Re: [Firebird-net-provider] FW: What is this error: Field not found:System.Data.Common.DbProviderManifest.ConceptualSchemaDefinitionVersion3

[M. A. C. <mc...@mc...>]

<div><div>It is likely that this is happening because I installed Net 4.5 and Firebird provider stopped working. Thus, I uninstalled 4.5 and reinstalled Net 4.0 and Visual Studio 2010.</div><div><br></div><div>When executing a Stored Procedure is the error message: "Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version = 4.0.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089'." This error is related to the existence of the Net 4.5, right?</div><div><br></div><div>Where should I change my source code so that it is in the form of .Net 4.0? It took me 3 days to reinstall the system again and wonder, if necessary, the&nbsp;Firebird's&nbsp;provider works with .Net 4.5?</div></div><div><br></div><div>Thanks,</div><div>Marco Castro</div><br><b>----- Original Message -----</b><br>
