install your apps.

Not sure where to find a C#/.NET code signing certificate at the best price? We’re here to help. Let’s compare Windows-trusted code signing certificate options to help you identify the right one for your software project.

Spoiler Alert: C# Code Signing Certificates Sign More Than Executables

Did you know that “C# code signing certificates” and “.NET code signing certificates” aren’t limited to signing ClickOnce manifests or C# applications only?  That’s right — they can also be used to sign other code, too. So, why do people within the industry call them C# or .NET code signing certificates?

Although it seems limiting, these certificates are commonly referred to using names that relate to their specific applications and uses. For example, you’ll see people talking about Windows Code Signing Certificates and Authenticode Signing Certificates for the same reason. But these certificates also can be used to sign a wide variety of other digital assets as well.

Yeah, the names are a bit misleading when you consider how versatile they really are. But the truth is that you can use these digital certificates to sign everything from drivers and scripts to software applications, executables, and other types of code.
