I have c# application and when I made a change, I am getting the error message:
An unhandled exception of type 'System.TypeLoadException' occurred in WindowsFormsApplication1.exe
Additional information: Could not load type
'TradeIdeas.TIProData.OddsMakerColumnConfiguration' from assembly 'TIProData, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null’.
This message says the version number of dll (TIProData) is 1.0.0.0. I think there is a later version available. How can I tell the version number of a dll on my machine?

If you reference the dll in Visual Studio right click it (in ProjectName/References folder) and select "Properties" you have "Version" and "Runtime Version" there. In File Explorer when you right click the dll file and select properties there is a "File Version" and "Product Version" there.
With most Windows executables (DLL, EXE...), version and other details can be viewed using "Details" tab in "Properties" ( Alt + Enter ).
An assembly is a collection of types and resources that are built to work together and form a logical unit of functionality. Assemblies take the form of executable (.exe) or dynamic link library (. dll) files, and are the building blocks of . NET applications.
"Assembly File Version" is what shows when you right-click on a file and go to "properties" then the "details" tab.
How to manually determine if a file is an assembly. Start the Ildasm.exe (IL Disassembler). Load the file you want to test. If ILDASM reports that the file is not a portable executable (PE) file, then it is not an assembly.
You can get file version of file using PowerShell Get-Command cmdlet. In the above command, Get-Command get dll assembly file version of the specified file using FileVersionInfo. FileVersion property.
You can use Reflector, ILDASM or ILSpy to get the assembly version.
You usually can find ILDASM in C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\ildasm.exe (where v8.1A is the version of the Windows SDK installed).
