Hi<BR>I have installed an assembly into the GAC, but I&#039;m triying to use it in another project and I always get an error message saying that some reference is missing.<BR><BR>I added the next line into the "machine.config" file:<BR>&#060;add assembly="nsBaseDatos, Version=1.0.1137.17329, Culture=neutral, PublicKeyToken=e6cfa20a4310c0e9"/&#062; (I copied the properties from the assembly directory, under winnt)<BR><BR>Could anybody please tell me what am I missing?. Everywhere I find how to install the assembly, but I haven&#039;t found how to use it then.<BR><BR>Thanks in advance!
