A managed wrapper around Microsoft's delta compression application programming interfaces.
DeltaCompressionDotNet is licensed under the Microsoft Public License (MS-PL).
It's worth noting that large parts of DeltaCompressionDotNet's implementation are generic (we're talking rangeCheck, here) and while this wrapper represents my own, original work, it would be difficult to enforce the license against anything but a slavish copy.
To this extent, the library is also licensed under the DBAD-PL.
Install the DeltaCompressionDotNet package from NuGet.
var compression = new MsDeltaCompression(); /* or PatchApiCompression(); */
compression.CreateDelta(sourcePath, destinationPath, deltaPath);
CreateDelta returns void; if the function is not successful in creating a delta a Win32Exception is thrown. The NativeErrorCode of the exception should contain the value of GetLastError(), which may describe the failure.
var compression = new MsDeltaCompression(); /* or PatchApiCompression(); */
compression.ApplyDelta(deltaPath, sourcePath, destinationPath);
ApplyDelta returns void; if the function is not successful in applying a delta a Win32Exception is thrown. The NativeErrorCode of the exception should contain the value of GetLastError(), which may describe the failure.
Both MsDeltaCompression and PatchApiCompression implement IDeltaCompression.
PatchAPI (concomitant class: PatchApiCompression) is available from Windows 2000; MSDelta (concomitant class: MsDeltaCompression) is available from Windows Vista.
DeltaCompressionDotNet targets the .NET Framework 4.5, which is only available on Windows Vista and later.
Nothing prevents you from reducing the library target to a version of the .NET Framework that runs on operating systems earlier than Windows Vista, but if you're lucky enough to be using the .NET Framework 4.5 then you should prefer MsDeltaCompression over PatchApiCompression where possible.
The library is not tied to any particular architecture, the code should execute on x86, x64 and ia64.
It's unlikely that DeltaCompressionDotNet will work on operating systems other than Windows (à la Mono).
If you encounter a scenario where the wrapping around PatchAPI or MSDelta doesn't work as you expect, you're welcome to report a bug, initiate a pull request or send an email to t AT speot DOT is. The latter method is likely to elicit a response, but not guaranteed.
The above applies equally for feedback.
