Unable to find manifest signing certificate in the certificate store

Unchecking the "Signing the ClientOnce Manifest" doesn't always work. The solution is to remove the following lines from your csproj files

<PropertyGroup> <ManifestCertificateThumbprint>4FCE3F0998F4B89946A9D0346838E77A0C5C5568</ManifestCertificateThumbprint> </PropertyGroup> <PropertyGroup> <GenerateManifests>true</GenerateManifests> </PropertyGroup> <PropertyGroup> <SignManifests>false</SignManifests> </PropertyGroup>

The problem for me was that the checkbox "Signing the ClickOnce manifest" was checked. If you are not using signing uncheck it in Project Properties->signing->sign the clickonce manifests
