I’ve been updating our company’s Christmas bake-off site and as part of the update I added the Microsoft.Identity.Web project to help with authentication and accessing the Graph API. This project doesn’t currently have a NuGet package though one is apparently in the works so I included it by taking a Read more…
I’ve previously posted about how to cope with nullable values retrieved from a SqlDataReader but it’s also necessary to account for nulls when passing values through to a SQL operation such as a stored procedure. sp__set_completed.sql If you want you’re stored procedure to accept nulls then you first need to Read more…
I maintain a library called PGPCore for using PGP encryption in C#, in order to test how this performs when processing large files I needed to create a large file full of random data to check it was encrypting/decrypting as expected. After a bit of searching the answers to this Read more…

Previously when I’ve wanted to read a blob from Azure Storage I’ve opened it as a CloudBlockBlob which allows you to read it using just OpenReadAsync(). If you want to use an ICloudBlob then you need to provide AccessCondition, BlobRequestOptions and OperationContext parameters, these can also be used with the Read more…
If you’re using Entity Framework with a legacy database then you may well have single character status flags in some of the columns such as “O” = Operational, “M” = Marketing. Ideally these would be numeric IDs that match to a separate status table which would allow the IDs to Read more…
