Could you please help me on this.
Did I missed something?

C# VSTO Office add-in: “FindRibbons” task failed unexpectedly

Every time I compile the project, I get this error. My AssemblyInfo.cs file does not have the attributes ExcelLocale1033 or SecurityTransparent. There is no VisualStudio folder in C:\Program Files (x86)\MSBuild\Microsoft.
The "FindRibbons" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load file or assembly 'ProjectName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies.

Fixed. It's because of a new project that I added to the VSTO solution. This other project's output type (right click project > Properties) used to be Windows Application. I changed that to Class Library and deleted Program.cs which contained this code:
class Program
{
static void Main(string[] args)
{
}
}
The error never showed up again.

Could not load file or assembly 'Telerik.Reporting' on IIS without any references in the project to it

I have a web site on IIS. There are a lot of virtual folders with separates sites on it.
I`ve updated one of them and got "Could not load file or assembly 'Telerik.Reporting, Version=6.2.13.110, Culture=neutral, PublicKeyToken=a9d7983dfcc261be' or one of its dependencies. The system cannot find the file specified."
The same errors on the other virtual folder`s sites.

But in this project I don`t use Telerik at all. I created new site on IIS, deploy this project and one work well. But in the main one I still get the error.
What should I do to remove this issue from site with virtual folders? I have to deploy this project to it. I can`t delete it and create new one.
Any suggestions? Restart doesn`t help.

There could be other Web.configs that reference the telerik assembly. You would need to check all of them

nhibernate giving mysql errors - but still working fine

any idea why I am getting this in my logs on startup?

but it works perfectly fine. I am using FluentNhibernate to config my app

NHibernate uses DBProviderFactories as a fall back if loaing using reflection does not work. it could be that it logs the failing attempt even when it is able to load it.

How to fully trust a non-signed assembly?

I've got an assembly, which works just fine on my own pc, but when I try to reference it on a virtual machine, I'm getting following error:
System.IO.FileNotFoundException: Could not load file or assembly 'X.dll' or one of its ependencies. The specified module could not be found.
File name: 'X.dll'

at System.Reflection.Assembly.LoadFrom(String assemblyFile)
at kernelLoader.Program.Main(String[] args)
I'm absolutely sure that the file is at the location specified, and the code works fine on my own machine (where it has been developed). It, together with all referenced assemblies, are compiled for x86 platform.
I think, that the error may be caused by the assembly not being fully trusted.
I can't strong sing the assembly, because it references several assemblies, which are not singed, and to which I don't have the code or the rights to modify.
I suspect that there is a good way of making an assembly trusted on the mashine where I run it.
How do I mark an assembly as trusted so it can be loaded and executed?

That exception is usually caused by a missing dll. One thing that can be used is ProcMon. When the missing dll is loaded and an error is through, the file name should show up in ProcMon.
