Hi,
According to
some forum posts:
".csproj" is a Visual Studio .NET C# Project file extension. This file will have information about the files included in that project, assemblies used in that project, project GUID and project version etc. This file is related to your project. It will be automatically generated when we create
".sln" is a structure for organizing projects in Visual Studio. It contains the state information for projects in .sln (text-based, shared) and .suo (binary, user-specific solution options) files. We can add multiple projects inside one solution.
.sln: Solution File to open the solution in VS Studio
vs2010.sln: Solution File to open the solution in VS Studio 2010
rxsln: Ranorex Solution File to open the solution in Ranorex Studio (similar to VS Solution file)
