Got up and running in seconds - you've certainly led we customers into the \"Pit of Success.\" :)\n \nThis may be already known, but I encountered runtime TypeInitializationException(s) when using types (such as ZipFile and ZipEntry) in ZipSL 1.9.1.8 from with a Silverlight application. After building and running from source, it was clear that the problem\n was related to the static type construction at lines such as:\n \nAlternateEncoding = System.Text.Encoding.GetEncoding(\"IBM437\");\n \n \nAppears this encoding is not one of the \nfour supported encodings in SL4. I was able to avoid the issue by altering the behavior where necessary with preprocessor directives, for example:\n \n \n \n \n#if SILVERLIGHT\n\tAlternateEncoding = System.Text.Encoding.GetEncoding(\"utf-8\");\n#else\n\tAlternateEncoding = System.Text.Encoding.GetEncoding(\"IBM437\");\n#endif\n \nI was able to do this to the point where my use cases were covered; would be happy to submit a patch if I had some guidance on the most appropriate strategy for dealing with this.\n \nYours,\nDavid", "LastUpdatedDate": "2014-06-18T08:41:39.4-07:00", "PlannedForRelease": "", "ReleaseVisibleToPublic": false, "Priority": { "Name": "Low", "Severity": 50, "Id": 1 }, "ProjectName": "DotNetZip", "ReportedDate": "2011-08-09T03:56:57.833-07:00", "Status": { "Name": "Proposed", "Id": 1 }, "ReasonClosed": { "Name": "Unassigned" }, "Summary": "ZipSL runtime error - TypeInitializationException due to IBM437 Encoding defaults", "Type": { "Name": "Issue", "Id": 3 }, "VoteCount": 20, "Id": 14049 }, "FileAttachments": [ { "FileId": 4244, "FileName": "DotNetZip.1.9.1.8.zip", "DownloadUrl": ".\\4244" } ], "Comments": [ { "Message": "Code does not work without this patch.
