Launch Microsoft's Visual Studio.
Create a new project or open an existing.
Add a reference to SautinSoft.Document:
You may do this by two ways:
Using Nuget (fast way):
(Solution Explorer->right click by "References"->Manage Nuget Packages...->In the tab "Browse" type "SautinSoft" and find the "SautinSoft.Document")
Second (old good way): Adding a reference to the "SautinSoft.Document.dll" file:
First of all, download the Document .Net package. Unzip it at any place in your computer and find the assembly file "SautinSoft.Document.dll".
(Solution Explorer->right click by "References"->Add Reference...->Browse "SautinSoft.Document.dll")
Well done! Now you have API to create, modify, parse, convert, replace, merge documents in PDF, DOCX, RTF, HTML and Text formats!
Here you will find the Collection with Code Examples in C# and VB.Net.
