I'm learning software developer and got this project of git hub to learn.
<https://github.com/the-best-flash/CSharpMiner>

The project's creator give us the follow instructions to execute this project in visual studio, but I don't understand the step number 2, (Change the dropdown that says "Debug" to say "Release")

**\*project's instructions**:

1. Load the solution file. \*.sln
2. Change the dropdown that says "Debug" to say "Release"
3. Select "Build -> Build Solution"
4. Navigate to the CSharpMinerProgram\bin\Release folder and copy the .exe, and .dll files to wherever you want to run the program from. (ex. C:\CSMiner)
5. Make a \bin folder wherever you put the .exe (ex. C:\CSMiner\bin)
6. Copy the .dll files from CSharpMinerProgram\bin\Release\bin to the \bin folder you just made.
7. Create a "config.conf" file in the same folder as the .exe (ex. C:\CSMiner\bin) you can follow the example further down.
8. Right click on the .exe and make a shortcut. Copy the shortcut to your desktop.\*

**I tried follow the project's instructions but appear this error:**
