Building C# solutions from command line with Visual Studio 2010
Solution 1:
For solutions you can use:
devenv /build Release Solution.sln
or
devenv /build Debug Solution.sln
Solution 2:
if you open a visual studio command prompt from your start menu - then you can call MSBuild and give that either the .sln file or a specific .csproj file in order to build what you need
alternatively you can create a custom MSBuild file that takes care of the tasks.
one tip: make sure the version of MSBuild that you use is applicable to the target framework or tools version of the project
i.e. if you try and build a solution that was created in vs2010 with msbuild 3.5 then it will not recognise the 4.0 toolset of the project
