EnterpriseLibrary.TransientFaultHandling by: Microsoft

The Transient Fault Handling Application Block for Windows Azure ("Topaz") provides a set of reusable and testable components for adding retry logic into your Windows Azure applications leveraging Windows Azure SQL Database, Windows Azure storage, Service Bus and Caching Service. This makes your Windows Azure application more reliable and resilient to transient faults (such as temporary network connectivity issues or temporary service unavailability). This improves overall application stability.

FastMember by: Marc Gravell

In .NET reflection is slow... well, kinda slow. If you need access to the members of an arbitrary type, with the type and member-names known only at runtime - then it is frankly hard (especially for DLR types). This library makes such access easy and fast.

FastReport.OpenSource by: Fast Reports Inc.

FastReport Open Source provides a free report generator for .NET/.NET Framework. You can use the FastReport Open Source in MVC, Web API, console applications. FastReport is written in C# and it is compatible with .NET Framework 4.6.2, .NET 6 and higher. Extendable FastReport architecture allows creating your own objects, export filters, wizards, and DB engines. - FastReport is a band-oriented report generator. There are 13 types of bands available: Report Title, Report Summary, Page Header, Page Footer, Column Header, Column Footer, Data Header, Data, Data Footer, Group Header, Group Footer, Child, and Overlay. In addition, sub-reports are fully supported. - A wide range of band types allows creating any kind of report: list, master-detail, group, multi-column, master-detail-detail and many more. - Wide range of available report objects: text, picture, line, shape, barcode, matrix, table, checkbox. - Reports can consist of several design pages, which allows reports to contain a cover, the data and a back cover, all in one file. - The Table object allows building a tabular report with variable number of rows and/or columns, just like in MS Excel. Aggregate functions are also available. - Powerful, fully configurable Matrix object that can be used to print pivot tables. - Report inheritance. For creating many reports with common elements such as titles, logos or footers you can place all the common elements in a base report and inherit all other reports from this base. Data Sources: - You can get data from XML, CSV, JSON, MS SQL, MySQL, Oracle, Postgres, MongoDB, Couchbase, Raven DB, SQLite. - FastReport has the ability to get data from business objects of IEnumerable type. - Report can contain data sources (tables, queries, DB connections). - Thus, you can not only use application-defined datasets but also connect to any database and use tables and queries directly within the report. FastReport Open Source can save documents in HTML, BMP, PNG, JPEG, GIF, TIFF, EMF. PDF export is available as a plugin.
