Getting this error while building my project:- Compile Error:An assembly with the same identity 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' has already been imported. Try removing one of the duplicate references. - C:\projecthome\projectname\bin\Debug\Read_Input_Data_From_Excel.Runner.exe
How do I resolve this error ?
