Cauldron.Interception.Fody Problem

[LaborJos]

I am using Cauldron.Interception.Fody. Problems occur after updating nuget to 2.1.0. The Fody Version I use is v3.0.3.

Fody: The weaver assembly 'Cauldron.Interception.Fody, Version = 2.0.0.39, Culture = neutral, PublicKeyToken = null' references an out of date version of Mono.Cecil.dll. Expected strong name token of '1C-A0-91-87-7D-12-CA-03' but got '50 -CE-BF-1C-CE-B9-D0-5E '. The weaver needs to update to at least version 3.0 of FodyHelpers.

This is probably a problem with the FodyCecil version of this commit (https://github.com/Capgemini/Cauldron/commit/56307f15491e1af51d35e189e8bc60a9ff20e031). There is currently no FodyCecil 2.5.0 on nuget.org.

Hi,

There are some changes in Fody >= 3.0.0 ... Version 2.0 of Cauldron is not compatible with it. Please use the Cauldron.Interception.Fody 3.0.2-beta instead.

I will try my best to have a stable release this month. For the mean time, please use the beta.

There is actually a bug in the property interceptor, where it might run into an exception if the property does not have a setter and a getter depending on the interceptor. The Name property in DocumentViewModel1 might be missing a setter in this case.

[LaborJos]

"Name" has a setter. As you said, there is a property in class that does not have a setter.

So this issue is also resolved in the next release version? If not, please let us know the alternative.

[reflection-emit]

The issue will be resolved in version 3.0.4 ... for now you could make Cauldron ignore the property.
