I am running my application in VS2012 and I am getting a runtime error;
When I look in the "Original Location" I see mscorlib.dll, but not mscorlib.pdb.
Why is this happening and how do I fix it?
Method 1: Download Mscorlib. First of all, you need to download Mscorlib. dll to PC from our site. Copy the file to the program install directory after where it is missing the DLL file. Or move the DLL file to the directory of your System (C:\Windows\System32, and for a 64 bit in C:\Windows\SysWOW64\).
Search for all the Mscorlib. dll files in the %systemroot%\Microsoft.NET\Framework folder and the %systemroot%\Microsoft.NET\Framework64 folder if the folder exists. Click on each of the files, view properties, and click version tab to determine the version installed.
Answers. It stands for Microsoft's Common Object Runtime Library and it is the primary assembly for the Framework Common Library.
Goto Tools, Options, Debugging, General, Enable Just My Code
This will prevent the debugger from trying to launch on a Internal .NET Framework Assembly.
