RDLC RunTime Bug - "Native compiler return value: ‘[BC40000] 'RequestMinimum' is obsolete" - Microsoft.ReportingServices.RdlObjectModel.ExpressionParser.VBFunctions

[pri-kise]

1. Describe the bug
When I copy tablix with some expressions in RDLC, then they get the full assembly path added in front of the function name

2. To Reproduce
Steps to reproduce the behavior:

1. Copy the Vat Clause Tablix of the Sales Invoice Header
   The expression

<FilterExpression>=Cstr(Len(Fields!Code_VATClauseLine.Value))</FilterExpression>

is converted to

<FilterExpression>=Microsoft.ReportingServices.RdlObjectModel.ExpressionParser.VBFunctions.Cstr(Len(Fields!Code_VATClauseLine.Value))</FilterExpression>

3. Expected behavior
It shouldn't be a problem if the full path is used or at least we should get some better error.

4. Actual behavior
Currently the following error is displayed

Rendering output for the report failed and the following error occurred: An unexpected error occurred while compiling expressions. Native compiler return value: ‘[BC40000] 'RequestMinimum' is obsolete: 'Assembly level declarative security is obsolete and is no longer enforced by the CLR by default. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information.'.’.

I close this issues since it probably won't be fixed here, but I want to provide a public solution for anybody having the same problem.

I had had the same error message (in my docker container) but another reason.
One line in the report code (inside the rdlc file) was not correct "in line".

In the BC Environment there was this error:
