Toolkit for Independent .NET Developers


During the past three plus years I have been engaged in building several Windows .NET applications for the shareware/freeware market. This activity has been done as an independent developer.

Applications were built and distributed for the following areas: database, encryption, networking and file management

One of the key challenges in preparing for this project was insuring that I had a toolkit that enabled me to quickly and effectively build the various applications that were planned. To this end, I researched the web to find the best and most cost effective tools for use in a Windows .NET environment.

This article summarizes the tools I wound up using. My hope is that this will help jump start the work of independent .NET developers that are just starting and facing many of the issues I had to solve.

It supports all the major database platforms. ODBC and OLEDB support plus a generic Universal provider further extends the reach of this tool. AQB allows users to preview results for their query definitions in separate data grid.

Users of your application can define their queries using the visual interface and the SQL text is passed back to your application for processing.

The Core Edition does not contain a visual interface but allows you to build and parse SQL statements from within your application.

Overall, this was a singularly useful and powerful library/user interface for my database applications. While somewhat expensive, there appeared to be nothing else at a lower price range and only a few alternatives at much higher prices.

Points of Interest

The above mentioned tools were used to build a set of six database, encryption and file management applications. They were also used to build a set of networking libraries.

The code was built on top of the .NET 4.0 Framework (Full) using Visual Studio 2010 Ultimate Edition.

Primary selection criteria for the above tools included:

  1. Libraries did not charge royalties if they were included in your distributed application.

  2. Libraries had to encapsulate away the underlying complexity of the technology they wrapped (i.e. they had to be easy to use).

  3. The tools had to be cost effective, free if possible but relatively low priced if purchased.

    • Exceptions included
      RoboHelp for application help files.
      InstallShield Express for application setups.
      Active Query Builder for dynamic SQL building and parsing.
      Advanced Query Tool and querying multiple database platforms during testing.

  4. Where possible, the tools and libraries selected should not require the clients to already have specific products installed.

    • The Office Interop libraries were not used in the applications that I distributed because they required Word, Excel or Access to already be installed on the client.

    • The Office Interop libraries were, however, used in an Open Source version of the application code in order to remove dependencies on third party products that needed to be purchased in order to be included in source code development.

    • A similar exception was made for zip processing code. The C1Zip component from ComponentOne was used in the distributed applications while the DotNetZip library was used in the Open Sourced application code.

    • Database libraries for specific vendor platforms like SQL Server, Oracle, DB2, etc. required that the client machine have the database specific software pre-installed before the custom database libraries included in the data distributions could be used. Pre-installed software could be .NET Providers, OLEDB providers or ODBC drivers.

  5. Building code using the .NET libraries, when available for particular task, was preferred over third party libraries.

    • Examples of where .NET built-in libraries were used instead of third-party products include

      •  .NET encryption classes for AES, Triple-DES and DES encryption instead of third party product.
        .NET WinForms DataGridView control instead of the C1TrueDBGrid control.

    • Examples of where .NET did not provide built-in capabilities include

      • PGP Encryption
        SFTP File Transfers
        Office document creation and editing
        Robust ZIP functionality
