I have the current file structure in my Visual Studio project:

• MyProject/
  • MyStartupProject/
    • bin/
      • Debug/
    • Program.cs
  • DependencyProject/
    • bin/
    • dlls/
      • MyAssembly.dll
    • Code.cs

My Main() function is inside MyProject/MyStartupProject/Program.cs. Inside Code.cs is a line var assembly = Assembly.Load("MyAssembly");, which is supposed to load MyProject/DependencyProject/dlls/MyAssembly.dll, but instead it causes the error

System.IO.FileNotFoundException: 'Could not load file or assembly 'MyAssembly' or one of its dependencies.
The system cannot find the file specified.'

However, everything runs perfectly fine if I copy MyAssembly.dll into MyProject/MyStartupProject/bin/Debug. How do I fix this reference so the project can find it under the dlls directory?

I resolved my issue by adding the following to my DependencyProject.csproj

<ContentWithTargetPath Include="dlls\MyAssembly.dll">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <TargetPath>MyAssembly.dll</TargetPath>
</ContentWithTargetPath>

This causes the dlls to be automatically copied into MyStartupProject/bin/Debug/.

Try to Change the status of MyAssembly.dll to Copy if new.

Update:

Add file

Update2:Is there a way I can get it to copy straight into Debug/ without moving the original out of the dlls/ directory?

Two solutions:

1. Change var assembly = Assembly.Load("MyAssembly"); to var assembly = Assembly.LoadFrom("dlls\MyAssembly.dll");.

2.
