Unable to find manifest signing certificate in the certificate store.

Question

Problem :

I am unable to build my projects as I am facing below message:

“Unable to find manifest signing certificate in the certificate store”.

I have tried to run my Visual Studio as the Administrator and also I have tried to manually add my keys to the Windows Certificate Store. I have already tried to add the new key via a Signing tab in my Project Properties but above error is still appearing.

I am unable to fix above error. Can someone guide me in fixing above error?

Answer 1

I had faced the above error in the past and after doing lot of trials I found the solution on it

I am sharing my solution as below hope this will help someone else too.

So you need to edit your .csproj file for your project which is facing above error.

It is very simple you just need to delete the below lines of code:

<PropertyGroup>
   <ManifestCertificateThumbprint>...........</ManifestCertificateThumbprint>
</PropertyGroup>
<PropertyGroup>
   <ManifestKeyFile>xxxxxxxx.pfx</ManifestKeyFile>
</PropertyGroup>
<PropertyGroup>
   <GenerateManifests>true</GenerateManifests>
</PropertyGroup>
<PropertyGroup>
   <SignManifests>false</SignManifests>
</PropertyGroup>

If above approach is not working for you then you should try below steps as solution.

Go to your Solution Explorer:

You need to right click on your project

Then you can click on properties

You can find it usually on your left-hand side then you can select the "Signing" tab

After that you must check off your Sign the ClickOnce manifests

Finally you must make sure you to save! the changes you have just made.
