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.
File name: 'ProjectName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

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.

System.BadImageFormatException error

I am using Windows Server 2008 R2 Datacenter 64-bit OS. I am using Visual Studio 2013 that has a solution with 2 projects and I am encountering this error.

I have also tried changing the Enable 32-bit Applications in the IIS Application Pools to True but the System.BadImageFormatException error still persist. Greatly appreciated for any suggestions to solve this error.

BadImageFormatException usually means architecture conflits.. Like trying to install a 32 bit assembly with a x64 install util for example.
Also in the pre-bind state information you can read this line:
WRN: A partial bind occurs when only part of the assembly display name
is provided.
WRN: This might result in the binder loading an incorrect assembly.
Which might indicate that you are not using a fully qualified name to load an assembly but just the type. Try specifying the fully qualified name of the assembly you are trying to load.

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

AppDomain.CreateInstanceAndUnwrap not working in a website

I have a very simple class CompiledFunction (MarshalByRefObject) - I try to create an instance of this in a new domain like so
var appDomainSetup = new AppDomainSetup();
appDomainSetup.ApplicationBase = Path.GetDirectoryName(typeof(CompilerService).Assembly.CodeBase);
var evidence = AppDomain.CurrentDomain.Evidence;
SandboxDomain = AppDomain.CreateDomain("Sandbox", evidence, appDomainSetup);
CompiledFunction<T> result = (CompiledFunction<T>)SandboxDomain.CreateInstanceAndUnwrap(
assemblyName: typeof(CompiledFunction<T>).Assembly.GetName().Name,
typeName: typeof(CompiledFunction<T>).FullName);
This works fine in a Console application, but in an ASP .NET MVC application I get the following exception - can anyone offer any suggestion as to why this is not working in a web app? The T parameter I am passing is System.Decimal

InnerException:

The problem was that the Assembly.Code base started with file:///{rest of path here} - when using Path.GetDirectoryName on such a path it replaces file:/// with a single forward slash; so you end up with "/c:\myfolder\myfile.dll"
Getting Uri to tell me the local path was the solution
if (SandboxDomain == null)
{
var appDomainSetup = new AppDomainSetup();
string appBase = typeof(CompilerService).Assembly.CodeBase;
//Added the following line
appBase = new Uri(appBase).LocalPath;
appDomainSetup.ApplicationBase = Path.GetDirectoryName(appBase);
var evidence = AppDomain.CurrentDomain.Evidence;
SandboxDomain = AppDomain.CreateDomain("Sandbox", evidence, appDomainSetup);
}

Looks like you did not properly copy Ems.Scripting assembly for web project or set wrong ApplicationBase for your new domain (more likely).
Path.GetDirectoryName call is suspicious in computing ApplicationBase property.
